1.0 AMP SMD Single Output DC/DC-Converter Data Sheet

RECOM DC-DC Converter, Open Frame Package, ±0.4% Load Regulation - R78T Series - R-78T5.0-1.0/FC-TRAY

Seeking stable voltages to safely power your sensitive PCB-mounted equipment? The search is over now you've found this SMD-type DC-DC converter from RECOM. It steps down inputs across a broad range of 8 to 42V DC to deliver a carefully regulated output of 5V DC. The unit's tight line and load regulation of ±0.2% and load ±0.4% respectively means you can put money on predictable results. Thanks to the low noise values of typically 50mVp-p, max 100mVp-p, there's little risk of electrical spikes damaging connected devices.

Features & Benefits

• Open frame package helps keep device cool

• Compact dimensions of 23(L) x 29.4 (W) x 8mm (H) make it easy to fit onto your PCB

• Standard FC tray pinout configuration, so it's a piece of cake to solder in place

• Mean time between failures of 367,000 hours for a long service life

• ±2% typical accuracy for reliability

Applications

• Telecommunications hubs

• Consumer electronics

• Medical devices

What's this unit's efficiency rating?

This converter offers an efficiency between 85 and 92%, so you can Trust it generates very little heat. This means you'll have no need for a heatsink and can safely rely on its free-air convection alone.

R-78Txx 1.0 Series Single Output DC/DC Converter

The Recom R-78T series of DC-DC converters are compact, low profile SMD switching regulators. They have 3 standard pinning options: AC, AL and FC.

The R-78T series has a high efficiency of up to 95%, which means that these DC-DC converters do not require heatsinks or fans. The switching regulator can operate reliably between -40°C and 85°C without derating. These DC-DC converters are the Ideal space-saving solution for portable battery-operated applications.
