TFSB10055375-1103A1

Overview

The TFSB10055375-1103A1 is a passive thin-film bandpass RF filter manufactured by TDK Corporation. It operates at a center frequency of 5375 MHz with an insertion loss of 0.9 dB. The component utilizes a surface-mount 0402 (1.00mm x 0.50mm) package with a maximum height of 0.40mm. This device is designed for high-frequency signal processing applications, offering precise filtering characteristics within a compact footprint suitable for dense circuit layouts.

Feature Summary

• Thin-film construction ensures stable performance in high-frequency environments
• Bandpass topology isolates specific frequency bands while attenuating out-of-band signals
• Compact 0402 surface-mount package facilitates automated assembly and space-constrained designs

Applications

• Mobile phone signal integrity enhancement
• Wireless LAN module filtering
• Bluetooth module signal conditioning

Procurement Notes

Verify product status as obsolete before procurement planning. Confirm last purchase order dates and availability through authorized channels. Ensure replacement strategies are established due to discontinuation. Validate RoHS compliance and lead-free specifications against current regulatory requirements. Cross-reference datasheet revisions to confirm technical consistency.

Selection Notes

Select this component only if the 5375 MHz center frequency matches system requirements. Evaluate the 0.9 dB insertion loss impact on overall link budget. Consider the 0402 package dimensions for PCB layout constraints. Assess supply chain risks associated with obsolete status and potential long-term sourcing challenges.
