PL8202T

Common Mode Chokes are widely used in numerous applications, from network components to electronic test equipment. One example is the PL8202T, a product line designed and manufactured by Pulse Electronics. It is designed to suppress common mode noise on digital, power, and telecommunication lines.

PL8202T devices are small and robust, making them suitable for space-constrained applications. They have a nominal inductance range of 0.5 to 30µH, and are available in sizes from 0.200” to 0.500”. The surface mount packages can accommodate high current ratings, up to 3.00A, and operate at temperatures from -55°C to +125°C.

The PL8202T works by providing a high impedance to ground for both common and differential noise. This high impedance prevents common mode noise from entering the protected device; in parallel, the Electrical Fast Transient/Surge (EFT/Surge) immunity of equipment and systems is improved. The PL8202T’s ferrite construction makes it well suited for both low and high frequency applications.

The PL8202T leverages Pulse Electronics’ patented core geometry and advanced manufacturing process to achieve a low core loss and a wide operational bandwidth. The choke construction and inductance are optimized for suppressed insertion loss on high speed telecommunication networks. The mathematically simulated response is tested and verified in an extensive system test to ensure products’ performance.

Common Mode Chokes, such as the PL8202T, are suitable for a wide range of applications such as:

• Power line filters
• Power supply input/output
• Communication lines
• Automotive and circuit design
• Meters and displays
• Data acquisition systems
• Broadband transmission
• Mobile and wireless applications
• Medical devices

The working principle behind the PL8202T Common Mode Choke is quite simple. It is designed to couple the transmitted signal while blocking common mode noise; preventing it from entering the device. The choke has been optimized to offer a low insertion loss coupled with a wide bandwidth.

The controlled impedance ensures that the choke is able to provide the expected suppression while maintaining signal integrity and emission control. This makes it ideal for reducing EMI as well as protecting sensitive electronics from damage. The construction of the device also makes it highly reliable when used on the hostile environments and harsh conditions.

In summary, the PL8202T Common Mode Choke is a reliable, robust and compact product, perfect for suppressing common mode noise in numerous applications. Its patented core geometry and advanced manufacturing process enables high power handling while preserving signal quality. Furthermore, it provides superior electrical performance in a wide range of environmental conditions, making it suitable for a variety of applications.
