RF1401D

Overview

The Murata Electronics RF1401D is a Surface Acoustic Wave (SAW) filter designed for wireless applications. It operates at a center frequency of 433.92 MHz with a bandwidth of 1 MHz and an insertion loss of 2.8 dB. The component utilizes an advanced Lithium Tantalate (LiTaO3) design to achieve low insertion loss. It is housed in an 8-SMD, no-lead package measuring 3.80mm x 3.80mm with a maximum height of 1.40mm. The device is qualified under AEC-Q200 standards and complies with RoHS3 specifications.

Feature Summary

• Advanced Lithium Tantalate (LiTaO3) construction for low insertion loss
• Narrowband receiver front-end capability
• AEC-Q200 qualification

Applications

• Wireless RF systems
• 433.92 MHz narrowband receiver front ends

Procurement Notes

Verify the current manufacturing status before procurement as the RF1401D has been reported as obsolete or end-of-life by multiple distributors. Confirm availability through authorized channels or identify suitable replacement components if active sourcing is required. Ensure that any substitute parts meet the specific electrical requirements of the original design.

Selection Notes

Select this component for designs requiring a SAW filter at 433.92 MHz with strict size constraints due to its compact 8-SMD package. Consider the AEC-Q200 qualification if automotive reliability standards are necessary. Evaluate the 2.8 dB insertion loss against system link budget requirements. Verify compatibility with surface mount assembly processes given the no-lead package type.
