Overview
The BK0402HM151-T is a multilayer chip ferrite bead from the BK series, manufactured by Taiyo Yuden. It functions as a signal line filter with one circuit path. The component exhibits an impedance of 150 Ohms at 100 MHz and supports a maximum current rating of 200mA. Its DC resistance (DCR) is specified at a maximum of 650 milliohms. The device utilizes a 01005 (0402 metric) surface-mount package, measuring 0.40mm in length and 0.20mm in width, with a maximum height of 0.22mm. It operates within a temperature range of -55°C to 125°C.
Feature Summary
- Multilayer construction for compact signal line filtering
- High impedance characteristics at 100 MHz
- Low DC resistance for minimal signal loss
- Surface-mount design for automated assembly
Applications
- General electronics equipment
- Telecommunications devices
- Mobile phones and PCs
Procurement Notes
This component is officially listed as obsolete and no longer manufactured by Taiyo Yuden. Verification of availability should focus on alternative sources or direct substitutes rather than new production units. Confirm RoHS3 compliance status through official documentation if required for specific regulatory environments. Validate that any replacement part matches the electrical specifications and physical footprint exactly.
Selection Notes
Select this component only if the 01005 footprint and 150 Ohm impedance at 100 MHz align with the circuit requirements. Ensure the 200mA current rating suffices for the application's peak load. Due to its obsolete status, prioritize verified direct replacements like the Murata BLM02BX151SN1D to maintain supply chain stability and performance consistency.
Part Context
Part of the BK series multilayer chip beads designed for high-density PCB layouts. The 01005 package size allows for miniaturization in portable consumer electronics. It serves as a passive EMI suppression element, attenuating high-frequency noise on single signal lines without significantly affecting the desired signal bandwidth.
Replacement Considerations
The Murata BLM02BX151SN1D is documented as a direct substitute. Verify that the replacement maintains identical impedance curves and current ratings to ensure circuit compatibility.
FAQ
