DIP Quartz Crystal Oscillators Resonators 16MHz
= Through-Hole Timing Components for Microcontrollers and Digital Circuits =
16MHz quartz crystal resonators in DIP packages provide the stable clock signals needed for microcontroller operation and frequency generation. The 16MHz frequency is commonly used with Arduino boards and many other microcontrollers.
Stable Frequency Reference - ±20ppm to ±50ppm accuracy for reliable timing
ThroughHole DIP Package Easy breadboard and PCB mounting
Available in HC49S (2pin) and metal DIP (4-pin) packages
2-pin passive crystals require external load capacitors (typically 20pF)
Active crystal oscillators (4-pin) are powered devices that output a square wave
