Monitor Products’ MS49 and SMS49 crystals greatly reduce the space required by conven-
tional MM49 mounted crystals. Their low height allows them to be vertically mounted
between circuit boards and affords superior protection against shock and vibration. Our
resistance-welded packages offer excellent aging characteristics and may be used with all
types of wave soldering and vapor cleaning equipment.

CRYSTAL CORRELATION THEORY
Series Resonance:
Anti-Resonance Parallel:
At series resonance, the crystal looks
resistive in the circuit, and correlation of
frequency is not a problem. It must be
specified if unit is to be manufactured at
series or at a particular load capacitance.
Crystals operating at anti-resonance will look inductive
in the circuit. Changes of reactive values in the circuit
will change the crystal frequency. If the crystal is to be
used at anti-resonance, the load capacitance should
always be specified. The load capacitance C is the
L
dynamic capacitance of the total circuit as measured across the crystal terminals.
