Frequently Asked Questions

What is the input voltage range and output power rating of the SCWN03B-03 DC-DC module?

The SCWN03B-03 accepts an input voltage from 18 V to 36 V with a 24 V nominal, and delivers up to 3 W of regulated DC output power. Conversion efficiency reaches 82%, which limits self-heating and simplifies thermal management in enclosed industrial enclosures.

How does the DIP-24/8 package of SCWN03B-03 simplify integration into industrial PCB designs?

The DIP-24/8 (R-PDIP-P8) through-hole package of the SCWN03B-03 enables direct PCB insertion without SMT reflow, allowing easy manual assembly or socket mounting. This is especially practical in industrial control boards where field serviceability and component replacement are important considerations alongside the 18 V to 36 V operating range.

What regulatory approvals does the SCWN03B-03 carry and why does this matter for procurement?

The SCWN03B-03 carries EN and IEC approvals, confirming compliance with European and international safety and electromagnetic standards. For procurement teams sourcing this 3 W DC-DC module for industrial or medical-adjacent applications, certified approval status reduces qualification burden and time-to-market for regulated markets.

Should buyers plan for extended lead times when ordering the SCWN03B-03 in volume?

Yes. The SCWN03B-03 has a factory lead time of approximately 19 weeks for volume orders, which is significant for production planning. Procurement teams should place orders well in advance or maintain safety stock, particularly for applications relying on this 24 V input, 3 W regulated DC-DC module in long production runs.
