5.000M~120.000MOven Controlled Crystal Oscillator(OCXO) POC3627
The POC2522-MHz series by Zhejiang A-Crystal is a high-performance SMD OCXO (Oven-Controlled Crystal Oscillator) with a frequency range of 10.0MHz to 100.0MHz, featuring ±0.1ppm initial accuracy and ultra-low phase noise (-170dBc/Hz). Compact in size (25.4×22.1×13.2mm), it operates across a wide temperature range (-45℃ to +90℃), making it ideal for microwave communications, radar systems, and precision instruments. Key features include voltage-controlled frequency tuning (±0.4ppm), fast warm-up (5-minute stabilization), and low power consumption (2.0W steady-state). Compliant with RoHS standards.
