Common Mode Chokes

Common mode chokes are passive electronic components used in AC power and signal circuits to reduce common mode noise, radio frequency interference (RFI) and electromagnetic interference (EMI). Common mode chokes are often found at the inputs and outputs of equipment, on individual wires, and inside equipment housings. They are used in a variety of applications, including low voltage and higher voltage electrical systems. Common mode chokes can provide circuit protection and improved system performance.

The TLF24HB8221R0K1 is a high performance, low cost, quenchproof common mode choke manufactured by Magnetic Components Inc. The TLF24HB8221R0K1 is designed to operate within a wide temperature range of -40°C to +150°C. It provides up to 6A DC current and has a linear inductance from 0.79mH to 1.67mH with a delta IL from 0.1mH @ 25A. The device offers frequency range characteristics of 10MHz to 2GHz.

The applications for TLF24HB8221R0K1 include power and signal line electromagnetic interference (EMI) suppression, high frequency EMI filter for input and output lines, telecommunications, CVSD circuits, and power circuits to reduce common mode noise. It is particularly effective at suppressing common-mode currents in portable electronic device applications such as radios, walkie-talkies, and miniature communication systems.

The TLF24HB8221R0K1 is designed to operate based on two primary principles. The first is the principle of electromagnetic induction. Electromagnetic induction occurs when a varying voltage or current induces a respective change in the inductance of a coil. This change in inductance creates a flow of current in the coil and generates a counter electromotive force (EMF) to the imposed voltage or current. The second principle at work is that of impedance matching. When signals of differing frequencies pass through a component, each is presented with an impedance that matches its own electrical characteristics. This matching of impedances helps suppress common mode noise and signal crossover.

The TLF24HB8221R0K1 has several applications due to its ability to provide circuit protection and improved performance. It is used in a variety of different low voltage and higher voltage systems, from radio equipment to automotive systems. It is particularly effective at suppressing common-mode currents in portable electronics such as radios, cell phones, walkie-talkies, and miniature communication systems. It is a great solution for power and signal line electromagnetic interference (EMI) suppression, high frequency EMI filter for input and output lines, telecommunications, CVSD circuits, and power circuits.

Overall, the TLF24HB8221R0K1 common mode choke is an effective way to reduce common mode noise, RFI, and EMI. Its wide temperature range, linear inductance, and low cost make it an attractive option for a variety of applications. The two primary principles it operates on are those of electromagnetic induction and impedance matching, which work together to provide circuit protection and improved system performance.
