Electronic store FIRMA PIEKARZ

Firma Piekarz is a wholesaler of electronic and electrotechnical parts and materials for electronics. We also manufacture aluminum heat sinks. Almost all of our goods are new and repetitive parts. We do not specifically look for cheap bargains and we pay great attention to the quality of the products we offer.

The vast majority of our sales are made by mail order through our online store. At our headquarters it is possible to pick up orders.

We try to complete placed orders as soon as possible, most of them are shipped within 1 working day. For our customers, we also deal with the completion of deliveries and sourcing of items that we do not have in stock.

Our wide range of products includes semiconductors, switches, enclosures, sensors, safety components, connectors and much more. We encourage you to check out new items, or our bestsellers. A sizable portion of our products are imported in-house, so we can offer them at very competetive prices.
