Power Adapter MEAN WELL DLC03A-05 3W 5V 0.3A RoHS

The MEAN WELL DLC03A-05 is a compact DC-DC converter module in a DIP through‑hole package designed for PCB mounting. It accepts an input voltage range of 9–18 Vdc and provides a dual output of ±5 Vdc with a maximum output current of ±0.3 A per rail. The module delivers 3 W total output power and is RoHS compliant.

Advantages

This DLC03A-05 converter is compact and suitable for space-constrained PCB designs, offering bipolar outputs for circuits that require both positive and negative supply rails. Its through‑hole DIP construction simplifies assembly for prototyping and production environments that use standard soldering techniques. Compliance with RoHS ensures reduced levels of hazardous substances.

Suitable for

• Small industrial and embedded electronic systems requiring ±5 V rails
• Analog signal circuitry and operational amplifier power supplies
• PCB-mounted prototypes and through‑hole assembly workflows

How to use

Mount the DLC03A-05 into the designated DIP through‑hole footprint on the PCB and solder according to standard soldering practices for through‑hole components. Apply a DC input in the specified 9–18 Vdc range to the input pins, and observe polarity to avoid damage. Use the ±5 Vdc output rails to power the target circuit, ensuring the combined load does not exceed the module's rated current and total power.

Recommendations

Ensure adequate PCB layout practices for thermal dissipation and maintain clearance between the module and heat‑sensitive components. If noise-sensitive analog circuitry is used, add recommended decoupling capacitors on the output rails and follow grounding best practices. Verify the input supply can provide sufficient current within the 9–18 Vdc range before connecting sensitive loads.
