MEGGITT CGS HIGH VOLTAGE RESISTORS HIGH VALUE RESISTORS HIGH POWER RESISTORS ALUMINIUM CLAD RESISTORS CURRENT SENSE RESISTORS High Power Resistor TYPE SBC (SQUARE CERAMIC) SERIES This range of Power Wirewound Resistors are wound on continuous glass fibre elements or have a ceramic core depending on resistor value. The element is housed in a ceramic case and sealed with an inorganic silica filler. Their construction gives a resistor with high insulation resistance and low surface temperature, capable of withstanding high overload currents. These resistors are ideally suited to a variety of applications within industrial and commercial environments, where performance and reliability are of prime importance. Applications include fan force ovens, cooker hoods, power supplies and triac based speed controls. Custom Design Variants in value and style are welcomed. MEGGITT CGS KEY FEATURES UP TO 17 WATTS FUSIBLE STYLES VERTICAL OR AXIAL NON FLAMMABLE SPECIAL SOLVENT RESISTANCE ATTRACTIVELY PRICED CUSTOMER SPECIALS INVITED WIDELY AVAILABLE FROM DISTRIBUTION MEGGITT ELECTRONIC COMPONENTS SALES ACTION DESK TEL: (01793 611666) FAX: (01793 611777) EMAIL: [email protected] WEB SITE: www.megelec.co.uk LOG No FO420 ISSUE 10 4 Pages 02-00 SPECIFICATION (cont...) TYPE SBC SERIES Page 2 of 4 CONSTRUCTION A range of flame-proof wirewound resistors with excellent electrical and mechanical characteristics. The resistance wire is wound on a fibreglass or ceramic core and protected by a ceramic body. This construction combines good thermal characteristics with high insulation resistance, and gives good physical protection. Lead length allows vertical or horizontal mounting.

These are for additional heat dissipation and vertical mounting of resistors. The suffix for each style is as follows:SBC Standard SBCH 4/5/6/7 SBCH 8/11/15 TYPE SBCHE (For Vertical Mounting) We offer SBCHE Styles with one lengthened lead for vertical mounting. See additional hardware on last page. Lead Length 20mm longer than case length. Supplied with one longer lead wrapped back in flute in ceramic. SPECIFICATION (cont...)
