Crystal Oscillator 16MHz

The Crystal Oscillator 16MHz is a 16 MHz quartz crystal used as a stable, accurate clock source for microcontrollers. 16 MHz is the clock speed of the Arduino Uno, Nano and Mega, so this is the crystal you need to build a standalone ATmega328P Arduino on a breadboard or your own Arduino-compatible PCB. With two small load capacitors it keeps time far more precisely than an internal RC oscillator.

Crystal Oscillator 16MHz Specifications

• Frequency: 16 MHz
• Type: quartz crystal, two-terminal (passive), driven by the microcontroller's oscillator circuit
• Load capacitors: typically 15–33 pF, commonly 22 pF, one from each pin to GND
• Polarity: none, can be fitted either way round

Crystal Oscillator 16MHz Applications

• Standalone ATmega328P and ATmega8 Arduino builds
• Custom Arduino-compatible and AVR boards
• PIC microcontrollers in HS oscillator mode
• Accurate timing for clocks, counters and serial communication
• Microcontroller and digital electronics labs

What's in the Box

• 1 × 16 MHz crystal

Tip: Connect the crystal between XTAL1 and XTAL2 (pins 9 and 10 on an ATmega328P DIP) with a 22 pF ceramic capacitor from each pin to GND, and keep the leads short. A new ATmega328P runs on its internal oscillator until you burn the Arduino bootloader or set the fuses for an external crystal.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
