BK1005LL330-T

Overview

The BK1005LL330-T is a multilayer chip bead inductor from the Taiyo Yuden BK series, designed for surface-mount applications. It features a 0402 (1005 metric) package with dimensions of 1.00mm length, 0.50mm width, and a maximum height of 0.55mm. The component provides an impedance of 33 Ohms at 100 MHz and supports a maximum DC current of 400mA. Its maximum DC resistance is 250 milliohms. It operates within a temperature range of -55°C to 125°C and complies with RoHS3 standards.

Feature Summary

• Multilayer construction for compact high-frequency noise suppression
• Low DC resistance design for minimal power loss
• Surface-mount compatibility for automated assembly

Applications

• High-speed data line filtering
• Power supply noise attenuation
• EMI suppression in portable electronics

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS3 compliance and MSL rating during sourcing. Check for valid replacement parts like MPZ1005F330ETD25 if availability is critical. Ensure storage conditions meet moisture sensitivity requirements before reflow soldering.

Selection Notes

Select this component for circuits requiring 33 Ohm impedance at 100 MHz in a 0402 footprint. Ensure the 400mA current rating meets load requirements. Consider thermal performance within the -55°C to 125°C range. Verify PCB land pattern matches 1.00mm x 0.50mm dimensions for proper placement.

Part Context

This ferrite bead belongs to Taiyo Yuden's BK series, specialized for multilayer chip bead inductors. It targets EMI/RFI suppression in digital and analog circuits. The 0402 size offers space efficiency for dense PCB layouts. It serves as a passive filter element in signal integrity management.

Replacement Considerations

MPZ1005F330ETD25 by TDK is listed as a direct substitute. Verify electrical parameters and package compatibility before substitution.
