• High-voltage film capacitors manufactured in the UK

• Fully customised specification, form factor, terminal and busbar options

• High volumetric efficiency and current handling

Charcroft Electronics Ltd., - a specialist distributor and manufacturer of electronic components - highlights UK-manufactured custom and high-voltage metallised plastic film capacitors on the Cymru Wales, Welsh Government stand number C3-217 at Cenex Expo 2025.

Used as a DC link in power-conversion battery energy storage systems (BESS), the high-voltage film capacitors are manufactured by Industrial Capacitors Wrexham (ICW), which is a part of Charcroft.

To support carbon reduction, all of the DC-link film capacitors offer full customisation, allowing very high volumetric efficiency and high current handling. Designs provide for low equivalent series-resistance (ESR) and extremely low self-inductance (ESL), which is important for designs using the latest fast switching technology such as Silicon-Carbide (SiC).

The film capacitors offer a range of layout and packaging options to make effective use of available space; terminal options include feed-through terminals which can be bolted directly to a layered busbar or fully integrating a busbar into the packaging to suit the required feed-out. For prototyping, thermal-sensors can be embedded into the package, providing useful system test data

"Covering land, sea and aerospace, the Charcroft ICW custom DC-link film capacitors provide a valuable resource to designers seeking to optimise high-performance electrical powertrain systems where off-the-shelf components require too much compromise."

With full film traceability, the ICW film capacitors also offer the option of complying with the Production Part Approval Process (PPAP) automotive standard. www.icwltd.co.uk

About ICW

ICW has designed and manufactured metallised plastic film capacitors in Wrexham North Wales since 1974, and became part of Charcroft Electronics in 2020. The capacitors are used in power electronics and offer either polyester or polypropylene plastic film, metallised with aluminium or zinc alloys. The voltages offered are from 63Vdc to 2000Vdc, and up to 660Vac, with a capacitance range from 10nF to 2000uF in a single winding, or higher with combined windings. ICW also manufactures ClarityCap™ audio-grade film capacitors. www.icwltd.co.uk
