You are purchasing a bulk lot of 11 x International Rectifier GBPC3508W bridge rectifiers. These are rated 800 volts and 35 amps.
The rectifiers are brand new old stock so there is some slightly bent pins and tarnish from storage. They are supplied on individual foam squares as pictured.
New price from Farnell is around $10 each so this is your chance to stock up at a bargain price! Any questions please don't hesitate to ask. Happy to combine postage with other items.
