TDK BCL3520FT-D Inductors

TDK BCL3520FT-D Inductors are designed for automotive power circuits and feature a small footprint with dimensions of 3.3mm x 3.5mm x 2mm. These power inductors offer a typical DC resistance range of 2.7mΩ to 10mΩ, a typical rated current range of 6.6A to 15.9A, and a rated voltage of 40V. The BCL3520FT-D modules use a flat wire instead of a standard round wire, reducing heat generation and power loss. These high-reliability inductors can be used in high-temperature environments up to +155°C. The BCL3520FT-D inductors from TDK are AEC-Q200 compliant.
