Toroidal Transformer - China
price: contact company for price
1 - High Efficiency
Seamless toroidal core (ferrite/powdered iron) minimizes core loss (<1.1W/kg) and achieves >95% efficiency.
Low no-load current (<10% of laminated transformers).
2 - Low EMI/Noise
Closed magnetic path reduces flux leakage (<0.1% typical).
Vibration-free operation (<20dB at full load).
3 - Compact Design
50% smaller/lighter than equivalent EI-core transformers (e.g., 40×75mm/0.6kg for 50W).
4 - High-Frequency Operation
Optimized for kHz–MHz range with Litz wire windings to mitigate skin effect.
5 - Thermal Reliability
