BPF1005LRQLR4700A

Overview

The BPF1005LRQLR4700A is a bandpass filter manufactured by Pulse Electronics, designed for signal conditioning and EMI/RFI suppression. It operates within a passband of 4400 MHz to 5000 MHz with a center frequency of 4.7 GHz. The component features a 50 Ohm impedance and utilizes an SMD/SMT termination type in a compact 0402 (1005 metric) package. It supports board mounting and functions reliably across a temperature range of -40°C to +85°C. The device exhibits an insertion loss of 1.74 dB and is part of the BPF series, specifically identified as Type LR.

Feature Summary

• Provides effective EMI and RFI suppression for signal integrity
• Utilizes LTCC technology for compact surface-mount integration
• Maintains stable performance across industrial temperature ranges

Applications

• Wireless robotics communication systems
• RF signal filtering in mobile devices
• EMI suppression in high-frequency circuit boards

Procurement Notes

Verify the specific suffix 'LR' against official datasheets to confirm the exact electrical characteristics, as variations exist within the BPF family. Ensure compatibility with standard SMT reflow processes for the 0402 package. Confirm RoHS compliance status through current manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when a narrow bandpass filter is required for the 4.4-5.0 GHz range in space-constrained designs. The 0402 footprint offers a balance between performance and board real estate. Consider the 1.74 dB insertion loss impact on system gain. Verify that the 50 Ohm impedance matches the surrounding RF trace requirements.

Part Context

This component belongs to Pulse Electronics' BPF series of LTCC bandpass filters. These components are engineered for high-frequency applications requiring precise frequency selection. The 1005 metric size indicates a small form factor suitable for modern dense PCB layouts. The product line focuses on providing reliable signal conditioning for wireless technologies.

Replacement Considerations

Check for direct substitutes within the same BPF series with identical 0402 footprints and similar passband specifications. Ensure any replacement maintains the 50 Ohm impedance and compatible operating temperature range. Verify pinout and mechanical dimensions if substituting with components from other manufacturers.
