UU9.8 1mh Coils Choke Power Common Mode Inductor

The chip on the PC board is not only an electromagnetic interference object, but also an electromagnetic interference source in the working process. In general, we can divide these electromagnetic interferences into two categories: series mode interference (differential mode interference) and common mode interference (ground interference). Taking the two PCB traces on the motherboard (the wires connecting the components of the motherboard) as an example, the so-called series-mode interference refers to the interference between the two traces; while the common-mode interference is the two traces and the PCB ground. Interference caused by potential differences between lines. The series mode interference current acts between the two signal lines, and its conduction direction is consistent with the waveform and signal current; the common mode interference current acts between the signal line and the ground wire, and the interference current flows through half of the two signal lines. One and the same direction, and use the ground wire as the common circuit.
The common mode inductor is essentially a two-way filter: on the one hand, it needs to filter out the common mode electromagnetic interference on the signal line, and on the other hand, it must suppress itself from emitting electromagnetic interference, so as to avoid affecting the normal operation of other electronic devices in the same electromagnetic environment.

Product performance:
1. Entirely wrapped in UL heat shrinkable sleeve.
2. Large inductance range.
3. Good stability.

Performance
1. Working frequency: generally work under 20kHz-500KHz
2. Operating temperature: The temperature should be between -40℃ to +125℃, otherwise it may affect the use of the inductor.
3. Storage temperature: storage temperature -25°C to +85°C to avoid inductance aging
