CFMH4-1.400-F02IL02LSBK

Overview

The CFMH4-1.400-F02IL02LSBK is a crystal filter manufactured by Suzhou Hangjing Elec&Tech Co.,Ltd. It operates at a center frequency of 1.4 MHz with a bandwidth of 2 kHz. The component features four poles and utilizes a through-hole mounting type in a 4-DIP module package with four leads. Physical dimensions are specified as 0.433 inches in length, with overall measurements of 76.2 mm x 26.9 mm x 22.5 mm. The insertion loss is rated at 6 dB.

Feature Summary

Four-pole crystal filter design for precise frequency selection
Through-hole DIP packaging for reliable board integration
Certified to ROHS standards for environmental compliance

Applications

Intermediate frequency filtering in communication receivers
Signal processing circuits requiring narrow bandwidth selection
Quartz frequency control unit assemblies

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure exact electrical characteristics match system requirements. Confirm that the 4-DIP package dimensions align with PCB footprint constraints. Check for current ISO management certification status if required by quality protocols. Ensure the component meets all applicable ROHS directives before final procurement approval.

Selection Notes

Select this component when a 1.4 MHz center frequency with 2 kHz bandwidth is required. The four-pole configuration provides necessary selectivity for intermediate frequency applications. Consider the physical size of the 4-DIP module during layout planning. Verify compatibility with through-hole assembly processes and ensure the 6 dB insertion loss fits within the system's power budget.
