IS EMV Impluse transformers: Pulse transformers for SMD mounting
 Environment_Safety RoHS   Environment_Safety China-RoHS

Descriptions

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

- VDE 110b

Applications

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
