Common Mode Chokes (CMC) are designed to reject unwanted electromagnetic interference (EMI) from a power source, particularly in electronic circuits. Common Mode Chokes are used in a variety of applications where high currents, high frequencies, and low losses are required. The most common applications for Common Mode Chokes are in the power supply industry where high currents are being handled, and in electronic communications such as video and audio equipment.The CAV-0.5-27 is a type of Common Mode Choke designed specifically for use in high current applications. The key features of the CAV-0.5-27 are its high power ratings, high current-handling capacity, and ultra-low insertion loss. The CAV-0.5-27 is designed using an integrated core coupled with a dust-proof cover, making it an ideal solution for busy power supply systems.The CAV-0.5-27\'s construction involves three high frequency plates wound on top of each other and encapsulated in an enclosing case. This construction maximizes the plate area and increases the efficiency of the choke. As a result, the CAV-0.5-27 is able to reject common mode interference over a wide frequency range, from very low frequencies up to 27 MHz.The CAV-0.5-27 comes equipped with a built in Thermal Protection circuit which prevents the choke from burning out due to excessive current or temperature. The thermal protection circuit is triggered when the choke temperature rises above a certain level. When this happens, the Thermal Protection circuit shuts off the power to the choke and trips an alarm to warn the overall system that the hot choke needs to be replaced.The CAV-0.5-27 is a highly efficient Common Mode Choke that operates on the principle of inductive reactance. Inductors and coils act as a form of impedance to alternating current, meaning that current is opposed and therefore limited. As the CAV-0.5-27 contains three sets of wound plates, the inductive reactance is increased, thus allowing the choke to reject higher frequency interference. The increased resistance also has the effect of preventing unwanted harmonics from entering the electrical system.The CAV-0.5-27 is an extremely versatile device that can operate in a variety of applications. Common uses of the CAV-0.5-27 include power supply units, audio/visual equipment, surveillance systems, communication devices and servers. The wide frequency range and robust construction make the CAV-0.5-27 perfect for applications where high levels of EMI protection are required.In summary, the CAV-0.5-27 is a highly efficient and reliable Common Mode Choke designed for use in high current applications. The choke is constructed with three sets of wound plates, giving it increased inductive reactance to reject higher frequency interference. The built-in Thermal Protection circuit ensures the safety of the choke, while its wide frequency range allows it to be used in a range of applications. With its excellent performance and reliability, the CAV-0.5-27 is a great choice for any application that requires high levels of EMI protection.
