Power Inductor & 2 in 1 Power Transformer < SMD Type: CLS Series>
Type: CLS127
◆
Product 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: 4.8g(Ref.).
Ideally used in the power supply for DSC Note PC DVC and W-LED backlighting.
