Conductive Polymer Aluminum Electrolytic Capacitor

Notes

The OST PUS series is listed as conductive-polymer aluminum electrolytic. OST was an official TOSHIN distributor, and its product pages also featured TOSHIN solid capacitors; this can cause confusion. The source does not conclusively identify the actual manufacturer of OST's own solid product.
