RECOM Switching Regulator, 2.5W Power Rating, 81% Efficiency - R-78HB Series - R-78HB5.0-0.5
This switching regulator from RECOM is a safe power distribution solution for your electronic circuits. It monitors the input voltage and converts it to a stable output supply components on the circuit can use. Thanks to a wide input tolerance range of 9 to 72V, this versatile unit can be used with various power sources. Its non-conductive plastic housing serves as an insulator to protect you from electric shocks. Continuous short-circuit protection and thermal shutdown features ensure this device is powered down in the event of a fault, preventing damage to the circuit.
Features & Benefits
• Compact dimensions of 11.5 (length) x 8.5 (width) x 17.5mm (height) for installation in setups with limited space
• Through-hole mounting style provides a permanent, vibration-proof connection
• Flame retardant, as burning stops in 10 seconds when a fire occurs
• Integrated 1μF capacitor serves as a filter to smooth out the voltage for noiseless signal transmission
