EFCH881MTCA1

Overview

The EFCH881MTCA1 is a Surface Acoustic Wave (SAW) filter manufactured by Panasonic Electronic Components. It operates at a center frequency of 881.5 MHz and is housed in a 5-SMD surface-mount package. This component is designed for RF signal processing applications, specifically targeting cellular phone radio frequency circuits where precise frequency selection and interference rejection are required.

Feature Summary

• Utilizes Surface Acoustic Wave technology for efficient RF filtering
• Designed for compact surface-mount integration
• Optimized for cellular communication frequency bands

Applications

• Cellular phone RF front-end modules
• Wireless communication device signal conditioning
• RF interference suppression circuits

Procurement Notes

Verify the specific suffix 'A1' against official Panasonic documentation to confirm pinout and electrical characteristics, as suffixes often denote tape-and-reel packaging or specific manufacturing revisions. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as public listings may contain conflicting environmental compliance data. Ensure the source document matches the exact part number to avoid substitution errors with similar variants like EFCH881MTCD1.

Selection Notes

Select this component when a SAW filter is required for the 881.5 MHz band in mobile telecommunications equipment. The 5-SMD package facilitates automated assembly in compact PCB layouts. Engineers should verify that the filter's insertion loss and bandwidth specifications meet the system's link budget requirements before finalizing the design.

Part Context

This component belongs to the Panasonic SAW filter series, which provides passive RF filtering solutions for wireless devices. These filters are critical for isolating desired signals from noise and adjacent channel interference in mobile handsets and base stations, ensuring clear signal transmission and reception within regulated spectrum allocations.

Replacement Considerations

Public cross-reference data indicates EFCH881MTCD1 as a related variant. Verify if the 'D1' suffix denotes a different packaging type or electrical tolerance compared to the 'A1' version before substituting.
