Power adapter/inverter MEAN WELL SPB09A-05, output 5 V, 9 W, RoHS compliant, 24 mm depth, 5 g

MEAN WELL SPB09A-05 is a compact DC-DC regulated converter in a SIP through-hole package, providing a single 5 V output at up to 1.6 A (9 W) from a wide 9–18 V DC input. The module includes a remote ON/OFF control and is RoHS compliant. With a depth of 24 mm and a weight of 5 g, it is intended for PCB-mount applications where space and weight are limited.

Advantages

The SPB09A-05 offers regulated 5 V output with up to 1.6 A current capability in a small SIP footprint suitable for PCB through-hole mounting. Its wide input range (9–18 V) and remote ON/OFF feature provide flexible integration options. The converter is RoHS compliant and designed for compact installations and mass-production assembly, supported by a small physical depth (24 mm) and low weight (5 g).

How to use

Mount the SPB09A-05 in a compatible SIP through-hole footprint on the PCB and solder according to standard through-hole assembly practices. Apply an input voltage within the specified 9–18 V DC range and connect the load to the 5 V output, ensuring the load does not exceed 1.6 A. Use the remote ON/OFF control to enable or disable the output as required. Follow recommended PCB layout guidelines for power modules (short input/output traces, adequate grounding and decoupling) to ensure stable operation.

Recommendations

Use appropriate decoupling capacitors near the input and output, observe thermal limits for continuous 1.6 A output, and ensure the input supply can provide sufficient current. For reliable long-term operation, maintain ambient temperature and ventilation within the module's specified limits and consult the manufacturer's datasheet for detailed electrical and mechanical specifications.
