Quartz crystals in the low-profile HC-49/S can, two leads, for setting the clock frequency of a microcontroller or timing circuit. Pick 16 MHz for an ATmega or Arduino build, 20 MHz to run a PIC at full speed, 8 MHz where you want lower power, or the kHz values for real-time-clock and slow timing work. Remember a crystal is passive: it needs the oscillator built into your chip plus two small load capacitors (typically 18-22 pF) to ground, and has no supply pin of its own.
Key features
- Frequencies stocked: 12 kHz, 32 kHz, 8, 16 and 20 MHz
- Two-lead through-hole quartz crystal
- 16 MHz suits an ATmega, 20 MHz a PIC at full speed
- Passive - pair it with two 18-22 pF load capacitors
- Far more accurate than an RC or internal oscillator
- Not an oscillator module - there is no power pin
