Product information "EC Series Film Capacitors"
Cornell Dubilier CDE (formerly NWL)’s EC-Series metalized polypropylene DC link film capacitors offer large capacitance values, high Joule energy, and large current ratings in a single welded metal package. This dry resin filled package can have a variety of low inductance terminal options, brackets for mounting, and can also incorporate additional metal structure to accommodate additional components such as resistors, chill plates, etc.
EC-Series capacitors are well suited for many inverter applications including:
- DC input / output filtering
- DC Link
- AC harmonic filtering
- High energy storage pulse
- Traction drives and heavy vehicles
Unique features of the EC-Series capacitor include:
- Large Capacitance values at high voltages – By utilizing fabricated welded metal packages, Cornell Dubilier CDE can incorporate large capacitance values with the higher voltage ratings.
- Rugged metal cases – Welded metal cans fabricated from alum, brass, steel, and stainless steel are provided for rugged packages up to 500 lbs.
- Inverter design flexibility – With an already fabricated metal package, Cornell Dubilier CDE can fasten onto the metal container unique brackets to accommodate a variety of functionality.
Knowles Corporation is a global provider of high performance capacitors and radio frequency (RF) products, balanced armature speakers, advanced micro-acoustic microphones, and audio solutions. The Company's segments include Precision Devices (PD), and Medtech & Specialty Audio (MSA). The PD segment specializes in the design and delivery of high-performance capacitor products and RF solutions primarily serving the defense, medtech, electric vehicle, and industrial markets. The MSA segment designs and manufactures balanced armature speakers and microphones used in applications that serve the hearing health and premium audio markets. The Company sells its products directly to original equipment manufacturers (OEMs) and to their contract manufacturers and suppliers and through distributors worldwide.
Knowles also continues the legacy of NWL and Cornell Dubilier Electronics (CDE) with a broad portfolio of advanced capacitor technology that is used in demanding industrial applications, e.g., custom, high-voltage DC and AC film capacitors for pulsed power and power conversion applications, including water-cooled devices, capacitors for fast switching IGBTs, DC link capacitors, air-cooled capacitors for harmonic AC or high-voltage DC filtering, DC filter and DC pulse capacitors or oil-filled capacitors for pulse power and power conditioning applications.
