Recom R1SX 1W SMD Isolated DC-DC Converter


The R1SX is a low cost, 1 W, low profile, open-frame, SMD isolated DC-DC converter. It is available with 3.3 V or 5 V inputs and offers a single unregulated 3.3 V or 5 V output. There is no minimum load requirement and the quiescent consumption is less than 150 mW. Isolation is 1 k V dc or 3 k V dc and the operating temperature is -40°C up to +100°C (without derating). The pin-out is industry standard and compatible with the R1S series, but at half the height. The converter is fully certified to IEC/EN/UL62368 and 60950 and is 10/10 RoHS-conform. Class B EMC conformity can be reached with a simple external LC filter.

Features and Benefits


• 1 W Power in SMD Package
• Low cost
• Pin Compatible with R1S Series
• -40°C to +100°C Operating Temperature @ Full Load

• IEC/EN/UL62368-1 Certified, CB Report
• High 3 k V dc/1 second or 1 k V dc/1 second isolation

RECOM DC-DC Converter, 74% Efficiency, Surface Mounting - R1SX Series - R1SX-3.33.3-R


Take charge of the power supply to your PCB-connected parts with this DC-DC converter from RECOM. It cleans out interference, ripple and noise from the input voltage signal. That means you're left with a balanced 3.3V output that's safe for low-voltage components like LED lamps and sensors. Thanks to its durable plastic housing, this unit handles impact without breaking a sweat, making it useful in harsh environments. The material also serves as reliable insulation to prevent you from getting any shocking surprises during installation and operation.

• Efficiency of 74% for improved productivity and minimal energy wastage
• Isolation voltage of 1kV protects connected parts from sudden power surges
• Broad operating temperature range between -40°C to +100°C for use in challenging settings
• Mean time between failures of 21,400,000 hours at +25°C for long-term performance

Applications


• Automotive industry
• Machine building
• Medical equipment

What size is this DC-DC converter?


This unit has compact dimensions of 12.75 (L) x 11.1 (W) x 5.8mm (H), making it a space-efficient choice for busy setups.

Is this converter flame-resistant?


Yes, it stops burning in 10 seconds or less in the event of a fire, so it's a safe choice for volatile work areas.
