They’re certified to AEC-Q200 Rev. E and designed for operation from -40 °C to +150 °C, assembly the reliability necessities of automotive purposes.
E13 EM
The E13 EM sequence incorporates a compact SMD design constructed on a MnZn ferrite core. With a footprint of 18.6 x 14.6 mm and a peak of as much as 12 mm, the parts help typical working frequencies between 100 kHz and 400 kHz.
They’re out there for both flyback or push-pull topologies.
They’ve inductance values starting from roughly 1.8 µH to 240 µH and saturation currents of as much as 9 A. This, says TDK, permits design flexibility throughout varied energy architectures.
Creepage and clearance
The corporate highlights that the E13 EM sequence meets stringent creepage and clearance necessities, for protected and environment friendly energy conversion in xEV platforms.
Particularly, the transformers have creepage distances of as much as 6.3 mm and clearance distances of as much as 5.5 mm and meet the necessities for fundamental insulation at 500 V (DC) and strengthened insulation at 300 V. That is compliant with IEC 60664-1 and IEC 61558-2-16.
The parts are specified for transient overvoltages as much as 2500 V and a partial discharge extinction voltage of 900 V.
Doable applciations embody remoted DC-DC converters (flyback and push-pull topology) and AC-DC energy provides. And in addition gate drive transformers for IGBT/MOSFET xEV inverters and auxiliary energy methods.
