ECS-10.7-30A

Overview

The ECS-10.7-30A is a monolithic crystal filter manufactured by ECS Inc., designed for signal conditioning applications. It operates at a center frequency of 10.7 MHz with a bandwidth of 30 kHz. The component features an impedance of 5 kΩ and an insertion loss of 1.5 dB. It utilizes a two-pole configuration and exhibits a ripple of 0.5 dB. The device is housed in an HC-49/U package, measuring 11.10mm x 4.70mm, and supports through-hole mounting. It functions within an operating temperature range of -20°C to 70°C.

Feature Summary

• Monolithic crystal construction for stable signal filtering
• Two-pole design with low insertion loss characteristics
• Through-hole mounting capability in standard HC-49/U package

Applications

• Intermediate frequency (IF) filtering in radio receivers
• Signal conditioning in communication equipment
• Audio processing circuits requiring specific frequency selection

Procurement Notes

Verify the exact part number suffix against official ECS Inc. documentation to ensure correct specifications. Confirm that the required impedance, bandwidth, and package type match your circuit design requirements before ordering. Check for any recent manufacturing updates or obsolescence notices directly from the manufacturer or authorized distributors to avoid supply chain disruptions.

Selection Notes

Select this component when a 10.7 MHz center frequency with a 30 kHz bandwidth is required. Ensure the system impedance matches the 5 kΩ specification to minimize reflection losses. Consider the HC-49/U package dimensions for PCB layout constraints. Verify that the operating temperature range meets the environmental conditions of the final application.

Part Context

This component belongs to the family of monolithic crystal filters produced by ECS Inc. These devices are engineered for precise frequency selection in analog and digital signal processing systems. The HC-49/U package is a widely used standard for through-hole crystal components, offering mechanical robustness and ease of integration into printed circuit boards for various electronic assemblies.

Replacement Considerations

The ECS-10.7-30B is a related variant with different specifications, including a four-pole design and 2.5 dB insertion loss. Direct substitution requires verifying compatibility with the target circuit's impedance and bandwidth requirements. Other manufacturers may offer equivalent parts, but pinout and electrical parameters must be cross-referenced carefully.
