About this product
A 16 MHz three-pin ceramic resonator used as a clock source for microcontrollers and digital circuits. It is less precise than a quartz crystal, so it suits applications where moderate timing accuracy is acceptable. Although the listing calls it an oscillator, it is a resonator and needs a compatible oscillator circuit in the MCU or external circuitry.

Frequently asked questions
How do I wire a 3-pin resonator to a microcontroller?
The two outer pins normally connect to the MCU's oscillator input and output pins (such as XIN and XOUT), and the middle pin goes to ground. Many 3-pin ceramic resonators have built-in load capacitors, but confirm this in the datasheet of your exact part because some variants require external capacitors.
Can I use it to replace a crystal of a different frequency?
Only if the MCU and its firmware are configured for 16 MHz. A different clock frequency changes timing, such as UART baud rates and delays, so the firmware clock settings must match. Ceramic resonators are less accurate than crystals, so avoid them in precision timing applications.
