BK1608LL431-T

Overview

The BK1608LL431-T is a multilayer chip bead inductor from the Taiyo Yuden BK series, designed for surface mount applications. It features an impedance of 430 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 200 mA and has a maximum DC resistance of 1.2 Ohms. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 1.6 mm in length, 0.8 mm in width, and 0.95 mm in height, conforming to the 0603 (1608 metric) package.

Feature Summary

• Multilayer construction for compact surface mount integration
• High impedance characteristic for effective noise suppression
• Automotive qualification compliant design

Applications

• Consumer electronics noise filtering
• Automotive system signal protection
• Industrial equipment EMI suppression

Procurement Notes

Verify the active lifecycle status directly with Taiyo Yuden or authorized distributors before procurement. Confirm that the specific suffix matches the required impedance and tolerance specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Check for any recent product discontinuance notifications or alternative part recommendations from the manufacturer.

Selection Notes

Select this component when a 430 Ohm impedance at 100 MHz is required for high-frequency noise attenuation. The 0603 package size suits space-constrained designs. Verify that the 200 mA current rating meets the circuit's DC load requirements. Consider the -55°C to +125°C operating range for environmental suitability. Compare against other BK series variants if different impedance or current characteristics are needed.

Part Context

This ferrite bead belongs to the BK series of multilayer chip bead inductors by Taiyo Yuden. The series offers various impedance values and package sizes for general-purpose noise suppression. The BK1608LL431-T specifically targets applications requiring moderate current handling with high impedance in a standard 0603 footprint.
