Passive Components
Supprescraft has been manufacturing passive components for the South African electronics industry since 1974. Based in Selby, south of Johannesburg, the company has made significant investments in manufacturing technology and equipment in order to remain competitive in this high volume market. Driven by customer requirements for quantity and quality, the company is able to offer products manufactured to IEC standards and competitively priced by world standards. Manufacturing a wide range of capacitors, magnetic devices, surge protection devices and a range of mains filters, Supprescraft quality tests each and every component for stringent performance characteristics.
Supprescraft produces metallised film capacitors using polyester, polypropylene and polycarbonate dielectrics. Construction types are radial solid lead box, radial flexible lead box, radial solid lead dipped, and cylindrical and radial bracketed box capacitors. They are manufactured to IEC 384 standards and can be custom-produced to the AC/DC voltages required. Specialising in small batches with short turnaround times, the Supprescraft range of capacitors covers values of 0,001 μF to 10 μF at 63 to 630 V d.c., as well as 275 V and 500 V a.c. for use in x and y suppression applications. Lighting capacitors are also produced up to 10 μF. Radial capacitors are made with lead spacing from 10 to 27,5 mm.
Supprescraft's winding facility produces a range of magnetic devices using ferrite, powder iron, silicon and nickel core materials. Toroidal devices - chokes, dimmer coils, common mode and single wound inductors and current transformers from 10 mm ranging to 78 mm OD and 1 to 30 A - are manufactured to IEC standards. E, EFD and ETD type transformers are constructed in sizes from 10 to 49 mm. RM devices are produced from RM 5 up to RM 8, while P core transformers are produced up to 30 mm. Transformer safety requirements are met with the use of borders, margins and triple insulated wire when specified. All transformers are 100% tested for turns ratio, phasing and insulation breakdown. Bead, rod and air core, as well as proximity chokes and coils are wound and tested.
