ET2825
INF
The ET2825 uses a high-permeability Mn-Zn ferrite core and precision section winding technology, maintaining low power loss and high impedance even at high frequencies. It efficiently blocks EMI and RFI signals in power lines, preventing operational abnormalities in electronic equipment due to interference.
In terms of electrical performance, the device has a rated voltage of 250VAC, a dielectric withstanding voltage of 2000VAC, and insulation resistance ≥100MΩ, providing reliable electrical isolation. The operating temperature range is -20°C to 105°C, with a maximum temperature rise ≤45°C under normal conditions, enabling long-term stable operation in complex temperature and humidity environments.
It can be used as a general-purpose high-frequency magnetic component to meet the electromagnetic compatibility requirements of LED drivers, audio power amplifiers, and communication equipment.
Professional horizontal structure design, easy for PCB mounting and space layout in compact power supplies
Efficient common-mode EMI/RFI suppression, effectively purifying power signals and reducing equipment interference
Low leakage flux and optimized sectional winding, delivering high self-resonant frequency and low stray capacitance
UL certified design, complying with international safety and EMC requirements for global market applications
