BKP1005EM221-TV

Chip Ferrite Bead Overview

The Taiyo Yuden BKP1005EM221-TV is a multilayer ferrite chip bead designed for high-current applications. It features an impedance of 220 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 800 mA and exhibits a low maximum DC resistance of 200 mOhms. Housed in a compact 0402 (1005 metric) surface-mount package, it operates within a temperature range of -55°C to +85°C.

Chip Ferrite Bead Feature Summary

• Engineered for high-current suppression in compact form factors
• Provides effective noise attenuation at 100 MHz
• Features low DC resistance to minimize power loss

Chip Ferrite Bead Applications

• High-current signal line filtering
• Power supply noise suppression
• EMI reduction in automotive electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'TV' against official manufacturer documentation to confirm packaging and tape specifications. Confirm availability status as distribution channels may list this part as discontinued or limited stock. Ensure the selected variant matches the required current rating and impedance tolerance for the target circuit design.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0402 footprint but high current handling is necessary. Compare the 800 mA rating against circuit load requirements. Consider the 200 mOhms DC resistance impact on voltage drop. Verify thermal performance within the specified operating temperature range during integration.

Chip Ferrite Bead Part Context

This part belongs to the BKP series of multilayer ferrite beads from Taiyo Yuden. It shares the 0402 package dimensions with other variants like BKP1005HS221-TV but differs in electrical characteristics such as current rating and temperature range. The series is designed for general-purpose EMI suppression in portable and industrial devices.
