Series Data
* Inductance and DCR is for each sideof the winding.
** Based on a 50°C temperature rise from a 70°C ambient and rated current in both windings.
*** Leakage inductance tested as pins 1-2 with pins 3-4 shorted or at pins 3-4 with pins 1-2 shorted.
Windings balanced within 2%.
Dielectric Withstanding Voltage 1250 Vrms ( winding to winding and winding to case on top surface )
For helpful information regarding the data in the following table please refer to the Notes section below the table.
Notes
Operating temperature -55°C to +125°C
Excellent electromagnetic shielding.
Cutom designs available upon request.
Applications include: Reduction of AC line interference produced by switching power supplies, the opposing magnetic fluxes in the core serve to cancel inphase noise signals appearing across the AC line. Also used for noise suppression of DC circuits for switching regulators.
