Crystal Resonator 1MHz

The Crystal Resonator 1MHz is a two-terminal passive quartz crystal that resonates at 1 MHz. Paired with an oscillator circuit, such as the one built into most microcontrollers or a simple inverter-gate circuit, it produces a clock signal that is far more stable and accurate than an RC oscillator. The low 1 MHz frequency suits slow, low-power clocks and timing references that are easy to divide down.

Crystal Resonator 1MHz Specifications

• Frequency: 1 MHz
• Type: quartz crystal resonator, passive, two terminals
• Polarity: none, can be fitted either way round
• Load capacitors: usually one small capacitor from each pin to GND; use the value your oscillator circuit needs
• Pack size: 1 piece

Crystal Resonator 1MHz Applications

• Low-speed clock for PIC and other microcontrollers
• Crystal oscillators built with CMOS inverter gates such as the 74HC04 or CD4069
• Frequency reference for counters and dividers
• Checking and calibrating frequency meters
• Electronics labs on oscillators

What's in the Box

• 1 × 1 MHz crystal

Tip: Keep the crystal and its two load capacitors close to the oscillator pins, with short leads, to avoid start-up problems. On a PIC microcontroller, choose the XT oscillator mode for a 1 MHz crystal.
