12 MHz Crystal + 20pF capacitors
100 units available with a short lead time.
A 12.000MHz quartz crystal in a standard HC49/US short-style package with two 20pF load capacitors included. The crystal has 30PPM tolerance and 50PPM stability, making it precise enough for USB timing, long-term timekeeping, and RF/PLL/VCO applications. The breadboard-friendly package works with any microcontroller that requires an external crystal.
To use, connect the two pins to XTAL-in and XTAL-out on your microcontroller (the package is symmetric, so either pin works) and place one 20pF capacitor from each crystal pin to ground. Check your microcontroller datasheet for any additional components such as a 1MΩ feedback resistor.
