VC-TXO-35SM

VC-TXO-35SM SERIES VC-TCXO The VC-TXO-35SM is a VC (Voltage Controlled) TCXO (Temperature Compensated Crystal Oscillator) featuring very tight stability over a wide temperature range. The small subminiature SMD ceramic package measures 3.2 x 5.0 x 1.5 mm. The voltage control has a tuning range of ± 5 ppm minimum. The low profile package is ideal for wireless communications applications. FEATURES • Highly stable output • Wide temperature • Voltage control function • Small footprint • Tape and Reel (1,000 pcs.)
