Overview
The BK1005LL100-T is a multilayer chip bead inductor from the Taiyo Yuden BK series, designed for EMI suppression. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.00mm x 0.50mm and a maximum height of 0.55mm. The component provides an impedance of 10 ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 110 milliohms. The device operates within a temperature range of -55°C to +125°C and is classified as unshielded.
Feature Summary
- Multilayer construction for compact surface-mount integration
- Designed for electromagnetic interference suppression in electronic circuits
- Unshielded ferrite chip bead configuration
Applications
- EMI suppression for general electronic circuits
- Signal line filtering in portable devices
- Power supply noise reduction
Procurement Notes
This component is officially listed as obsolete and no longer manufactured by Taiyo Yuden. Verification of availability should focus on identifying qualified substitute parts or checking remaining stock from authorized distributors. Direct procurement from the manufacturer is not possible due to end-of-life status. Engineers must validate alternative components against original electrical specifications before implementation.
Selection Notes
Selection requires evaluating equivalent ferrite beads with matching 10-ohm impedance at 100 MHz and 500 mA current rating. The 0402 footprint constraint necessitates verifying physical dimensions of substitutes. Considerations include maintaining similar DC resistance values to minimize voltage drop and ensuring thermal stability within the specified operating temperature range for the target application environment.
Part Context
The BK1005LL100-T belongs to the BK series of multilayer chip bead inductors produced by Taiyo Yuden. This series utilizes proprietary multilayer technology to achieve high performance in small packages. The component serves as a passive filter element, converting high-frequency noise energy into heat to protect sensitive circuitry from electromagnetic interference.
Replacement Considerations
Publicly confirmed substitutes include BLM15AG100SH1D by Murata Electronics and BBSY00100505181Y00 by Pulse Electronics. These alternatives offer parameter-equivalent or direct replacement options for the discontinued part.
