SDF DF104S

SDF Thermal Cut-Offs SDF Our Thermal Cut-Offs (Organic Thermal Element Type) are used to prevent fires caused by abnormal heat generation from circuits and other heat producing electrical products. They are a non-resettable thermal fuse which open electrical contacts when temperatures exceed the specified level. Operating Principle When the ambient temperature rises to the functioning temperature, the thermal element melts and the springs move the contact away and open the circuit permanently. Applications Approvals UL & cUL: E117626 VDE: 115369, 116219 PSE: JET2926-32001-1001-1009 CCC: 2003010205079617 EK: HH05009-2004A-2019A Dimensions • Electric home appliances and heating devices • Coil-winding products and power supplies • Office equipment and telecommunication devices • Automobiles & other electronic components Cautions • Bends in leads should be at least 3mm from the body of the TCO. • Extreme caution must be used while soldering, use a heatsink and avoid heating above Tf -24°C. • The metal portion of the TCO is electrically live and may require insulation. • Do not use in liquids or poisonous gasses such as sulfuric acid or nitrous oxide. • Do not connect heater directly to the cutoff.
