## Description

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. Key Features 12.000MHz Frequency – Precision quartz crystal 30PPM Tolerance, 50PPM Stability – Suitable for USB and high-precision timing HC49/US Short Package – Standard, breadboard-friendly form factor Includes 20pF Capacitors – Two load capacitors included Ideal For USB-capable microcontroller circuits Real-time clock and timekeeping applications RF, PLL, and VCO driving circuits Breadboard prototyping with AVR, PIC, and ARM microcontrollers Package Contents 1× 12MHz quartz crystal (HC49/US) 2× 20pF ceramic capacitors

**Product Type:** physical
