BK0402HM331-T

Overview

The BK0402HM331-T is a multi-layer ferrite bead chip manufactured by Taiyo Yuden, designed for high-frequency noise suppression in compact electronic circuits. This component features a single signal line configuration housed in a 01005 (0402 metric) surface-mount package with dimensions of 0.40mm length and 0.20mm width. It exhibits an impedance of 330 Ohms at 100 MHz and maintains a maximum DC resistance of 1.2 Ohms. The device supports a rated current of 150mA and operates within a temperature range of -55°C to 125°C.

Feature Summary

Multi-layer construction enables effective high-frequency noise attenuation in miniature form factors
Single-line signal filtering capability optimizes space-constrained circuit layouts
Robust thermal stability ensures reliable performance across extended industrial temperature ranges

Applications

High-frequency noise countermeasures in personal computers
Signal integrity management in digital cameras
EMI suppression in information system products

Procurement Notes

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm RoHS3 compliance and moisture sensitivity level 1 status during sourcing. Check for product change notices or obsolescence alerts prior to final design approval. Ensure packaging specifications match automated assembly requirements.

Selection Notes

Select this component when ultra-compact footprint is critical alongside specific 330 Ohm impedance requirements at 100 MHz. Evaluate the 150mA current rating against circuit load demands to prevent saturation. Consider the 0.65 Ohm DCR impact on signal loss for sensitive analog paths. Compare physical dimensions against board space limitations before integration.

Part Context

This ferrite bead belongs to Taiyo Yuden's BK series, specialized for EMI suppression in portable and digital devices. The 01005 package represents one of the smallest standard footprints available for such components. It complements other passive filters in complex signal conditioning networks requiring precise frequency-dependent attenuation characteristics.
