Common mode chokes are electrical components used for suppressing the common-mode noises generated by electromagnetic interference (EMI). HM85-50771LFTR is one type of common mode chokes which is specifically designed for EMI protection of high frequency data lines. It combines a power inductor and thin film technology to provide the highest common mode noise suppression capability.

The application field of HM85-50771LFTR includes differential signal lines such as LAN, HDD, and LVDS and high precision signal lines such as GPS and camera modules. By reducing the noise in these signal lines, the device can ensure signal integrity, reduce the transmission loss, and enhance signal stability. In addition, as a shielding element, HM85-50771LFTR can also protect the circuit from interference between different lines.

The working principle of HM85-50771LFTR is based on the Faraday’s law of induction. As the common-mode noise of the signal line passes through the device, it induces a magnetic flux in the core, which creates a counter EMF which opposes the current flow. This EMF is the noise suppression that the device provides. The Faraday’s law of induction states that the EMF is proportional to the rate of change of magnetic flux, which means that the amount of noise suppression depends on the rate of rise of the signal current.

HM85-50771LFTR combines both high performance and small size to provide advanced EMI protection for various differential signal lines, and its various features make it a cost-effective and efficient EMI suppressor. The device has high common-mode noise suppression capability ensured by its durable power core material which allows for great thermal stability. It also has a low profile which allows it to fit in tight spaces.

Due to its combination of high performance, small size, and cost-effectiveness, HM85-50771LFTR is a superior choice for EMI protection. It can provide reliable noise suppression of high frequency data lines and protect the circuit from interference. It is an excellent choice for applications such as LAN, HDD, LVDS, GPS, and camera modules.
