CX2HSM CRYSTAL
Miniature SMD Crystal for Series Oscillators
16kHz to 600kHz
FEATURES
Frequency Range 16kHz to 600kHz
High shock resistance
Low ageing
Designed for low power applications

DESCRIPTION
CX2HSM crystals consist of a high quality tuning fork resonator in a
rugged, hermetically sealed ceramic package. CX2HSM crystals are
intended for use in Series (two cascaded inverters) oscillator circuits.
