Looking for data on this device if anyone has an old Philips databook PA02 from 1960 - 80's era, well before Philips Components became BC Components and subsequently Vishay aquired it. Vishay deleted some of the 2322-662-91* series thermistors but I don't know which ones and when. They later changed the 2322 part to 2381 on the remaining PTC items and later deleted all degaussing devices ending in 96***.
