SK01S/D Sries 1W DC/DC CONVERTER, SMD-Package FEATURES Ultra compact SMD Packagef Wide 2:1 lnput Range Fully regulated Outputs Low Ripple and Noise Operating Temp. Range -40°C to +85°C I/O-isolation Voltage 1500VDC Continuous Short-circuit Protection Remote On/Off Control Qualified for Lead-free Reflow Process UL/cUL/IEC/EN 60950-1 Safety Approval (pending) 3 Years Product Warranty The SK01S/D series is a family of compact 1W dc/dc-converters with wide 2:1 input voltage ranges and tightly regulated output voltages. They work with high efficiency over the full load range and come with a remote On/Off control input. High efficiency to 82% allows operating temperatures up to +75°C without power derating. The very small footprint of these converters make them an ideal solution for many space critical applications in communication equipment, instrumentation and many other battery operated applications.

We recommend to protect the converter by a slow blow fuse in the input supply line. Other input and output voltage may be available, please contact factory. That “natural convection” is about 20LFM but is not equal to still air (0 LFM). Specifications are subject to change without notice.
