ICEL specializes in polyester and polypropylene dielectric film capacitors and has manufactured film-capacitor products since 1960. The company supplies both standard and customized capacitors, with product engineering based on the electrical, mechanical and dimensional requirements of the target application. Polyester film capacitors are positioned for general-purpose DC functions such as decoupling, blocking and coupling, bypassing, low-level filtering, timing and noise suppression. Polypropylene film capacitors are used for power and energy applications where low dielectric loss, high current capability and stable performance are important. ICEL identifies UPS systems, inverters and converters, motor control, welding equipment, battery charging, induction heating, medical electronics, resonant circuits and renewable-energy systems including solar and wind as representative applications. The manufacturer provides customization when a standard series does not meet required capacitance, voltage, geometry or mechanical integration constraints. ICEL also publishes General Technical Information that forms part of its product specifications, helping engineers evaluate capacitor technology, application conditions and correct component use. Several series carry approvals from international certification institutes including IMQ, VDE, SEV, UL and CSA, and the company states that its quality-management system is certified to ISO 9001:2015. ICEL products comply with applicable material and environmental regulations identified by the manufacturer, including REACH and RoHS. For power-electronics engineers, film-capacitor selection should consider capacitance, rated voltage, RMS and peak current, dissipation factor, ESR, dv/dt capability, pulse stress, operating temperature and expected lifetime. ICEL’s combination of polyester, polypropylene, power-capacitor expertise and customization is particularly relevant to DC-link, filtering, snubber, resonant and energy-conversion circuits where dielectric technology and thermal loading directly affect system reliability.
