BK2125HM121-TV

Overview

The BK2125HM121-TV is a multilayer chip bead inductor manufactured by Taiyo Yuden, designed for automotive applications. It features an output impedance of 120 Ohms with a tolerance of 25%. The component has a maximum DC resistance of 0.15 Ω and a rated current of 0.8 A. It operates within a temperature range of -55 °C to +125 °C. The physical dimensions are 2.0 mm in length, 1.25 mm in width, and 0.85 mm in height, corresponding to the 0805 (2012 metric) package size. It is qualified under the AEC-Q200 standard.

Feature Summary

AEC-Q200 qualified for automotive reliability
Multilayer ceramic construction for high-frequency noise suppression
Surface mount design for automated assembly

Applications

Automotive electronic circuits
Industrial equipment signal lines
Medical equipment power filtering

Procurement Notes

Verify the specific suffix 'TV' against official Taiyo Yuden documentation to confirm packaging details. Ensure the part number matches the exact impedance and current ratings required for the target circuit design. Cross-reference the AEC-Q200 qualification status if automotive compliance is mandatory for the final product.

Selection Notes

Select this component when a 120 Ohm impedance at the specified frequency is required for EMI suppression in space-constrained designs. The 0.8 A rated current must be sufficient for the application's operating conditions. Consider the -55 °C to +125 °C operating range to ensure stability in harsh environments typical of automotive or industrial settings.
