B39242B7509L210

Overview

The B39242B7509L210 is a Surface Acoustic Wave (SAW) RF filter manufactured by Qualcomm. It operates at a center frequency of 2.442GHz with a bandwidth of 79MHz and an insertion loss of 2.5dB. The component is housed in a compact 5-SMD, No Lead package measuring 1.40mm x 1.10mm x 0.70mm. Designed for Bluetooth applications, it supports surface mount installation and complies with RoHS3 standards.

Feature Summary

• Utilizes Surface Acoustic Wave technology for RF filtering
• Optimized for Bluetooth communication bands
• Compact 5-SMD leadless package design

Applications

• Bluetooth wireless connectivity modules
• RF front-end signal processing
• Mobile device radio frequency circuits

Procurement Notes

Verify the specific suffix L210 against official Qualcomm documentation to confirm exact electrical tolerances and marking revisions. Ensure compatibility with existing PCB footprint dimensions, particularly the 1.40mm x 1.10mm outline. Confirm moisture sensitivity level (MSL 3) handling requirements during assembly to prevent package damage.

Selection Notes

Select this component when a 2.442GHz center frequency with 79MHz bandwidth is required for Bluetooth applications. The 5-SMD no-lead package suits space-constrained designs. Compare insertion loss specifications against system link budget requirements. Verify that the 2.5dB loss meets performance thresholds for the intended RF chain configuration.
