Working Principle of RN216-0.5-02-39M

RN216-0.5-02-39M is a common mode choke which works by blocking differential mode signals while allowing common mode signals to pass through. It does this by using two coils wrapped around two different cores, with one being a high-permeability ferrite core and the other being a low-permeability air core. As the two coils are wound in such a way that one coil carries the common mode signal while the other coil carries the differential mode signal, the differential mode signal is heavily attenuated while the common mode signal passes through.

The ferrite core of RN216-0.5-02-39M acts like an inductor which has a high impedance at low frequencies, while at higher frequencies, the inductor will start to become saturated and its impedance will drop. This reduces the amount of differential mode currents that can pass through and thus effectively suppresses EMI at higher frequencies.

Conclusion

RN216-0.5-02-39M is a high-performance common mode choke which can be used in a variety of applications. It works by blocking differential mode signals while allowing common mode signals to pass through. The ferrite core of RN216-0.5-02-39M acts like an inductor which has a high impedance at low frequencies, while at higher frequencies, the inductor will start to become saturated and its impedance will drop which helps suppress EMI at higher frequencies.
