NOTE: P1, P2 and P3 are same for all chip inductor series. Keeping the same dimensions for guide hole and pocket pitch (P1), pocket pitch (P2), guide
hole pitch (P3) and tape width (8mm) for all series, enables the packaging machine to maintain the same settings while changing models. The only differ-
ence between the series are the parts per reel which contribute to a different length of tapes/reel per model.

Competing Chip Inductor Types
Capacitor and resistors are available in a wide variety of sizes and component values and it is possible to purchase
almost any value, tolerance or other rating. Inductors, on the other hand, are not so readily available and engineers
may find it necessary to wind their own inductors to get a specific value of inductance.
There are mainly 3 varieties of inductor in common use today and they are wire-wound, multi-layer and drum core
chip inductors. The primary differences between these competing types are the core material used to enhance the
inductance of coil and the construction method. Wire is wound around a ceramic or ferrite bobbin or in the case of
multi-layer the coil is formed by interconnecting layers of conductive material printed on a ceramic substrate.
Table 2.0 indicates that the performance merits of wire-wound inductors versus the alternative multi-layer and drum
core platforms. If price were the only consideration then, of course, there would be no market available for wire-wound
chip inductors. But price is not the only consideration, since RF engineers must also consider the needs of the
application in terms of Q factor, Idc (maximum current carrying capacity). Rdc (resistance at dc), Tolerance and
SRF (self-resonant or series resonant frequency).

RF CHIP INDUCTORS
Application Notes
The Inductor Basics
An inductor is formed by winding a wire around a ceramic or ferrite core to increase the magnetic flux linkage between
the turns of the coil. The majority of high frequency inductors above 50MHz are formed on a ceramic bobbin or sub-
strate. Nonmagnetic cores (ceramic cores) have the opposite effect to a magnetic core in that they reduce instead of
increase the inductance of the coil. Ceramic cores are mainly used to reduce the RF core losses as the high frequency
currents mainly flow near the surface of the conductor. The resistance that a conductor offers to the high frequency
alternating current is much greater than the resistance of the same conductor to direct current (dc) and is known as the
skin effect. The skin effect is a characteristic of conductors that carry alternating current and is much more pronounced
in coils than in straight conductors.
Skin effect causes the current in the conductor to be much denser near the surface of the conductor than at its centre.
Consequentially, as the instantaneous value of the alternating current changes the inductance of a conductor in its
interior is much greater than the instantaneous inductance near its surface. The result is more current flows near the
surface or "skin" of the conductor than at its centre. Since the inductance of the coil increases proportionally to the
increasing frequency, the skin effect also increases as the frequency is increased.
Another source of loss is the dielectric material used to form the body of the inductor. There is no perfect insulator and
so dielectric losses can not be avoided at very high frequencies. Dielectric losses, like skin effect also tend to increase
the effective resistance of a coil at high frequencies.
Whilst there is no perfect component compared to a resistor or capacitor, inductors are probably the component most
prone to changing its performance over frequency. Figure 1.0 illustrates what a real world inductor looks like at RF fre-
quencies and the resultant equivalent circuit.

that exists in a wire. Fig. 1.0 B shows a representation of the lumped resistive, capacitive and inductive component

RF CHIP INDUCTORS
Application Notes
The Inductor Basics (continued)
The effect of Cd can have a dramatic effect upon the impedance of the inductor as illustrated in Fig 2.0, because
"fringe" effects become dominant at high frequencies. At low frequencies the inductor's reactance parallels that of an
ideal inductor. With increasing frequency the reactance of the inductor departs from the ideal curve and increases at a
much faster rate until it reaches a peak value at the inductor's parallel resonant frequency (Fr). Above Fr the inductor's
reactance begins to decrease with increasing frequency and thus the inductor begins to look like a capacitor. The
series resistance (Rs) of the coil prevents the impedance of the inductor from reaching infinity at resonance (Fr).
Another effect of Rs is to broaden the resonant peak of the impedance curve at Fr.
Comparisons made between inductors at near to Fr will produce an inaccurate representation of the inductor's perfor-
mance. This can lead to problems in the end application since the performance of one inductor to another may vary
quite markedly since the performance of the inductor is dominated by the parasitic content (distributed capacitance Cd)
of the inductor.

Application Notes
Q factor / SRF
The ratio of an inductor's reactance (XL) to its series resistance (Rs) is often used as measure of the quality factor of
the inductor. The larger the ratio, the better the inductor. The quality factor of an inductor is often referred to as the Q
of the inductor. If the inductor were constructed from a perfect conductor (zero loss), its Q would be infinite. Of course
this is impossible, and so the Q of an inductor will always have some finite value.
The Q factor, Fr and SRF of an inductor are directly linked to one another. If the test frequency is near Fr or SRF, the
inductor results may be misleading by very wide margins, since the result is dominated by distributed capacitance
reactance. To overcome this problem, the test frequency of the inductor is normally located at a point on the inductor's
curve where the reactance of the inductor approaches that of an ideal inductor, so that component to component
variations are kept to a minimum since the parasitic contribution is also at a minimum. To overcome this problem, RF
engineers should select an inductor with the highest test frequency possible to guarantee the quality of the inductor.
At low frequencies, the Q of an inductor is very good because the only resistance in the winding is the dc resistance of
the wire which is very small (Fig. 2.0). As mentioned earlier, as the frequency increases, the skin effect increases to
degrade the Q of the inductor. At low frequencies, the Q increases directly inline with the reactance (XL) since the skin
effect has not become noticeable. The Q continues to rise, but as the frequency approaches Fr, the skin effect starts to
become a dominant, reducing the rate of increase. At Fr, the series resistance and reactance are increasing at the
same rate. Above Fr, the distributed capacitance Cd and skin effect of the winding combine together to decrease the
Q of the inductor to zero at SRF.
Understanding Inductor Curves
RF design engineers require inductors to meet the following requirements:
1. Low cost
2. Compatibility to the competition
• Q, SRF and useable frequency range => competition
3. Component to component variation small
4. Performance approachs that of an ideal inductor
• High Q (low series resistance)
• High SRF (low distributed capacitance)

3.0 Characteristics of a Real World Inductor Vs Ideal Inductor
Determining the Inductor Equivalent Circuit
To determine the inductor equivalent circuit, an RF engineer must deduce the value of Rs and Cd from the curves sup-
plied by the inductor manufacturer. To do this, the following equations can be used. Of course, the values deduced
only apply at one specific frequency. The recommended frequency at which the inductor is used within the application
should be an order of magnitude (÷ 10) below the SRF, and preferably not near than ½ Fr.
