Power Inductor & 2 in 1 Transformer < SMD Type: CLS Series>
Type: CLS4D18
◆
Description
・4
Terminal pins’ type gives a flexible design as inductors or transformers.
・Can
also be used as a coupled inductor, two single inductors connected
in parallel, as 1:1 transformer or as an autotransformer when connected
in series.
・Core
material: Ferrite.
・Custom
design is available.
◆
Feature
