ET2432 Common Mode Power Line Choke / EMI Line Filter

The ET2432 selects high-permeability Mn-Zn ferrite as the core magnetic material, combined with improved structural design and precision section winding technology. While enhancing high-frequency operating performance, it significantly reduces the adverse impact of power loss and stray parameters on the circuit system, and possesses excellent electromagnetic compatibility (EMC) protection efficiency. As a key interference suppression component in the power supply system, this device can effectively cut off the conduction path of EMI and RFI signals, avoid operational abnormalities of various electronic equipment caused by interference, and is widely applicable to switching power supplies, EV chargers, LED driver modules and EMI/EMC filtering circuits and other multi-application scenarios.

In terms of electrical performance, the ET2432 has a rated voltage of 250VAC, a dielectric withstanding voltage of 2000VAC, and a minimum insulation resistance of 100MΩ, featuring excellent electrical insulation performance that can effectively prevent leakage hazards. The operating temperature range is from -20°C to 155°C, and the maximum temperature rise under normal operating conditions is controlled within 45°C, enabling long-term uninterrupted operation in complex temperature and humidity environments. The primary inductance of some models ranges from 1700uH to 3000uH, which can accurately match the inductance parameter requirements of different circuits, while balancing low-power characteristics, helping to improve the energy efficiency and operational stability of the overall circuit system.
