Common Mode Chokes

RN122-0.8-02-39M is a type of common mode choke which is widely used in a variety of applications. This type of choke is made up of a number of coils with varying resistances and inductances, which are wound around a core or bobbin. This provides inductance and resistance to a signal passing through them, allowing the elimination of common mode noise from a signal. This type of choke is often used in power supplies, in-circuit testing, power distribution units, and other applications.

The RN122-0.8-02-39M common mode choke is designed to pass signals with low loss while blocking common mode noise. It consists of two separate coils: the primary coil and the secondary coil. Both are made with a high resistivity material. The primary coil is usually enclosed in a shield or case, which reduces the amount of interference by preventing any electrical current from entering or leaving the coil. The secondary coil is then placed in the center of the primary coil, and this coil is designed to induce an opposition to any signal current which passes through the primary.

The electrical current induced in the secondary coil will oppose any current in the primary coil. This opposition will cause a drop in the electrical signal passing through the choke. The resistance and inductance offered by the RN122-0.8-02-39M common mode choke is measured in Ω and mH, and this is usually dependent on the type of core and winding setup used. The exact resistance and inductance of the common mode choke will often be specified in the product datasheet.

The RN122-0.8-02-39M common mode choke is used to filter out common mode noise from the signal. Common mode noise is any electrical current which flows between two parts of a signal path that have different impedance levels. This type of noise can reduce the performance of a circuit, and thus must be filtered out if the circuit is to operate correctly. The RN122-0.8-02-39M common mode choke will provide the necessary impedance mismatch to help reduce the amount of common mode noise present in the signal.

The RN122-0.8-02-39M common mode choke also offers other advantages. It can be used as a barrier for high frequencies, as it will attenuate the signals above a certain frequency. Additionally, the choke can be used as an isolator, as it will add a separate and isolated current path to the signal. This can provide protection against electrical surges, EMI, and RFI.

Overall, the RN122-0.8-02-39M common mode choke is a versatile and effective solution for filtering out common mode noise from signals. It provides excellent performance at a relatively low cost, and is suitable for a wide range of applications. As such, it is an excellent choice for those looking for a reliable and cost effective way to reduce noise in their circuits.
