A 16.000 MHz quartz crystal in the HC49/US short-style package, supplied with two 20pF load capacitors. The crystal provides higher precision than ceramic resonators, with 30 PPM tolerance and 50 PPM stability — suitable for USB timing, long-term timekeeping, and RF/PLL/VCO applications.

The breadboard-friendly package has two pins with symmetric pinout. Connect one pin to XTAL-in and the other to XTAL-out on your microcontroller, with one 20pF capacitor from each crystal pin to ground. Check your microcontroller datasheet for any additional components (e.g. a 1 MΩ feedback resistor).
