Fonte de alimentação MEAN WELL DKM10A-12 10W 12V 0,42A RoHS

The MEAN WELL DKM10A-12 is a compact DC-DC converter designed for PCB mounting. It accepts an input voltage range of 9–18 VDC and provides dual outputs of ±12 V with up to ±0.42 A on each rail. The module is supplied in a DIP through-hole package with an ultra-compact 1" x 1" footprint and is RoHS compliant, weighing approximately 18 g.

Advantages

This DC-DC converter delivers isolated dual outputs in a very small form factor suitable for space-constrained PCBs. The through-hole DIP package simplifies soldering and mechanical retention on standard boards. Low weight and RoHS compliance make it appropriate for commercial and industrial designs where lead-free components are required. The wide input range (9–18 VDC) offers flexibility for use with various 12 V vehicle or battery-powered systems.

Suitable for

• Embedded systems and control boards requiring ±12 V rails
• Industrial and commercial electronics with limited PCB space
• Backup or battery-powered equipment with 9–18 V supplies

How to use

Mount the DKM10A-12 onto the PCB using standard through-hole soldering practices, observing correct polarity for input and output pins. Provide appropriate input filtering and follow the manufacturer’s recommended grounding and layout to ensure stable operation. Verify that the available input source falls within the 9–18 VDC range and that the load on each output does not exceed ±0.42 A to prevent overheating or shutdown.

Recommendations

For reliable performance, allow adequate ventilation around the module and avoid operating at maximum load continuously. Use decoupling capacitors on sensitive circuits and follow MEAN WELL datasheet guidance for thermal management and mounting clearances.
