Due to the high turnover and processing of products, items ordered may not be in stock. Please contact us prior to placing your order in the event your purchase is urgent and we will advise on the most recent ETA from our supplier.
Should any item(s) included in your order be out of stock, your ordered item(s) will be placed on backorder and you will be notified prior to shipping advising you of your tracking information.
Due to the increasing amount of non API 2520 style op-amps, to protect the proprietary design of our discrete components, and to precisely match and track their use and performance, API has started to serialize each 2520 op-amp with tamper proof labels.
Unique serial number is the proof that op-amp is genuine and customers are welcome to inquire about each op-amp they own, or plan to purchase.
To get an op-amp 2520 order approved, please have the faulty unit serial numbers ready together with the photo of each op-amp.
This photo needs to show the production date stamp (or the original serial number label) and the pins need to be clipped off completely.
