RS Rectifier 41A. - UK Vintage Radio Repair and Restoration Discussion Forum

Hi folks

I've found in my component stocks an RS REC 41A bridge rectifier. It's RS part number is 261-031. I've looked on-line (including RS On-line) and can't find any information on it. Does anyone have an old RS catalogue with it in it so that I can find out its characteristics. I'm building a power supply (should have finished it yesterday) and it looks about right.

Thanks in anticipation

From the 1972/73 Catalogue:

'Ratings are for capacitive loads at Tamb = 55'C mounted on a heat sink 110 x 110mm 16s.w.g.'

REC41A

100V.P.I.V. If = 1.8A

IFSM = 45A. VF= 2.4V at 2.2A

IRM = 10uA

Thank you so much for producing this spec. so quickly. I read, absorbed and put into use the information you supplied. Was up 'till 02.00 working on the power supplies. All done, finished and tested by about 18.00 this evening ready to install in new launch point bus tomorrow...only two days late. Ironically the new bus is broken and can't be used so I got away with not having the PSUs ready. Folk make decisions, change things but don't always think through the implications of their actions. However, all part of the fun I suppose.

Anyways, thanks again for your speedy reply, very much appreciated,
