This document describes the specifications and characteristics of CDM Cornell Dubilier's Type 7P 55°C high-energy, long-life aluminum capacitors. These capacitors have a lifespan of over 100,000 full discharges, which is more than ten times the life of ordinary photo flash capacitors. Additionally, the Type 7P capacitors have industry-leading energy densities of over 1 joule per cc.
The Type 7P is a rugged aluminum photoflash capacitor designed for high‑energy, long‑life applications. It can endure more than 100,000 full discharges, offering an industry‑leading energy density of over 1 joule per cc thanks to a special high‑energy anode foil.
Key specifications include a wide operating temperature range, high rated voltage options, and a variety of capacitance values. The part features snap‑in or solder‑lug terminals and complies with RoHS requirements. Detailed terminal drawings, part numbers, and mechanical dimensions are provided for easy integration.
