Datasheet

COO (Country of Origin):: TW

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

Applications

• Automotive industries

• Instrumentation equipment

Do I need a heat sink for this regulator?

No, because this regulator has an efficiency of 81%, meaning it makes optimal use of energy and it doesn't dissipate much heat.
