ET2835
INF
The ET2835 employs a high-permeability Mn-Zn ferrite core and precision section winding technology, maintaining low power consumption and high impedance even at high frequencies. It effectively cuts off the conduction path of EMI and RFI signals, 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 excellent 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 continuous 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.
Outstanding high-frequency impedance characteristics, providing stable filtering performance in broadband interference scenarios
High dielectric withstand voltage up to 2000VAC and ultra-high insulation resistance for enhanced safety
Wide operating temperature range and low temperature rise, ensuring long-term stable operation under continuous load
