Applications: 1. common mode noise suppression, 2.EMI harmonic filter and various EMC products
Performance characteristics: 1. fewer turns, higher inductance can be obtained;
2. low distribution capacitance;
3. high resonance frequency;
4. smaller size;
5. temperature rise low;
6. can be used for long periods at higher operating temperatures
