About this product
Two-pin passive quartz crystal rated 22.118 MHz, in an 11.1 x 4.7 x 2.5 mm housing. This frequency is often chosen for exact UART baud-rate timing. It needs an external oscillator circuit with load capacitors.

Frequently asked questions
Why is 22.118 MHz used in some projects?
Its value allows standard UART baud rates to be generated with very little timing error when the microcontroller uses it as the clock source. Confirm the value against your MCU's clock and baud-rate settings.
Does it need load capacitors?
Usually yes. Connect it to the MCU oscillator pins with load capacitors as specified in the MCU datasheet, since a passive crystal does not oscillate alone.
