Can someone identify this component ? It has markings 8110, 15 V, 100, 10% and the PC board is marked - and + .Those are the pictures. Thank you for your help. ![Unknown Component](https://global.discourse-cdn.com/digikey/original/3X/b/f/bfb9fa1d26c59328cf64a6e2f8885460b5daa4fa.jpeg) ---

Hello bogdan, Welcome to the DigiKey TechForum! In analyzing both the pictures and the information you’ve provided, I believe you have a capacitor. The 15V would be the maximum voltage. 10% would be the tolerance of the capacitor. The 100 would likely be 100uF, and the + and - symbols would indicate the polarity. The 8110 is what throws me off, as I’m not sure where that would necessarily fit into it. Do you happen to have a measurement of a fully intact one? It may be helpful to know what this came off of as well. > **[Capacitors | Tantalum Capacitors | DigiKey Electronics](https://www.digikey.com/en/products/filter/tantalum-capacitors/59?s=N4IgjCBcoMxaBjKAzAhgGwM4FMA0IB7KAbXBgBYAGEAXXwAcAXKEAZUYCcBLAOwHMQAX3xgAbPBBJIaLHkIkQMMAHYwATmp0QTFu278hItQA41EqTJz4ikUpuEgATJXJnoklBivzb4SgAIAVoAxEBFKAJDaBmZIEABVHi5GAHlkAFlsVEwAVw5sQydKZTdET1lrBTAAVn8ANWjtWISk1Iys3PzCgFpSj0hOHLkbUggaB27HcyhB4YVq2kEloA)** > > Tantalum Capacitors are in stock at DigiKey.

Likely a date code; 10th week of 1981 would seem consistent with the odd construction. [30D107G015DC2A](https://www.digikey.com/en/products/detail/vishay-sprague/30D107G015DC2A/5609451) might be another less costly option. ---

Thank you for the info. The manufacturer is Quality Measurement Systems. The counter is model Quality 800. ---

Hi @bogdan , It is amazing that a “non-antique” looking equipment (Quality 800) contains such a discrete that, based on appearance, could easily be from a WWII era radio. It is probably a “wet-tantalum” cap (made by Sprague?), as anticipated by @Klint_12443, @rick_1976 . Something close to this: > **[500D107M050DH5](https://www.tedss.com/2020097273)** > > 500D107M050DH5 SPRAGUE capacitor 100uF 50V aluminum electrolytic axial 2020097273 It is fairly safe to attempt to replace it with another 100uF cap, as it is unlikely that the rating and cap type is critical. Just for fun, could you provide a photo of the PCB where the component was seated in? Cheers, heke ---

bogdan, Good luck with the repair. Please keep us posted on the results. ---

Hi @bogdan , What a wonderful piece of art! I assume that the suffered cap was located to just above the display cubicles. If so, the cap is obviously for filtering the supply ripple due to LED multiplexing, therefore about any type of capacitor will do. It is OK to place it on the other side of the board too, if space restricts/allows. Cheers, heke
