Pulse transformers for SMD mounting
Approvals and Compliances
Description
- High insulation rating (>3.2 kVAC) between the primary and the secon-
dary 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 elec-
tronics
- The defined partial discharge voltage guarantees an effecively unlimited
serviceable live
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
