Common mode chokes are one of the most important components in electronic circuits. A common mode choke, also known as a differential-mode choke, is an inductor specifically designed to reduce common mode interference with high frequency signals. The ALFT-03A-7 is a common mode choke designed to filter differential mode signals from one side of a power line to the other and is suitable for applications in high speed, precision electronics.The ALFT-03A-7 is constructed with a pair of opposed coils wound from N80 core material. The core is a ferrite material and is designed to help reduce eddy currents in the device. The two windings are then intertwined and the device is then wrapped in a high temperature PVC insulation material. A square-shaped mounting bracket is used to mount the device which helps to keep it firmly in place during operation.The ALFT-03A-7 has an overall size of 31x31x16mm and a weight of 16.5g. It has a maximum operating temperature of 125°C and a voltage rating of 250V AC. It also has a current rating of up to 0.5A, with a maximum input impedance of 160Ω and a minimum impedance of 8Ω. The device has an insertion loss of 27 dB at 10MHz, with a frequency range of up to 250MHz.The primary application of the ALFT-03A-7 is in high speed, precision electronics, such as in radio frequency (RF) signal circuits. It can be used to filter out noise from power lines, and to help protect sensitive components from the effects of disruptive noise. The device can also be used to help reduce the radiation of noise from electronic equipment, and to limit the amount of heat generated in a system by reducing the voltage and current levels of signals passing through it.The working principle of the ALFT-03A-7 is based on inductors, which create an electromagnetic field in the presence of an alternating current. The two windings of the device are wound in such a way that they oppose each other, creating an inductive voltage which cancels out any common mode interference present. The inductive voltage is then used to attenuate the signal, thus reducing the amount of noise present in the system.In summary, the ALFT-03A-7 is a type of common mode choke designed for use in high speed, precision electronics. It has a square shaped mounting bracket to keep it firmly in place and is constructed with a pair of opposed coils wound from N80 core material. It has a maximum operating temperature of 125°C and a voltage rating of 250V AC, along with a frequency range of up to 250MHz and a maximum input impedance of 160Ω. The device helps to reduce the effects of disruptive noise and helps to limit the amount of heat generated in a system by reducing the voltage and current levels of signals passing through it.
