FA-12832.0000MF20X-K3 is a MHz-range crystal unit designed for both RF reference and clock applications. It operates across a nominal frequency range of 19.2 MHz to 54 MHz with fundamental mode operation, featuring frequency tolerance of ±10 × 10?6 for RF reference and ±30 × 10?6 for clock applications at +25°C. The unit supports load capacitance from 6 pF to infinity and exhibits motional resistance (ESR) ranging from 150 O maximum at 19.2–20 MHz down to 60 O maximum at 26–54 MHz. Operating temperature range extends from -40°C to +85°C (with optional +105°C capability), storage temperature from -40°C to +125°C, and frequency aging of ±1 × 10?6/year maximum in the first year at +25°C. This crystal unit is ideal for precision timing in RF systems, telecommunications, automotive electronics, and consumer devices requiring stable frequency references.
