RFBPF2012040AB7B1U

Overview

The RFBPF2012040AB7B1U is a surface-mount bandpass RF filter manufactured by Walsin Technology Corporation. Designed for the 2.4 GHz ISM band, this component operates at a center frequency of 2.4 GHz with a 50 Ohm characteristic impedance. It utilizes a 0805 (2012 metric) package size, measuring 2.0 mm in length and 1.25 mm in width. The device features grounding through-holes to facilitate PCB integration and line width design matching the system impedance.

Feature Summary

• Bandpass filtering capability optimized for the 2.4 GHz ISM band
• Surface mount construction with grounding through-holes for board mounting
• Designed to match 50 Ohm characteristic impedance

Applications

• ISM band wireless communication systems
• Mobile communications devices
• Networking equipment signal conditioning

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Walsin Technology Corporation or authorized distributors before procurement. Confirm that the 0805 package dimensions and grounding via requirements align with your PCB layout constraints. Ensure the 50 Ohm impedance specification matches your circuit design requirements to prevent signal reflection issues.

Selection Notes

Select this component when a compact bandpass filter is required for 2.4 GHz applications. The 0805 footprint offers space efficiency compared to larger packages. Verify that the grounding through-hole design is compatible with your manufacturing process. Consider the insertion loss characteristics if detailed performance metrics are available in the official datasheet.
