CFUMT6-38.805-F07IL02A

Overview

The CFUMT6-38.805-F07IL02A is a monolithic crystal filter manufactured by Suzhou Hangjing Elec & Tech Co., Ltd. It operates at a center frequency of 38.805 MHz with a 6 pF load capacitance. The device utilizes a through-hole mounting style and features an impedance of 1.5 kOhms. Key electrical specifications include a maximum insertion loss of 2 dB, a ripple of 1 dB, a 3 dB passband width of 7.5 kHz, and a stopband bandwidth of less than or equal to ±60 kHz at 40 dB attenuation. The component is designed for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Monolithic construction for stable signal filtering
• Through-hole package for reliable board integration
• Defined impedance matching at 1.5 kOhms

Applications

• RF signal processing circuits
• Communication equipment intermediate frequency stages
• Frequency selection in electronic systems

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact mechanical dimensions and terminal configurations. Ensure compatibility with existing PCB footprints and thermal management requirements. Confirm that the operating environment remains within the specified -40°C to +85°C range to maintain performance integrity. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a precise 38.805 MHz filtering solution with low insertion loss is required. Consider the through-hole format if automated surface-mount assembly is not available. Evaluate the 1.5 kOhm impedance against circuit source and load requirements. Verify that the narrow passband characteristics align with the system's bandwidth needs.
