Common mode chokes (CMCs) are essential components for power electronics and motor drives, providing optimized performance in terms of efficiency, power losses, and electromagnetic interference (EMI). When these components are applied in applications such as inverters, drives, frequency changers, and energy converters, they can offer high common-mode current, low isolation resistance, and wide operating temperature range. This makes them ideal for many switch-mode as well as linear pulsed modulated motor drives.The UU9LFNP-B103 is a differential mode choke that has been designed for use in high-power applications. It is constructed from ferrite cores and has a rated input voltage of up to 3kV. The device is also capable of operating over a temperature range of -40°C to +150°C.The UU9LFNP-B103 is a DC choke designed for use in electrical motor drives in order to reduce harmonic and radio frequency interference (RFI) and other forms of power noise. The choke works by introducing an impedance to the motor drive circuits in order to restrict signals of a certain frequency range from passing through the wiring. This effectively reduces the RFI noise generated in motor drive applications.The UU9LFNP-B103 is designed to be compact and lightweight and is designed for use in harsh environments. The choke is rated to have a leakage current of less than 500nA and is suitable for switching frequencies up to 500kHz. The low leakage current ensures a low interference of the downsizing frequency drive and its wide operating range ensures reliable operation and control over a wide range of motor speeds.The device is also designed to filter high-order harmonics, which can be produced from the PWM (pulse width modulation) control of the motor drive system. The device can also be used to filter out common-mode noise. This is done by placing the neutral(s) of the output cable in between two common-mode filters. This reduces the amount of noise that is coupled through the common-mode of the cable and onto the motor drive system.In addition, the UU9LFNP-B103 is designed to reduce the external noise that is generated by motor drive applications. This is achieved by using materials with an excellent thermal conductivity, which is effective in dissipating heat away from the core. The efficient dielectric material and advanced ferrite core construction ensures that the UU9LFNP-B103 is capable of providing excellent common-mode noise attenuation.Overall, the UU9LFNP-B103 is an ideal component for many types of motor drive applications. Its compact size and wide temperature range make it suitable for use in a wide range of demanding environments. The device can also be customized according to customer needs, allowing for the use of specific materials to suit different performance requirements. Additionally, its low leakage current ensures a low interference of the downsizing frequency drive, while its wide operating range ensures reliable operation and control over a wide range of motor speeds.
