IS Pulse Transformers www.schurter.com/pg85 Pulse transformers for SMD mounting Description -High insulation rating (>3.2 kVAC) between the primary and the secondary windings -High insulation rating up to 500V between the secondary windings -Small coupling capacitances between primary and secondary windings limit transient feedback from the power supply side to the control electronics -The defined partial discharge voltage guarantees an effecively unlimited serviceable live Standards -Galvanic separation of drive- and power-circuit -Mainly used in ignition circuits with Thyristors, Triacs, power transistors and IGBT's -DC/DC converters -Line coupling transformers in high speed data transmission References General Product Information Weblinks Approvals, RoHS, CHINA-RoHS, e-Store, Distributor-Stock-Check -VDE 110b Technical Data Rated voltage Voltage Time Integral Pulse Rise Time Turns Ratio Terminal technic Weight Material: Housing Sealing Compound up to 600 VAC 150 - 400 Vµs 0.05 - 1.5 µs 1:1, 2:1, 1:1:1 SMD 3 - 10 g UL 94V-0 UL 94V-0 Climatic Category Allowable Operation Temp.
