Low-profile aluminium electrolytic capacitor breaks energy density barriers

New Yorker Electronics has released a new development in aluminium electrolytic technology from Cornell Dubilier Electronics. The new CDE 85C THA Series ThinPack capacitors are only 8.2mm thick, and only 9mm in the 105C THAS Series. Comparable in height to V-chip electrolytics, tantalums and board-mounted axials, the THA and THAS offer much higher bulk-storage energy density. A single THA/THAS capacitor can replace an array of SMT, axial or radial aluminum electrolytic or solid tantalum capacitance arrays. That substitution can allow engineers to design smaller products with simplified assembly and higher reliability. The THA/THAS Series design is radically new, yet based on CDE’s 20+ years’ of experience with MIL-grade flat electrolytics. Re-engineered to be thinner and more cost effective, it is a good fit for many of today’s high-performance electronics. Unlike traditional cylindrical electrolytics, a THA/THAS capacitor has a sealed, laser welded aluminium case that eliminates the need for space wasting end seal gaskets. The design includes a valve to vent hydrogen gas, reducing swelling by relieving internal pressure. Suitable applications include any circuits that require high capacitance bulk storage and filtering in a low-height profile. This includes tablets, laptops, instrumentation, commercial-grade LED driver modules, compact power supplies, drones and RPVs, set-top boxes, 1U rack-mounted devices and other thin, high-performance devices.
