FAR-F5KB-836M50-B4ER-Z

Overview

The FAR-F5KB-836M50-B4ER-Z is a Surface Acoustic Wave (SAW) filter manufactured by Taiyo Yuden. It operates at a center frequency of 836.5 MHz with a bandwidth of 25 MHz, designed for Band 5 Rx applications in mobile devices. The component features a 5-pin SMD package with dimensions of 1.40mm x 1.00mm x 0.50mm. Key electrical characteristics include an insertion loss of 1.6 dB and attenuation of 42 dB. It supports W-CDMA/CDMA systems and utilizes reflow soldering.

Feature Summary

• Low insertion loss for efficient signal transmission
• High attenuation to minimize interference
• Compact surface mount package design

Applications

• Cellular communication modules
• CDMA network devices
• Mobile phone RF front ends

Procurement Notes

Verify the specific suffix 'B4ER' against official Taiyo Yuden documentation to confirm exact pinout and termination specifications. Confirm current availability status as some sources indicate discontinued or non-preferred status. Ensure compatibility with W-CDMA/CDMA system requirements before procurement.

Selection Notes

Select this component for applications requiring precise filtering at 836.5 MHz within the 25 MHz bandwidth. Consider the small 1.40x1.00mm footprint for space-constrained designs. Verify that the 1.6 dB insertion loss meets system sensitivity requirements and that the 42 dB attenuation satisfies interference suppression needs.

Part Context

This part belongs to the F5 series of SAW filters from Taiyo Yuden. It is specifically engineered for Band 5 receive paths in mobile handsets. The device integrates acoustic wave technology to provide sharp frequency selectivity essential for modern cellular standards.

Replacement Considerations

Check for direct substitutes within the same F5 series or equivalent SAW filters from other manufacturers offering identical 836.5 MHz center frequency and 5-SMD package dimensions. Ensure functional equivalence in terms of insertion loss and attenuation specs.
