Description

General part information

R-78B Series

The R-78B3.3-1.5 is a 1-output 4.95W through hole-mount non-isolated DC/DC Converter with 95% efficiency. High efficiency switching regulator is ideally suited to replace 78xx linear regulators and are pin compatible. The efficiency of up to 95% means that very little energy is wasted as heat so there is no need for any heat sinks with their additional space. The L-Version with 90° pins allows direct replacement for laid-flat regulators where component height is at a premium. Low ripple and noise figures and a short circuit input current of typically only 10mA round off the specifications of this versatile converter series.
