Sumida CLS4D28B-5R2NB Power inductor & 2 in 1 transformer Datasheet

Power Inductor & 2 in 1 Transformer < SMD Type: CLS Series>
Under Development
Type: CLS4D28B
◆ 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
・Max. Operating frequency: 1MHz.
・2 in 1 Coils for high efficiency up-down DC-DC converters.(SEPIC, Zeta, Cuk converter).
・Storage temperature range: -40℃~+105℃.
・Operating temperature range: -40℃~+105℃ (including coil’s self-heat).
・Product weight: 230mg(Ref.).
・Ideally used in the power supply for DSC、Note PC、DVC and W-LED backlighting.
