This compact TCXO is a temperature-compensated crystal oscillator designed to provide a stable 26.0MHz reference in a tiny surface-mount footprint.
It uses a clipped sine wave output and runs from a 1.8V supply, making it suited to space-constrained RF, timing and embedded electronics designs that need good frequency stability across temperature.
The oscillator comes in a 1.65 x 1.25mm surface mount package for direct assembly onto a PCB. A datasheet is available from the manufacturer for footprint and integration details.

Jargon buster
Plain-language definitions for the technical terms used above.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
- Tolerance
- Tolerance tells you how far the real resistance value may be from the printed value. A 1% resistor is useful when a circuit needs more predictable behaviour than a looser 5% or 10% part.
