B39431R0904U410

Overview

The B39431R0904U410 is a Surface Acoustic Wave (SAW) resonator manufactured by Qualcomm RF front-end filters. It operates at a center frequency of 433.42 MHz and utilizes a 6-SMD, No Lead package with dimensions of 3.00mm x 3.00mm. This component is designed for surface mount technology applications requiring precise frequency control in compact electronic designs.

Feature Summary

• Utilizes Surface Acoustic Wave (SAW) technology for stable frequency generation
• Compact 6-SMD no-lead package design suitable for space-constrained layouts
• Optimized for operation within standard industrial temperature ranges

Applications

• Remote control systems
• ISM band communication devices
• Portable consumer electronics

Procurement Notes

Verify the specific operating frequency of 433.42 MHz against your circuit requirements, as it differs from similar 433.92 MHz variants. Confirm the 6-SMD package compatibility with your PCB footprint. Ensure the manufacturer source is Qualcomm or an authorized distributor to guarantee component authenticity and performance specifications.

Selection Notes

Select this component when a SAW resonator is required specifically at 433.42 MHz rather than the more common 433.92 MHz. The choice depends on strict adherence to the 3x3mm form factor and the need for a low-profile SMD solution. Compare insertion loss and load capacitance requirements if integrating into existing filter-based architectures.

Part Context

This part belongs to the B39431 series of RF components from Qualcomm, which includes various SAW filters and resonators. It serves as a passive frequency-determining element within radio frequency front-end modules, distinct from active amplifiers or complex filter banks found in modern mobile handsets.

Replacement Considerations

B39431R806H210 is listed as an obsolete substitute option.
