TYPE CRK, CRA
(CERASONATOR
CRK
Description
• Ceramic resonators using external capacitors/built-in
capacitors for the kHz band designed and produced with
application of Toko's experience relative to piezo materials,
precision manufacturing and soldering technology.
• Applicable oscillation frequency range
CRK: 380 to 680kHz
CRA: 455 to 500kHz
Features
• Precise oscillating frequency without adjustment.
• CRK type is soldered ceramic element, and High reliability.
• May be used with a variety of ICs.
• Load capacitors (C1, C2) not required for CRA type.
• RoHS compliant
Applications
• Reference signal oscillations for — Microcomputers
(household electronics, OA equipment)
• Remote controlling — TV's, VTRs, air-conditioners, CD
players, lighting apparatus.
• Digital applications equipment including measuring
instruments, communications equipment, toys, etc.
