EC42 Magnetic Electric Power Transformer Ferrite Core High
Frequency Transformer
1.Product Description
The EC42 Magnetic Electric Power Transformer with Ferrite Core is
engineered for high-frequency applications from 100kHz to 1MHz,
delivering exceptional efficiency up to 96% in compact power
conversion systems. Its EC42 ferrite core (PC40/PC95 material)
minimizes core losses at elevated frequencies, while the planar
winding structure reduces skin effect and proximity losses,
ensuring optimal performance in SMPS, LED drivers, and renewable
energy inverters. With a power range of 100-1000W and isolation
voltage of 3000VAC, it meets safety standards for industrial and
automotive applications. The transformer’s low-profile design and
thermal management features enable operation from -40°C to +125°C,
making it ideal for space-constrained, high-reliability
environments such as EV charging modules and telecommunications
power supplies. Compliant with UL60950-1 and IEC62368-1, this
transformer combines advanced magnetic materials with precision
engineering to deliver reliable, efficient power conversion in
high-frequency applications.
The EC42 Magnetic Electric Power Transformer with Ferrite Core High
Frequency Transformer offers the following key features:
1.High-Frequency Operation
Optimized for 100kHz-1MHz switching frequencies, ideal for modern
SMPS designs.
2.Ferrite Core Material
Uses PC40/PC95 ferrite for low core losses and high magnetic
permeability at elevated frequencies.
3.High Efficiency
Achieves ≥96% conversion efficiency, reducing energy waste and
thermal management requirements.
4.Compact Design
EC42 core size enables a smaller footprint compared to traditional
low-frequency transformers.
5.Low Leakage Inductance
Precision-wound coils minimize leakage inductance (<1% of
primary inductance), improving EMI performance.
6.High Power Density
Handles 100-1000W in a compact form factor, suitable for
power-dense applications.
7.Wide Temperature Range
Operates reliably from -40°C to +125°C, with thermal management
features to maintain performance.
8.Isolation Capability
Provides 3000VAC isolation, meeting safety requirements for
industrial and automotive applications.
9.Planar Winding Technology
Reduces skin effect and proximity losses through optimized
conductor geometries.
2.Features
| Feature | Description |
| Core Material | High-performance ferrite (e.g., Mn-Zn or Ni-Zn) for low losses at
high frequencies. |
| Core Shape | EC42 (E-core with matching I-core), standardized size for compact
power designs. |
| Frequency Range | Typically 20 kHz – 500 kHz+, suitable for SMPS, inverters, and
resonant converters. |
| High Efficiency | Low core loss (low hysteresis/eddy current) and high permeability
at high frequencies. |
| High Power Handling | Designed for medium-high power applications (dependent on winding
and cooling). |
| Low Heat Generation | Ferrite’s low core loss reduces heat buildup compared to laminated
iron cores. |
