BK1608LL181-TV

Overview

The BK1608LL181-TV is a multilayer ferrite bead inductor manufactured by Taiyo Yuden. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.95 mm height. The component provides an impedance of 180 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 250 mA and has a maximum DC resistance of 650 mOhms. The device operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• Multilayer chip construction for compact surface-mount integration
• AEC-Q200 qualified for automotive reliability standards
• High-impedance noise suppression at 100 MHz
• Wide operating temperature range suitable for harsh environments

Applications

• Automotive electronic circuit noise filtering
• EMC suppression in high-frequency signal lines
• Power supply line filtering for sensitive components

Procurement Notes

Verify the specific suffix TV against official Taiyo Yuden documentation to confirm packaging and handling specifications. Confirm end-of-life status via Product Change Notification records before design finalization. Ensure compatibility with existing footprint designs as this is a discontinued series. Cross-reference impedance values at 100 MHz to validate performance requirements.

Selection Notes

Select this component when automotive-grade reliability is required for noise suppression in space-constrained designs. The 0603 package allows for dense PCB layouts while maintaining adequate current handling for low-power circuits. Verify that the 180 Ohm impedance profile matches the target noise spectrum. Consider alternative active series if new production volume is needed due to discontinuation.

Part Context

This part belongs to the BK series of multilayer ferrite beads from Taiyo Yuden. These components are designed for electromagnetic interference suppression in digital and analog circuits. The LL designation typically indicates a specific material composition optimized for high-frequency attenuation. The series is widely used in consumer electronics and automotive applications requiring reliable noise control.
