RF1400D

Overview

The Murata Electronics RF1400D is a Surface Acoustic Wave (SAW) filter designed for wide channel applications. It operates at a center frequency of 433.92 MHz with a bandwidth of 1.15 MHz and an insertion loss of 2 dB. The component is housed in an 8-SMD, no-lead package measuring 3.80 mm x 3.80 mm with a maximum height of 1.40 mm. It is RoHS3 compliant and classified under ECCN EAR99.

Feature Summary

• Surface Acoustic Wave technology for signal conditioning
• Optimized for wide channel RF applications
• Compact surface mount construction

Applications

• Wide channel receiver front ends
• RF signal filtering systems

Procurement Notes

Verify current availability as the RF1400D is officially discontinued by Murata Electronics. Confirm that replacement components meet all original electrical specifications, including center frequency, bandwidth, and physical footprint requirements. Ensure compatibility with existing PCB layouts and assembly processes when transitioning to substitute parts.

Selection Notes

Select this component for designs requiring a 433.92 MHz SAW filter with specific 1.15 MHz bandwidth characteristics. Consider the 8-SMD package dimensions for space-constrained layouts. Evaluate alternative sources or equivalent models due to the part's end-of-life status and potential supply chain constraints.

Part Context

The RF1400D belongs to the RF14 series of SAW filters manufactured by Murata Electronics. It serves as a specialized passive component for radio frequency signal processing, providing frequency selection capabilities within narrow bands around the 433.92 MHz ISM band.

Replacement Considerations
