EV35-1.0-02-90M Datasheet/PDFCommon Mode Chokes (CMCs) are electromagnetic components that are used to reduce the amount of noise, or radio frequency interference (RFI), on cables transmitting power or data. They are often referred to as "noise filters" or "isolation transformers." Common mode chokes are usually constructed from two inductors wound around a ferrite or powdered iron core and connected in opposition. Shielding may also be used to reduce capacitive coupling between the windings and minimize electromagnetic radiation.
The EV35-1.0-02-90M is an example of a Common Mode Choke. It is a single-phase, 90-ohm common mode choke designed to reduce noise on current-carrying cables up to 35A. This model is constructed using two separate windings around a ferrite core, with a steel shield for additional isolation. It has a dielectric strength of 1500Vac and a Pulse Current rating up to 30Apk.
The EV35-1.0-02-90M Common Mode Choke works by allowing DC to pass freely through the chokes while blocking any higher frequency signals, such as noise or RFI. This is achieved by creating a magnetic field within the ferrite core of the choke, which reacts to the alternating current and induces a voltage into the windings. This voltage opposes the original voltage, creating an opposing force and cancelling out the higher frequency currents. It also blocks any noise generated by the other components on the board, since the inductor prevents it from reaching other components.
The EV35-1.0-02-90M is often used on AC/DC power supplies, telecommunications equipment, and control panels. It is also used in medical and home appliance applications to reduce the amount of EMI/RFI interference present in the environment. This helps increase the efficiency of the devices and protect against unintentional data leakage.
Overall, the EV35-1.0-02-90M Common Mode Choke is a reliable and effective noise filter for many different applications. It offers excellent noise reduction and isolation capabilities, and is easy to install and use. Its high current rating combined with its durable construction make it an ideal choice for applications that require efficient noise reduction.
