Rectangular Power Capacitors for DC-Link & DC Filtering Applications

In case of High Power Capacitors, TDK offers different solutions for DC-Link and DC-Filter applications. We are actually offering a wide spectrum of capacitors with resin filled plus opened cases specially designed for LV, ModCap™ as standard solution and MKK-DCR as a customized one. On the other hand, we may offer sealed cases for those applications with aggressive environmental conditions and specially strict operation requirements (current and temperature), either in Oil-impregnation or in Polyurethane resin as a dry option.

Benefits

Compact power unit

Thanks to our rectangular geometry and to our flat winding technology we are able to provide the most efficient solution in terms of volumen and weight.

100% customized solution

Our PEC HP designs are 100% customized as per customer requirements and all of them approved according to IEC 61071.

Hermetically sealed

Our Stainless Steel rectangular cases allow us to assure a maximum level of sealing.

Lifetime up to 200,000 h

Based on the most innovative design rules TDK assures extended Lifetime in all our technologies.

Compatible with Pressure Switch device

Our sealed designs are fully compatible with last generation of pressure switch devices.

Open Design

TDK offers as well open designs with Aluminium case specially suitable with low inductance requirements.

ANSYS™ simulations available

Thermal & Mechanical models available for specific simulations according to spectrum and boundary conditions defined by the customer.

Flat windings

TDK is pioneer on flat winding design and selected this technology for PEC HP series thanks to its excellent self healing properties and ultra compact design.
