BKH0603HL221-T

Chip Ferrite Bead Overview

The BKH0603HL221-T is a multilayer chip bead inductor from the BK series H type, manufactured by Taiyo Yuden. It features a 0201 (0603 metric) surface-mount package with dimensions of 0.6 mm length, 0.3 mm width, and 0.3 mm height. The component provides an impedance of 220 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 0.15 A and has a maximum DC resistance of 170 mOhms. The device operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Multilayer construction for high reliability in compact designs
• High current handling capability relative to package size
• Low DC resistance for minimal signal loss

Chip Ferrite Bead Applications

• Noise suppression in high-speed digital circuits
• Power line filtering in portable devices
• EMI suppression in RF modules

Chip Ferrite Bead Procurement Notes

Verify the specific suffix and packaging configuration directly with Taiyo Yuden or authorized distributors, as standard packaging may vary. Confirm RoHS compliance status through official documentation prior to integration. Ensure the selected variant matches the required impedance and current ratings for the target application circuit design.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0201 footprint with moderate noise suppression needs. Evaluate the 0.15 A current rating against peak load requirements to prevent saturation. Consider the 220 Ohm impedance profile for the specific frequency band of interference to be attenuated in the power or signal lines.

Chip Ferrite Bead Part Context

This part belongs to the BK series H type, designed for high-current applications in small form factors. It serves as a ferrite bead inductor, distinct from general-purpose inductors like the LHL series or RF inductors like the HKQ series. The series targets automotive and industrial electronics requiring robust EMI performance.
