Electronic Products Magazine Selects CDE THA/THAS Thinpack Capacitors as Passive Product of the Year

Cornell Dubilier Electronics, (CDE) described the award winning capacitors as a new development in aluminum electrolytic technology, with very high energy density, in thin-profile packages. The 85°C THA Series Thinpack capacitors are only 8.2 mm thick, while the 105°C THAS Series offers a 9-mm profile. This is comparable in height to surface mount and axial leaded electrolytics, but with much higher bulk-storage capability in a single package.

The THA/THAS components offer very high energy density, up to 1.1 J/cc and up to 0.9 J/cc, respectively. The capacitance range for both series is 60 µF to 18,000 µF with a voltage range of 10 Vdc to 450 Vdc. Unlike traditional cylindrical electrolytics, the THA/THAS capacitors have a laser-welded case which eliminates the need for end-seal gaskets. This sealing method allows for much higher energy density over conventional electrolytics and extends life by preventing the loss of electrolyte.

A single THA/THAS capacitor can replace an array of SMT, axial or radial aluminum electrolytics. That substitution can allow engineers to design smaller products with simplified assembly and higher reliability. In most applications, there are significant cost, weight, and space savings versus a comparably rated bank of SMT or axial aluminum electrolytic capacitors. This can allow a board space reduction of 70%, as well as improved overall circuit reliability, thanks to the lower component count and fewer connection points.

The THA/THAS capacitors are a good fit for a variety of high-performance electronics, including tablets, laptops, instrumentation, commercial-grade LED driver modules, compact power supplies, drones and RPVs, set-top boxes, and 1U rack-mounted devices.
