To make a purchase or request further information, please us.
All prices are per item plus postage in U.K. pounds, £2.50 minimum order + postage + fees, payment by PayPal with your order. For international orders please enquire about shipping costs and exchange rates.
If known, the manufacturer or supplier is listed in the item description (FEC: = Farnell, RS: = RS Components, MuRata, Traco Power, MeanWell, Etc.). N.O.S. = New Old Stock, new unused parts in their original packing where possible, but may have bent leads, the packing may be degraded (E.G. bandolier fed components). All semiconductor parts are stored and supplied in anti-static packaging. All components are supplied untested as we do not have any facilities to do so.
