We accept PayPal

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, National Semiconductor, Maxim, Burr Brown, 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.

Corona virus - (Covid–19)
During this difficult time and until Government advice changes with regard to small businesses, Soemtron will remain open as usual for our customers to order parts which will be shipped as normal.  We would advise you though to upon receipt, disinfect any packages we have sent just in case it has been contaminated in the postal system.  Exercise care everyone, observe all current guidance about social distancing, hand washing and general health awareness and look out for others in our community.
