RFBPF2012080AFT

Overview

The RFBPF2012080AFT is a surface-mount bandpass filter manufactured by Walsin Technology Corporation. Designed for EMI and RFI suppression, this component operates at a center frequency of 2.45 GHz with a bandwidth of 2 dB. It features an insertion loss of 2 dB and maintains a 50 Ohm impedance. The device utilizes a 0603 (1608 metric) package size, making it suitable for compact electronic designs requiring reliable signal conditioning in the 2.4 GHz ISM band.

Feature Summary

• Provides effective EMI and RFI suppression for sensitive RF circuits
• Optimized for operation within the 2.4 GHz industrial, scientific, and medical band
• Utilizes a compact 0603 surface mount footprint for space-constrained layouts

Applications

• Wireless LAN modules operating in the 2.4 GHz spectrum
• Bluetooth devices requiring interference filtering
• Zigbee and other 2.4 GHz wireless communication interfaces

Procurement Notes

Verify the specific datasheet revision to confirm electrical characteristics match design requirements. Ensure the 0603 package dimensions align with PCB land pattern specifications. Confirm RoHS compliance status if required by project regulations. Validate that the 2.45 GHz center frequency suits the target application's channel plan.

Selection Notes

Select this component when a low-profile solution is needed for 2.4 GHz signal integrity. The 0603 case size offers a balance between performance and board real estate. Consider the 2 dB insertion loss impact on link budget calculations. Ensure the 50 Ohm system impedance matches the surrounding circuitry to minimize reflections.

Part Context

This part belongs to Walsin's RFBPF series of RF bandpass filters. These components are engineered for high-reliability applications in consumer electronics and telecommunications. The series provides standardized solutions for common wireless frequencies, simplifying the design process for manufacturers developing compact wireless devices.

Replacement Considerations

Check for direct pin-compatible alternatives from Walsin or other suppliers offering identical 2.45 GHz center frequency and 0603 package dimensions. Verify that substitute parts maintain the same 50 Ohm impedance and insertion loss characteristics to ensure circuit compatibility.
