BK1005HM471-T

Overview

The BK1005HM471-T is a multilayer chip ferrite bead manufactured by Taiyo Yuden in the BK series. It features a 0402 (1005 metric) surface-mount package with SMD/SMT termination. The component provides an impedance of 470 ohms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 250 mA and has a maximum DC resistance of 450 milliohms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• Provides electromagnetic interference and radio frequency interference suppression in electronic circuits
• Utilizes multilayer chip bead technology for compact noise filtering
• Designed for high-temperature stability within specified industrial ranges

Applications

• EMI/RFI suppression in general electronic circuits
• Noise filtering for signal lines requiring compact form factors
• Power line filtering for low-current applications

Procurement Notes

Verify component availability as the lifecycle status is listed as End-of-Life or obsolete. Confirm RoHS compliance details through official documentation before integration. Ensure design-in processes account for potential supply chain discontinuation risks associated with discontinued part numbers.

Selection Notes

Select this component for applications requiring 470 ohm impedance at 100 MHz in a 0402 footprint. Verify that the 250 mA current rating meets circuit requirements. Consider alternative active parts if long-term supply continuity is critical, given the obsolete status.

Part Context

This ferrite bead belongs to Taiyo Yuden's BK series of multilayer chip beads. These components are engineered for noise suppression in portable devices and industrial electronics. The 0402 size offers space-saving benefits for dense PCB layouts while maintaining effective high-frequency attenuation characteristics.
