FAQ

Can I use the SPAN02E-03 for a 3.3V microcontroller board inside industrial controls?

It can fit low-power 3.3V control electronics because it provides a constant 3.3V output at 2W. The 21.8 × 11.1 × 9.2 mm package also suits compact embedded assemblies where board space is limited.

Is the SPAN02E-03 suitable for 3.3V sensor or interface circuits in automation equipment?

It is aimed at low-power 3.3V loads, so it can be a fit for embedded sensor and interface sections that need constant voltage rather than a higher-power rail. The 2W rating makes it more appropriate for control electronics than for larger field devices.

Can this converter be used in compact IT or communications hardware that needs 3.3V?

Yes, it is sized for compact low-power 3.3V electronics, with constant-voltage output and a 21.8 × 11.1 × 9.2 mm body. That profile is better aligned with embedded logic and support circuits than with higher-power 3.3V loads.

Is the SPAN02E-03 a good fit for space-constrained embedded designs?

The small 21.8 × 11.1 × 9.2 mm dimensions and 0.0048 kg weight make it practical where space and mass matter. Its 2W output keeps it in the low-power embedded category.

Is the SPAN02E-03 suitable for outdoor or harsh-temperature use?

The listed operating temperature range is -40°C to +90°C, which supports wide-temperature use. No IP rating is listed in the provided specs, so it should be treated as a protected-environment part rather than an exposed outdoor-rated unit.

How does the SPAN02E-03 compare with the other SPAN02E models?

All SPAN02E versions listed here are 2W constant-voltage converters with the same 21.8 × 11.1 × 9.2 mm size, 2.7g weight, and -40°C to +90°C operating range. The difference is output: SPAN02E-03 is 3.3V at 500mA, SPAN02E-05 is 5V at 400mA, SPAN02E-12 is 12V at 167mA, and SPAN02E-15 is 15V at 134mA.
