New CLS 105°C Flatpack™ Capacitors Expand Knowles’ Cornell Dubilier Product Line
Type CLS capacitors, developed by Knowles’ Cornell Dubilier brand, are engineered for low-profile, high-density power supplies that don't require an extreme temperature rating. These new Flatpack™ aluminum electrolytic capacitors expand the existing product line, offering a 105 °C temperature rating that positions them between the 85 °C MLPS and 125 °C MLSG series.
Building on the established MLPS and MLSG capacitor series, the CLS Flatpack™ capacitors deliver high capacitance density in a compact footprint. Their 105 °C rating is supported by a robust endurance testing specification of 10,000 hours at this temperature, ensuring the reliability required for their target applications without the overhead of a 125 °C rating.
The 105 °C-rated Flatpack™ capacitor features a stainless-steel construction. This design choice is crucial for delivering enhanced thermal dissipation, which in turn contributes to higher efficiency, improved overall performance, and a longer operational lifespan for the component. The product is ideally suited for applications where a compact form factor and high capacitance density are paramount, but an ultra-high temperature rating is not a critical requirement.
The entire Flatpack™ line, including Type CLS, MLPS, and MLSG capacitors, is characterised by its durable construction, making it a reliable solution for demanding applications. Their rugged design ensures stable operation even when subjected to vibration, shock, and high ripple currents. Furthermore, the Flatpack™ series offers a variety of low-profile stainless-steel case sizes and multiple mounting options, enabling engineers to efficiently integrate bulk capacitance into a single, compact unit.
