## Description

A 16 MHz ceramic resonator with built-in load capacitors, providing a simple clock source for microcontrollers. The 3-pin package has 0.1" (2.54 mm) pin spacing for direct breadboard use — connect the two outer pins to XTAL-in and XTAL-out (the package is symmetric, so either outer pin works for either connection) and the centre pin to ground. With 0.5% frequency accuracy, ceramic resonators are suitable for general-purpose microcontroller clocking and UART baud rate generation. This 16 MHz resonator is a direct match for the Arduino Uno clock frequency, making it ideal for building Arduino-compatible circuits on a breadboard. Tip: For applications requiring higher precision (USB timing, long-term timekeeping, RF/PLL/VCO), use a crystal oscillator or temperature-compensated oscillator instead. Specifications Frequency – 16 MHz Accuracy – ±0.5% Type – Ceramic resonator with built-in capacitors Pins – 3 (XTAL, GND, XTAL) Pin Spacing – 0.1" (2.54 mm), breadboard compatible Ideal For Arduino-compatible breadboard builds (ATmega328P at 16 MHz) General-purpose microcontroller clock source UART and serial baud rate generation Package Contents 1× 16 MHz ceramic resonator
