Fonte de alimentação/transformador MEAN WELL SPBW03F-05 — 3 W, 5 V, 0,6 A

MEAN WELL SPBW03F-05 is a compact DC-DC converter designed for PCB mounting that delivers a regulated 5 V output at up to 0.6 A from a wide 9–36 V DC input range. Housed in a SIP through-hole package, this 3 W power adapter/inverter provides a stable low-voltage supply for low-power electronics and embedded systems while meeting RoHS environmental standards.

Advantages

The converter’s small footprint and SIP through-hole form factor simplify integration into printed circuit boards and constrained enclosures. Wide input range allows operation from diverse power sources, and the regulated 5 V output maintains stable voltage for sensitive sensors and small controllers. Low power dissipation and 3 W rating make the unit suitable for auxiliary modules and battery-backed systems where efficiency and minimal thermal load are important.

Suitable for

• Powering sensors and sensor nodes in embedded applications
• Supplying small microcontroller boards and logic modules
• Auxiliary power for communication or monitoring modules
• Industrial or automotive systems operating from 9–36 V DC rails
• PCB-mounted designs requiring a compact SIP through-hole regulator

Key specifications

• Output voltage: 5 V DC
• Maximum output current: 0.6 A
• Output power: 3 W
• Input voltage range: 9–36 V DC
• Conversion type: DC-DC isolated converter for PCB mount
• Package: SIP through-hole
• Compliance: RoHS

How to use

Install the SIP through-hole converter onto the PCB in the designated footprint, ensuring correct orientation and secure solder joints. Connect the input terminals to a DC source within the 9–36 V range and route the regulated 5 V output to the target circuitry, observing correct polarity. Allow adequate clearance for heat dissipation and follow standard PCB grounding and decoupling practices to minimize noise. Verify output voltage under expected load conditions before final deployment.

Recommendations

For reliable operation, avoid exposing the converter to input voltages outside the specified 9–36 V range and ensure the output load does not exceed 0.6 A. Provide sufficient copper area or thermal vias near the package for heat spreading in continuous-load applications. Use input and output decoupling capacitors close to the pins to improve transient response and reduce noise in sensitive circuits.
