ECS-10.7-30B

Overview

The ECS-10.7-30B is a monolithic crystal filter manufactured by ECS Inc., designed for intermediate frequency applications. It operates at a center frequency of 10.7 MHz with a bandwidth of 30 kHz. The component features four poles and exhibits an insertion loss of 2.5 dB. It is housed in an HC-49/U x2 through-hole package, suitable for standard PCB mounting. The device supports an operating temperature range from -20°C to 70°C.

Feature Summary

• Monolithic construction providing stable intermediate frequency filtering
• Four-pole design for improved selectivity
• Through-hole mounting capability in HC-49/U form factor

Applications

• Intermediate frequency filtering in radio receivers
• Communication equipment signal processing
• Audio frequency demodulation circuits

Procurement Notes

Verify the specific suffix 'B' against official ECS documentation to confirm exact electrical tolerances and physical dimensions. Ensure the HC-49/U x2 footprint matches your PCB layout requirements. Confirm the operating temperature range meets your environmental specifications before finalizing procurement decisions.

Selection Notes

Select this component when a 10.7 MHz center frequency with 30 kHz bandwidth is required for IF stages. The four-pole configuration offers better shape factor than two-pole alternatives. Consider the through-hole package constraint and verify that the -20°C to 70°C range aligns with your system's thermal environment.

Part Context

This part belongs to the ECS monolithic crystal filter series, which utilizes ceramic or quartz technology for precise frequency selection. These filters are commonly used in analog communication systems where sharp cutoff characteristics are necessary to reject adjacent channel interference while passing the desired signal band.

Replacement Considerations

Check for direct substitutes with identical 10.7 MHz center frequency and 30 kHz bandwidth. Verify pole count and insertion loss specifications match to maintain circuit performance. Ensure mechanical compatibility with the HC-49/U x2 package before considering alternative manufacturers.
