Description
ETD49/25/16 10+10 PIN High Frequency Ferrite Switching Transformer
Product Overview
ETD49/25/16 10+10 pin SMD high frequency transformer adopts low-loss manganese-zinc ferrite magnetic core, with cylindrical center column design for easier winding and larger winding cross-section to boost output power. ETD39 and ETD59 types are also normal type of ETD series.
This series features stable performance, low temperature rise, wide working frequency range, moderate cost and high long-term reliability. Compatible with full-bridge, half-bridge, single-ended, resonant and push-pull switching circuit topologies, widely matched with PWM driver IC, MOSFET and SMD power inductors for complete switching power supply solutions.
