Common Mode Chokes are electromagnetic components used in electrical circuits for the purpose of suppressing electromagnetic interference (EMI), which comprises both conducted and radiated inferences. Common mode chokes are commonly found in high voltage circuits, such as those used in telecommunications systems and medical equipment where high voltage signals must be suppressed due to safety regulations.

The SS21V-200024 series common mode choke modules from Schaffner Inc. offer exceptional performance and assurance in EMI protection in a number of applications. The SS21V-200024 series is available in both vertical and horizontal mounting options, with a rated current range up to 100A in both. The size and shape of the common mode chokes can be customized to fit in various enclosures and equipment. The module is comprised of a ready-to-use PCB substrate, with two separate windings around a common core. The module has an operating temperature range of -40°C to +125°C, and a UL94V-0 flammability rating.

The SS21V-200024 series common mode chokes are mainly used in industrial applications in such fields as medical technology, lighting, industrial automation, HVAC, power supplies, and more. Medical equipment, for example, requires common mode chokes to ensure safety from high voltages and also to reduce EMI noise from other electrical equipment nearby. Furthermore, the common mode chokes reduce EMI-induced high frequency signals, which can also be used to reduce EMI-radiated signals from within the device itself.

The SS21V-200024 series common mode chokes employ a Ferrite core, which consists of two windings wound around the core in opposite directions. This is known as common-mode winding, and works to reduce the common-mode noise voltage that exists between the two ends of the choke. The common-mode noise voltage is effectively lowered by a factor of two when the windings are used, as the noise voltage is divided between the two windings. The choke also works to prevent common-mode current from flowing through the wires, as the windings create an inductive choke, which acts as a "resistor" for current, creating a low-impedance path for the noise current. This also helps to reduce noise on the power line.

In addition to their use in medical technology, the SS21V-200024 series common mode chokes are suitable for use in any power source where they might be exposed to EMI noise, and can be used in high power applications such as motor drive and smart grid technology. The chokes are also designed to perform in a wide range of temperatures, from -40°C to +125°C, allowing them to be used in a variety of climates and locations. Finally, the common mode chokes also provide an integrated solution to EMI suppression, with no additional components or components required.

The SS21V-200024 series common mode chokes from Schaffner Inc. are designed to provide superior performance and to ensure EMI protection for a variety of applications. With their wide range of power handling capabilities, high temperature range, and easy installation, they offer a comprehensive solution to EMI problems in both medical and industrial applications.
