RECOM Switching Regulator, Right-Angled Pins, 91% Maximum Efficiency - R-78B-1.5 Series - R-78B3.3-1.5L


Pin down voltage conversion in compact setups with this switching regulator from RECOM. Thanks to right-angled contacts, it lies flat while connected, helping you settle supply issues without using much space. By reaching up to 91% efficiency, the unit keeps a cool head during conversion so there's no need to hook up a heatsink. An input voltage range between 4.75 and 18V DC makes the regulator a sure fit for standard power supplies. It comes with integrated short-circuit protection, so you can trust it's more than a match for electrical faults.

• Epoxy resin potting and plastic case provide effective insulation to protect against electrical hazards
• Through-hole mounting for quick installation
• Power dissipation of just 0.65W to minimise energy loss
• Maximum line regulation rating of ±0.5%, ensuring a stable output voltage for a reliable power supply

Applications


• Remote-control devices
• Electric vehicle chargers
• Construction industry

Do I need to use shielded cables with this switching regulator?


No, this unit generates low ripple voltages up to 30mV, so there's no need to use shielded cables to protect against electrical noise.
