12 MHz Ceramic Resonator / Oscillator
Discontinued
A 12MHz ceramic resonator with built-in load capacitors and breadboard-friendly 0.1" pin spacing. Ceramic resonators are a convenient alternative to crystals — they include the required stability capacitors inside the package, so fewer external components are needed. With 0.5% accuracy, they are well suited for general microcontroller clocking and UART baud-rate generation.
To connect, wire the two outer pins to XTAL-in and XTAL-out on your microcontroller (the package is symmetric, so either outer pin works) and connect the centre pin to ground.
Key Features
- 12MHz Frequency – Common clock speed for microcontrollers
- Built-In Load Capacitors – No external capacitors required
- 0.5% Accuracy – Sufficient for UART, SPI, and general timing
- Breadboard-Friendly – 0.1" (2.54mm) pin spacing
- 3-Pin Package – Simple symmetric wiring
Ideal For
- Microcontroller clock source (AVR, PIC, ARM)
- UART and serial baud-rate generation
- Breadboard prototyping
- General-purpose timing circuits
Package Contents
- 1× 12MHz ceramic resonator
Note: For applications requiring ultra-high precision (USB timing, long-term timekeeping, RF/PLL/VCO), use a crystal oscillator or temperature-compensated oscillator (TCXO) instead.
