TYPE CRK (kHz Band)
Description
• C external kHz band ceramic oscillating elements
using TOKO’s experience in piezo material, precision
manufacturing and soldering technology.
• Applicable oscillating frequency range: 380 — 680kHz
.
Unit: mm
Features
• Precise oscillating frequency without adjustment
• Soldered connections as opposed to spring tension
technique for higher reliability.
• May be used with a variety of ICs.
Applications
• Reference signal oscillators for microprocessors
(household electronics, OA equipment).
• Reference signal oscillators for remote controls
(TVs, VCRs, air-conditioners, CD players, lighting).
• Digital applications equipment including measuring
instruments, communications equipment, toys, etc.
