Common Mode Chokes are a type of electrical component used to block unwanted noise from flowing through power lines and enable the data rate of the line to remain constant. The PA2757NL is a type of Common Mode Choke that is designed to provide heavy-duty operation with minimal design complexity. This device is built with advanced semiconductor processes, making it reliable in harsh industrial environments where voltage fluctuation and signal interference are commonplace. It comprises two power inductors, each with simple filter windings, connected electrically in series with one another. These inductors help suppress disturbances on the line due to the common mode currents flowing through the core. The device is especially suitable for use in automation equipment and control systems that require reliable power performance. The PA2757NL is capable of providing a wide range of common mode filtering characteristics, with a frequency response reaching up to 40 kHz. It also features a high EMI attenuation of 11 dB, making it suitable for critical applications like medical devices where stringent EMI requirements must be met. The device has a wide operating temperature range, from -40°C to +105°C, with an operating voltage of up to 50V. Its low profile design further allows for easy integration into printed circuit boards (PCBs). Its robust construction means it can withstand shock and vibration, as well as being able to withstand exposure to most chemicals, making it suitable for highly corrosive environments. The PA2757NL\'s working principle can be understood as follows: when an alternating current (AC) flows through two inductors connected in series, the induced magnetic fields between them create a voltage in opposition to the current. This voltage helps to reduce any noise flowing in the line and stabilizes it.In conclusion, the PA2757NL is a reliable and effective Common Mode Choke designed with advanced semiconductor processes and capable of performing reliably in harsh industrial environments. It features a wide frequency response with high EMI attenuation and a wide operating temperature range, making it highly suitable for applications like medical devices that require high levels of reliability and power performance.
