TKA-W25 Series
DESCRIPTION 0.25W 3KVDC Isolated Miniature Single Output DC/DC Converters
The TKA-W25series are miniature, isolated 0.25W DC/DC converters in a SIP and DIP package. They offer the ideal solution in many space critical applications for board level power distribution. The Internal SMD construction makes it possible to offer a product with high performance at low cost. The series offers smaller size, improved efficiency, lower output ripple noise and 3KVDC isolation.
FEATURES
RoHS compliantCE certification UL 94V-0 package material Power sharing on output Efficiency up to 83% Internal SMD construction Input voltage :3.3V, 5V ,12V ,24V Operating temperature: -40 to 105 Industry standard pinout Output voltage: 3.3V, 5V, 9V,12V,15V,24V
