ECS-D479.5B

Overview

The ECS-D479.5B is a Surface Acoustic Wave (SAW) bandpass filter designed for RF applications. It operates at a center frequency of 479.5 MHz with a bandwidth of 2 MHz and provides 23 dB insertion loss. The component utilizes a TO-205AD (TO-39-3) metal can package, featuring a diameter of 9.50 mm and a maximum height of 3.50 mm. This through-hole device is engineered for satellite receiver systems.

Feature Summary

• Surface Acoustic Wave technology for precise signal filtering
• Metal can construction for shielding and durability
• Through-hole mounting capability

Applications

• Satellite TV receivers
• RF signal conditioning in satellite communication equipment

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and pinout configurations before integration. Ensure the TO-39-3A package dimensions align with the PCB footprint requirements. Confirm that the 23 dB insertion loss meets the system link budget constraints for the intended satellite receiver application.

Selection Notes

Select this component when a fixed 479.5 MHz center frequency is required for satellite downlink processing. The TO-39-3 metal package offers robust mechanical stability compared to ceramic alternatives. Consider the 2 MHz bandwidth relative to the signal spectrum width to ensure adequate adjacent channel rejection without distorting the desired signal.

Part Context

This part belongs to the ECS Inc. SAW filter family, which specializes in discrete RF components for broadcast and communication markets. The TO-39-3A package is a standard hermetic metal case often used in military and aerospace-grade electronics due to its reliability and shielding properties against electromagnetic interference.

Replacement Considerations

Cross-reference with other 479.5 MHz SAW filters from manufacturers like Murata or TDK if supply chain constraints exist. Verify that substitute parts maintain the same TO-39-3 form factor and 2 MHz bandwidth specifications to ensure compatibility with existing satellite receiver circuit boards.
