BLF02RD471GNED

Chip Ferrite Bead Overview

The Murata BLF02RD471GNED is a single-channel ferrite bead chip filter designed for surface-mount applications. It operates within the BLF series and utilizes an 01005 (0402 metric) package with dimensions of 0.4 mm in length, 0.2 mm in width, and 0.3 mm in height. The component provides an impedance of 470 ohms at a test frequency of 2.4 GHz. It supports a maximum DC current of 200 mA and exhibits a maximum DC resistance of 900 milliohms. The device functions reliably across a temperature range from -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• High-impedance RF noise filtering capability specifically optimized for the 2.4 GHz frequency band.
• Ultra-compact 01005 surface-mount footprint suitable for space-constrained circuit board layouts.
• Robust thermal stability ensuring consistent performance across extended industrial temperature ranges.

Chip Ferrite Bead Applications

• Noise suppression in wireless communication modules operating at 2.4 GHz.
• Signal integrity enhancement in compact mobile electronic devices.
• RF interference mitigation in high-density printed circuit board designs.

Chip Ferrite Bead Procurement Notes

Verify the specific ordering suffix against official Murata documentation to ensure correct impedance and tolerance specifications. Confirm RoHS compliance status through authorized distributors. Cross-reference the Mouser part number 81-BLF02RD471GNED for accurate sourcing. Ensure the selected variant matches the required 01005 package dimensions for your PCB layout constraints.

Chip Ferrite Bead Selection Notes

Select this component when designing circuits requiring precise attenuation at 2.4 GHz with minimal physical footprint. The 200 mA current rating suits low-power signal lines rather than high-current power rails. Consider the 900 mOhm DC resistance impact on signal loss. The wide operating temperature range makes it suitable for diverse environmental conditions without derating concerns.

Chip Ferrite Bead Part Context

This ferrite bead belongs to Murata's BLF series, which focuses on high-frequency noise suppression. Unlike general-purpose beads, this model targets specific RF bands. It differs from larger packages like the BLM41PG by offering significantly reduced parasitic effects due to its smaller size. The BLF series is engineered for modern miniaturized electronics where space is critical.
