Τροφοδοτικό/μετατροπέας MEAN WELL SPBW03F-03, έξοδος 3 W, 0,7 A

MEAN WELL SPBW03F-03 is a compact DC‑DC converter designed for PCB mounting and through‑hole SIP installation. With a regulated single output of 3.3 VDC at up to 0.7 A and an input range of 9–36 VDC, this 3 W power module is intended for low‑power electronics and LED modules that require stable voltage conversion on printed circuit boards. The converter meets RoHS requirements and is supplied in bulk packaging for volume assembly.

Advantages

The module offers a wide input voltage range and a stable 3.3 V output at 0.7 A in a small SIP through‑hole package suitable for direct PCB mounting. Its compact size and regulated output simplify power design for low‑power devices, while RoHS compliance supports environmentally conscious manufacturing. The device's single output and straightforward pinout reduce design complexity for embedded systems.

Suitable for

• Low‑power embedded electronics and microcontroller boards
• LED modules and lighting control circuits
• Battery‑powered systems requiring step‑down conversion
• Industrial and instrumentation PCBs with limited space

Key specifications

• Type: DC‑DC converter, PCB mount, SIP through‑hole package
• Input voltage range: 9–36 VDC
• Output: single regulated 3.3 VDC
• Maximum output current: 0.7 A
• Output power: 3 W
• Mounting: through‑hole SIP for direct PCB insertion
• Standards: RoHS compliant

How to use

Install the converter into the PCB using the SIP through‑hole pins and solder according to standard through‑hole soldering practices. Apply an input voltage within the specified 9–36 VDC range and verify correct polarity before power‑up. Connect the 3.3 V output to the target circuit, ensuring the load does not exceed 0.7 A. Provide adequate PCB copper area or heatsinking if continuous operation near maximum load is expected, and include input/output decoupling components as recommended by the system designer to minimize noise.

Recommendations

Use within the specified input range and avoid sustained operation at maximum current without adequate thermal management. Place the module clear of high‑temperature components and plan PCB layout to allow airflow. Add filtering and transient protection on the input if the converter is used in electrically noisy environments.
