Handling Notes
1. Shock & Drop • Vibration
2. Cleaning
Do not inflict excessive shock and mechanical vibration that
exceeds the norm, such as hitting or mistakenly dropping, when
transporting and mounting on a board. There are cases when
pieces of crystal break, and pieces that are used become
damaged, and become inoperable. When a shock or vibration that
exceeds the norm has been inflicted, make sure to check the
characteristics.
Since a crystal piece can be broken by resonance when a crystal
device is cleaned by ultrasonic cleaning. Be careful when carrying
out ultrasonic cleaning.

4. Mounting Precautions
Leaded Devices
The special glass, located where the lead of the retainer base comes out, is aligned with the coefficient of thermal expansion of the lead, If
the glass is damaged and cracks appear, there may be cases in which performance deteriorates and it fails to operate.
Consequently, when making the device adhere closely and applying solder, align the gap of the hole of the board with the gap of the lead
and insert without excessive force.
When making the device adhere closely to a through hole board and applying solder, be careful that the solder does not get into the metal
part of the retainer base and cause a short. Putting in an insulation spacer is one more method of preventing a short circuit.
When the lead is mounted floating, fix it as far as possible so that contact with other parts and the breakage due to the fatigue, and the
mechanical resonance of the lead will not occur.
When the lead is bent and used, do not bend the lead directly from the base, separate it 0.5mm or more and then bend it. When bending,
before attaching to the board, fix the place where the lead comes out in advance and attach it after bending so that a crack does not occur in
the glass part.
Surface Mount Devices
The lead of the device and the pattern of the board is soldered on the surface. Since extreme deformation of the board tears off the pattern,
tears off the lead metal, cracks the solder and damages the sealed part of the device and there are cases in which performance deteriorates
and operation fails, use it within the stipulated bending conditions. Due to the small cracks in the board resulting from mounting, please pay
sufficient attention when attaching a device at the position where the warping of the board is great.
When using an automatic loading machine, as far as possible, select a type that has a small impact and use it while confirming that there is
no damage.
Surface mount devices are NOT flow soldering compatible.
5. Storage Condition
Since the long hour high temperature and low temperature storage, as well as the storage at high humidity are causes of deterioration in
frequency accuracy and solderability.
Parts should be stored in temperature range of -5 to +40°C, humidity 40 to 60% RH, and avoid direct sunlight. Then use within 6 months.

Handling Notes
The oscillation start-up conditions are described as
RL R
and in order to oscillate the crystal unit accurately, it must be designed such that the negative resistance of the oscillation
circuit becomes bigger comparing with the resonance resistance value at the time of loading. This ratio is called oscillation
margin degree MOSC and it is one of critical factors when designing the oscillation circuit and is described as below.
For oscillation circuit designing conditions, it is recommended that an oscillation circuit be designed using a negative
resistance of a value five to ten times or more larger than RL calculated from the resonance resistance specification value.
M
OSC R / RL 5
In a steady oscillation state, the load resonance resistance is given as follows:
RL R
The mutual conductance of the oscillation circuit decreases after the oscillation has started to continuously compensate for
the power loss due to the load resonance resistance of the crystal unit, which continues oscillation.
The frequency condition is given as follows:
XL XC, XL XC 0
As shown in the following figure, the reactance of the crystal unit varies to a value matching the load capacitance of the
oscillation circuit CL XC. Thus an oscillation frequency is determined.

unit changes with load capacitance CL of the oscillation circuit.

(5) Method of checking oscillation circuit
①Some ICs have a low upper-limit value of usable frequency, so refer to individual IC catalog to make sure that the IC can
oscillate a crystal unit with an adequate negative resistance.
②The following figure shows an example of a CMOS oscillation circuit. Check resistance Rsup is connected in series with
the crystal unit to check the negative resistance. Use 3 to 22pF for C1 and C2, and see the table below for values of check
resistance.

③Using a spectrum analyzer or oscilloscope, check that every oscillation is normally activated while turning the power on
and off several times. For oscillation circuits with no power regulator ICs, carefully check changes in the negative
resistance against supply voltage and in frequencies.
④When oscillation is normal, remove the check resistance before using the crystal circuit.
⑤If oscillation is unstable or is not generated, gradually decrease the values of C1 and C2 until normal oscillation is obtained.
⑥If normal oscillation cannot be generated near 10MHz or near 20MHz, replace the IC with a new one suitable for higher
frequencies.
(6) Load capacitance and oscillation frequency of transistor/fundamental crystal oscillation circuit
Viewed from the connection terminals of a crystal unit, the load capacitance CL of an oscillation circuit is generally comprised
of C1, Ct, C2, and C3 if stray capacitance of the circuit and the capacitance between base and emitter of the transistor are
ignored. Since trimmer capacitor is adjusted to CT = MIN. to MAX. for zero adjustment of the oscillation frequency, the value
of CL at this time can be obtained from the following equation.

Select each circuit constant so that the adjustment ranges of upper and lower frequencies of this circuit are even on the
basis of the frequency of a single crystal unit measured using a specified load capacity, and that the margin of ±8 to 10 10-6
of the room temperature deviation of the crystal unit can be reserved.
To prevent the decrease in the negative resistance, always connect the crystal unit to the base of the transistor. For
transistors used for oscillation circuits, hfe and fT are important.
To obtain the large negative resistance with small current consumption, select a transistor for high frequency amplification
with hfe of over 250 and fT of 1GHz or more.
(7) Transistor third overtone oscillation circuit
①The resonance circuit comprised of L2 and C3 is required on the emitter side for preventing fundamental mode crystal
oscillation. Set the resonance frequency to a value higher than the intermediate between fundamental wave frequency and
third overtone frequency.
②Use L1, referred to as an elongation coil, to connect the load capacitance of the oscillation circuit in series. R1 prevents
self-excited oscillation by L1. Since it is difficult in general to design the oscillation circuit having adequate negative
resistance in the overtone oscillation frequency band, there are no other effective means of obtaining adequate oscillation
margin except for preventing the increase of load resonance resistance RL of the crystal unit.

To prevent decrease in the negative resistance, connect the crystal unit to the base of the transistor as in the fundamental
mode crystal oscillation circuit. To use the crystal circuit for both oscillation and multiplication, connect a parallel resonance
circuit having multiplication frequency as resonance frequency to the collector of the transistor.
When selecting circuit constants for zero adjustment range by trimmer capacitor, set the constants to values obtained by
adding approx. 12 to 1510-6 to the room temperature deviation of the crystal unit, centering the value obtained by
measuring the crystal unit with load capacitances in series. (When the room temperature deviation specification of the crystal
unit is 1010-6)
(8) Excitation power of oscillation circuit
Normal operation of crystal units is not assured when excitation power is raised. The allowable excitation power varies
depending on the shape of the crystal unit or the stability of targeted frequency. When highly accurate oscillation is required,
however, it is recommended to use an oscillation circuit with an excitation power of 5 to 50 µW or less. For other cases, refer
to individual relevant crystal units on the pages of the catalog.
(9) Precautions for designing printed circuit board
Be sure to design printed circuit board patterns that connect a crystal unit with other oscillation elements so that the lengths
of such patterns become shortest possible to prevent deterioration of characteristics due to stray capacitances and wiring
inductance. For multi-layer circuit boards, it is important not to wire the ground and other signal patterns right beneath the
oscillation circuit.
