RECOMSwitching Regulator, Through Hole, 3 Terminal Pins - R-78HB Series - R-78HB3.3-0.5
Safeguard your appliances with this switching regulator from RECOM. It's a DC-DC power converter that steps down a high varying voltage to a fixed voltage, making it ideal for use in systems that could suffer damage from fluctuating power. The unit comes with a three-pin terminal for easy installation onto your PCB. As it comes with integrated short-circuit protection, it acts as a buffer to safeguard attached devices in the event of a power surge. Thanks to a wide operating temperature range between -40°C and +85°C, this regulator performs safely in harsh conditions.
