0900FM15K0039001E

Overview

The Johanson Technology Inc. 0900FM15K0039001E is a surface-mount ceramic bandpass filter designed for RF applications. It operates with a center frequency of 895 MHz and provides a bandwidth of 66 MHz. The component features a 50-ohm impedance and an insertion loss of 2 dB. It is housed in a compact 0805 (2012 metric) package, measuring 2.00 mm in length, 1.25 mm in width, and 0.80 mm in maximum height.

Feature Summary

• Integrated passive component design optimized for specific transceiver compatibility
• Impedance-matched architecture eliminating external matching networks
• Miniature surface-mount form factor for space-constrained layouts

Applications

• Semtech SX1261 transceiver circuits
• Semtech SX1262 transceiver circuits
• Semtech LLCC68 module integration

Procurement Notes

Verify the exact suffix '001' against the manufacturer's current datasheet to confirm pinout and electrical specifications. Ensure the ordering quantity aligns with standard reel sizes. Confirm RoHS3 compliance status if required by specific regional regulations before finalizing procurement.

Selection Notes

Select this component when designing for 868 MHz or 915 MHz ISM bands using Semtech chips. The integrated nature reduces board space compared to discrete LC filters. Verify that the 2 dB insertion loss meets system link budget requirements. Ensure the 0805 footprint matches the PCB land pattern.

Part Context

This part belongs to Johanson Technology's family of miniature impedance-matched filters. These components are engineered as integrated passive devices (IPCs) to simplify RF front-end designs. They replace multiple discrete components, offering a standardized solution for specific wireless communication protocols.

Replacement Considerations

The legacy part number 0900FM15D0039 may serve as a reference, but verify functional equivalence. Check datasheets for differences in center frequency tolerance and package dimensions before substituting.
