744916087

Fixed Inductors Overview

The Würth Elektronik 744916087 is a surface-mount fixed inductor from the WE-KI HC series, designed for high-current applications. It features an 8.7 nH nominal inductance with a ±2% tolerance and utilizes a ceramic drum core wirewound construction. The component operates without shielding and has a maximum DC resistance of 65 mΩ. It supports a rated current of 1.5 A and achieves a self-resonant frequency of 5 GHz. The unit is housed in a compact 0402 (1005 metric) package, measuring 1.00 mm in length, 0.50 mm in width, and 0.50 mm in height. It is qualified to AEC-Q200 standards and functions within a temperature range of -40°C to +125°C.

Fixed Inductors Procurement Notes

Verify the specific ordering suffix matches the required packaging format, such as tape and reel or cut tape, as these affect handling procedures. Confirm that the RoHS3 compliance status aligns with environmental regulations applicable to the target market. Ensure the supplier provides valid traceability documentation for the AEC-Q200 certification if the application requires strict automotive quality assurance protocols.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 8.7 nH is required alongside significant current capacity. The 0402 package size is appropriate for space-constrained designs where standard inductors are too large. Consider the 5 GHz self-resonant frequency to ensure effective performance at higher frequencies compared to larger packages. Evaluate the 65 mΩ DCR against voltage drop requirements in the specific circuit topology.

Fixed Inductors Part Context

This part belongs to the WE-KI HC series, which specializes in SMD high-current wirewound ceramic inductors. The series is engineered to provide robust performance in demanding environments while maintaining small physical dimensions. The 744916087 variant specifically targets applications requiring minimal inductance values with high saturation characteristics, distinguishing it from lower-current variants in the broader product line.
