BK1608HS121-T

Overview

The BK1608HS121-T is a single-line multilayer chip ferrite bead manufactured by Taiyo Yuden, designed for electromagnetic interference suppression in power lines. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.60mm x 0.80mm and a maximum height of 0.95mm. The component provides an impedance of 120 Ohms at 100 MHz while supporting a maximum rated current of 400mA to 500mA depending on specific datasheet revisions. Its direct current resistance (DCR) is specified at a maximum of 180 milliohms to 850 milliohms. It operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Multilayer ceramic construction for high reliability and low failure rates
• Designed for effective electromagnetic interference suppression on power lines
• Compact 0603 surface-mount footprint suitable for dense PCB layouts

Applications

• Electromagnetic interference filtering in portable electronic devices

Procurement Notes

Verify the exact electrical parameters against the latest official datasheet before integration, as specifications such as DCR and current rating may vary between production batches or datasheet revisions. Confirm that the 0603 package dimensions and thermal characteristics align with your board design constraints. Ensure compliance with project-specific environmental regulations beyond standard RoHS3 requirements if applicable.

Selection Notes

Select this component when a compact ferrite bead is required for power line filtering with moderate current handling capabilities. The 0603 package offers a balance between size and performance compared to smaller 0201 options. Consider the specific impedance curve at 100 MHz and the DC resistance limits to ensure minimal voltage drop and adequate noise attenuation for the target application frequency spectrum.
