ETQ-P1W Metal Composite Power Choke Coils

Panasonic's ETQ-P1W is a low-profile power choke coils offering high current capacity and low loss

Image of Panasonic's ETQ-P1W Metal Composite Power Choke Coils The ETQ-P1W Series is suitable for high switching frequencies up to 1 MHz and features a metal composite construction. This results in a smaller size (5.4 x 5.15 mm) and a low profile (only 1.2 mm), while providing high current capability (2.2 to 5.5 A) and low loss (RDC 19.2 to 168.0 mOhm) in addition, a distributed gap structure yields little audible noise during usage.
