Description

Pulse Transformers IT series with double secondary winding

The IT series pulse transformers provide galvanic isolation between drive and power circuits, offering voltage resistance up to 4 kV and ignition currents up to 1 A. With turns ratios up to 3:1:1, these transformers are suitable for a wide range of applications including gate drive circuits, power supplies, power converters, frequency converters, switching applications, DC/DC converters, and line coupling transformers in high-speed data transmission. Key advantages include high potential difference voltage scaling, vacuum potting for very low partial discharge effects, and PCB through-hole mounting. Custom-specific versions are available upon request.

* Tolerance for Lp: +50%; -30%

Explanations:
tr rise time at given load resistor R and 70% of the output pulse height.
Lp primary inductance measured at 1 kHz (secondary coil open).
Lstr stray inductance measured at the secondary side, short circuit at the primary side. If there are several secondary coils only one at the time is connected (measuring frequency 10 kHz).
The ignition current is a set peak value where the voltage drop over the coil resistance is still insignificant (mostly below 1 V).
