AFS374E

Overview

The AFS374E is a Surface Acoustic Wave (SAW) filter manufactured by Abracon LLC, designed for radio frequency applications. It operates at a center frequency of 374 MHz with a bandwidth of 20.5 MHz. The component exhibits an insertion loss of 8.5 dB and is housed in an 8-SMD package without lead, measuring 5 x 5 x 1.35 mm. This device is specifically engineered for WLAN systems, providing signal filtering capabilities within the specified frequency range.

Feature Summary

• Utilizes Surface Acoustic Wave technology for RF signal processing
• Optimized for WLAN application environments
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• Wireless Local Area Network (WLAN) systems
• RF signal filtering in communication devices
• Frequency selection circuits operating near 374 MHz

Procurement Notes

Verify part authenticity through official Abracon channels or authorized distributors. Confirm RoHS compliance status and lead-free specifications prior to ordering. Check for obsolete status indicators as availability may be limited. Ensure packaging matches engineering requirements for SMD handling. Validate datasheet revisions against current production versions to guarantee technical accuracy.

Selection Notes

Select this component when a 374 MHz center frequency with 20.5 MHz bandwidth is required for WLAN designs. Consider the 8.5 dB insertion loss impact on system sensitivity. Evaluate the 8-SMD footprint compatibility with existing board layouts. Assess thermal performance within the 5x5x1.35mm package constraints. Verify operational temperature ranges against application specifications.

Part Context

The AFS374E belongs to Abracon's SAW filter series, targeting specific frequency bands for wireless communications. It complements other RF components in signal chain architectures. The 8-SMD package facilitates automated assembly processes. This model represents a specialized solution for mid-band WLAN frequencies, distinct from broadband or multi-standard filters.

Replacement Considerations

Public confirmed substitute part numbers are not available in verified documentation. Consult Abracon directly for obsolescence management or equivalent alternatives. Cross-reference electrical parameters carefully if considering generic replacements.
