A 12MHz quartz crystal resonator providing a stable reference clock for MCU and communication timing. Available in common SMD and through-hole packages, it is a foundational timing component for embedded designs.
Product Overview
This 12MHz quartz crystal is a passive timing element that, together with the on-chip oscillator circuit of a microcontroller or clock generator, establishes a precise reference frequency. Crystals are preferred over RC oscillators where frequency accuracy, stability, and low jitter are required.
The 12MHz frequency is widely used across MCU clock trees, USB-related timing, and general-purpose digital logic. Newfly supplies verified crystals in industry-standard footprints to simplify drop-in placement and second-source qualification.

FAQ
Q: Is this an active oscillator or a passive crystal?
A: It is a passive quartz crystal resonator that works with the oscillator circuit inside your MCU or clock IC. If you need a self-contained clock, request an active crystal oscillator module instead.
Q: How do I select the load capacitance?
A: The crystal’s rated load capacitance must be matched by the external load capacitors in your circuit; confirm the exact value in the manufacturer datasheet.
Q: Can you supply different packages?
A: Yes. Common SMD (e.g., 3225, 2520) and through-hole (HC-49S) footprints are available; specify your required package when ordering.
