402F50012IKR

Crystals Overview

The CTS-Frequency Controls 402F50012IKR is a surface-mount MHz crystal operating at a fundamental frequency of 50.0000 MHz. It features a load capacitance of 8pF and an equivalent series resistance (ESR) of 60 Ohms. The component offers a frequency tolerance of ±10ppm and stability of ±20ppm. Housed in a compact 4-SMD, No Lead package measuring 2.00mm x 1.60mm with a maximum height of 0.55mm, it supports base harmonic operation within a temperature range of -40°C to 85°C.

Crystals Feature Summary

• Compact surface-mount design suitable for space-constrained PCB layouts
• Fundamental mode operation ensures stable frequency generation
• Compliant with RoHS3 standards for environmental safety

Crystals Applications

• Microcontroller clock sources
• Communication module timing circuits
• Digital signal processing systems

Crystals Procurement Notes

Verify the specific suffix IKR against official datasheets to confirm package dimensions and lead configuration. Ensure compatibility with existing PCB footprints, as the 4-SMD No Lead form factor requires precise solder paste application. Confirm that the 8pF load capacitance matches the target oscillator circuit requirements to maintain specified frequency accuracy.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency is required with tight ±10ppm tolerance. The 8pF load capacitance dictates circuit matching; verify host oscillator parameters before integration. Consider the 60 Ohm ESR for drive level sensitivity. The wide temperature range supports industrial applications requiring reliability under thermal variation.
