RECOM DC-DC Converter, 3kV Isolation, Single Output Type - RK Series - RK-0505S

To adjust the voltage level from your DC power source, choose this 1W DC-DC converter from RECOM. It turns an input between 4.5 and 5.5V DC into a stable 5V DC output with a 200mA current for the easy powering of a compatible circuit. By supplying the correct voltages to your parts, you can prevent breakdowns and damage for a smoother, more efficient process. The device's maximum operating humidity of 95% RH lets it thrive in steamy setups. And with its light weight of 2.6g, it doesn’t put pressure on your system.

Features & Benefits

• High efficiency rating of 70 to 78%, so it's an energy-saving component

• Broad operating temperature range of -40°C to +90°C for use in harsh work areas

• MTBF of just under one million hours shows it's highly reliable

• Through-hole mounting design for installing securely on your printed circuit board

• Integrated isolation blocks noise and interference to ensure greater signalling efficiency

Applications

• Automotive industry

• Medical devices

• Smart lighting

• Energy drives

How big is this product?

This converter has a slim size of 19.65 (L) x 6.0 (W) x 10.2mm (H), so it doesn’t take up a lot of space on your board.
