In comparing the CUI part numbers PJ-002BH-SMT and PJ-002B-SMT the only difference is the letter ’ H '. What does this letter mean?
The letter ’ H ’ that appears in the p/n PJ-002BH-SMT means it can handle a higher current, 5A and a higher voltage, 24VDC. The PJ-002B-SMT is only 16VDC and 2.5A. The PJ-002B-SMT is now obsolete.
