BK1608HW121-T

Overview

The BK1608HW121-T is a multilayer chip ferrite bead from the BK series by Taiyo Yuden, designed for noise suppression in electronic circuits. 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 and supports a maximum rated current of 600mA. Its DC resistance (DCR) is maximized at 150 milliohms. It operates within a temperature range of -55°C to 125°C and holds AEC-Q200 qualification.

Feature Summary

• Multilayer construction for effective high-frequency noise attenuation
• AEC-Q200 qualified for automotive reliability standards
• Compact 0603 footprint suitable for space-constrained designs

Applications

Procurement Notes

Verify current availability status as this part may be discontinued or subject to production changes. Confirm RoHS3 compliance and REACH status during sourcing. Check for official Product Change Notifications (PCN) regarding manufacturing updates. Ensure substitute components meet identical electrical specifications if original stock is unavailable.

Selection Notes

Select this component when a 120 Ohm impedance at 100 MHz is required for single-line power filtering. The 600mA current rating suits low-to-medium power applications. The AEC-Q200 qualification makes it appropriate for automotive environments. Compare DCR and impedance characteristics against alternative ferrite beads to ensure compatibility with target circuit noise profiles.

Part Context

This component belongs to Taiyo Yuden's BK series of multilayer chip bead inductors. These parts are engineered for electromagnetic interference (EMI) suppression in compact electronic assemblies. The series offers various impedance and current ratings across standard package sizes to support diverse filtering requirements in modern hardware designs.
