MC Series kHz Range Crystal Units

Epson MC Series kHz Range Crystal Units are SMD devices that use the piezoelectric effect to produce a constant frequency. Tuning-fork crystal units have a U-shaped chip that oscillates from side to side to enable them to cover frequencies in the kilohertz band, such as 32.768 kHz, which is commonly used as a clock frequency. Epson boasts an extensive lineup of kHz-band tuning fork crystal units for a wide range of applications such as a microcomputer and small communication devices.
