Evans Capacitors – Product announcement: HyCap Capacitors
The capacitors are comprised of sintered tantalum anodes and ruthenium oxide coated cathodes operating in aqueous electrolyte. The components are confined by a compressed gasket, followed by a hermetically welded glass to metal seal.
The capacitors are hermetically sealed such that the package does not leak electrolyte or vent any gas when exposed to a vacuum, per MIL-STD-202, Method 112, Condition C, Procedure IIIa.
Operating temperature is -55°C to +125°C (with voltage de-rating) and storage temperature -62°C to +130°C.
HC4B and HC4D ratings in both standard temperature and high temperature versions.
