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.

Features & Benefits

• 3.3V DC output voltage makes it suitable for use in low-power applications

• 800kHz maximum switching frequency at full load for fast and efficient control

• 0.5A maximum current for low heat dissipation

• 4g weight for minimal strain on your PCB

Applications

• Telecommunications systems

• Domestic appliances

• Automotive industry

• Communication and networking devices

What size is this component?
