CUI Inc P78-500/P78-500R Non-Isolated Switching Regulators

CUI Inc P78-500 / P78-500R Non-Isolated Switching Regulators feature 0.5A output current, up to 10:1 input range (9VDC to 90VDC), and no-load input current as low as 1.5mA. These regulators are offered with the option of a straight pin (no suffix) or bent pin (R suffix). The straight pin module comes in a 17.5mm x 11.5mm x 9mm package, while the bent pin variant has a 19mm x 11.5mm x 9mm size. CUI Inc P78-500 / P78-500R Non-Isolated Switching Regulators deliver 2M hours mean time between failures (MTBF). The devices use natural convection cooling and have a -40°C to +85°C temperature range. P78-500 / P78-500R regulators are RoHS compliant and certified to EN/IEC 62368 requirements.
