ECS-10.7-7.5B

Overview

The ECS-10.7-7.5B is a monolithic crystal filter manufactured by ECS Inc., designed for through-hole mounting. It operates at a center frequency of 10.7 MHz with a bandwidth of 7.5 kHz. The component features an impedance of 1.8 kOhms and an insertion loss of 2.5 dB. It is housed in a package measuring 11.10 mm x 4.70 mm and functions within an operating temperature range of -20°C to 70°C.

Feature Summary

• Monolithic crystal construction for stable filtering performance
• Through-hole mounting configuration
• Optimized for 10.7 MHz intermediate frequency applications

Applications

• FM radio receiver circuits
• Intermediate frequency (IF) filtering stages
• Communication equipment signal processing

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's current datasheet to confirm pinout and mechanical dimensions, as suffixes often denote packaging or tolerance variations. Ensure the 1.8 kOhm impedance matches your circuit design requirements before procurement. Cross-reference the 7.5 kHz bandwidth specification with system sensitivity needs.

Selection Notes

Select this component when a 10.7 MHz center frequency with narrow 7.5 kHz bandwidth is required for IF applications. The 1.8 kOhm impedance must align with source and load impedances to minimize reflection losses. Consider the -20°C to 70°C operating range for environmental suitability. The through-hole package dictates PCB layout constraints compared to surface-mount alternatives.

Part Context

This part belongs to the ECS monolithic crystal filter family, specifically engineered for fixed-frequency applications. These filters integrate multiple resonators into a single ceramic package to achieve steep skirt selectivity. The 10.7 MHz designation indicates its primary use in FM demodulation stages where precise frequency discrimination is critical for audio fidelity.

Replacement Considerations

Check for direct substitutes from ECS such as the ECS-10.7-7.5A, verifying if the suffix change impacts electrical parameters or packaging. Other manufacturers may offer equivalent 10.7 MHz filters, but impedance and bandwidth matching are essential for functional interchangeability without circuit modification.
