Product Overview

The EI33 (6+6) high frequency transformer is developed for power systems that require higher energy throughput and enhanced electrical stability. Featuring a larger ferrite core compared to EI30, it supports improved magnetic capacity and is well-suited for high-power switching applications such as SMPS, inverters, and industrial power modules.

Mechanical Integration & Mounting

The EI33 (6+6) transformer is designed for efficient integration into PCB-based systems:

Standard DIP mounting for secure installation
Consistent pin layout for automated assembly
Compatible with vertical or horizontal configurations

Its mechanical stability ensures consistent performance across production batches.

Typical Applications

Industrial power supplies: Power systems for guide rail power supplies and industrial automation control boards.
Inverter power supplies: High-voltage boost stages in applications such as vehicle inverters and UPS uninterruptible power supplies.
High-power home appliances: Main control board power supply for induction cookers and high-power rice cookers.
Inverter welding machines: Used as auxiliary power transformers to provide stable power for the control circuits of welding equipment.
