LOW PROFILE CRYSTALS

MS49 SMS49

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

dynamic capacitance of the total circuit as measured across the crystal terminals.
