Introduction

Common mode chokes (CMC) are electronic components that are designed to help reduce the amount of electrical interference or noise on an electrical line. Common mode chokes are most commonly used with electronic equipment, specifically, in applications where there is high RF or EMF levels. Common mode chokes are one of the most important components in electrical systems as they essentially “choke” or reduce the amount of electromagnetic energy (EME) that can pass through an electrical device. The Motorola TCE1608-900-4P is a good example of a common mode choke that has specific application fields and working principle.

How CMC Works?

The way CMCs work is by using a magnetic core which is wrapped with multiple windings of wire. Each winding of the wire is aimed at creating an inductive field. These inductive fields then interact with the incoming electromagnetic energy and partially absorb it. This absorption of EM energy stops it from entering the electrical system, thus reducing the amount of interference and improving the performance of the equipment or system.

TCE1608-900-4P application field and working principle

The TCE1608-900-4P is a high-performance common mode choke which is designed specifically for automotive applications. It has a coil size of 14.2 mm x 9.2 mm and has a rated operating temperature of -40 to +105°C. The TCE1608-900-4P is rated for a current of 10A, with a nominal inductance of 15.4mH, a resistance of 1.21Ohm, and a saturation current of 16A. The working principle of the TCE1608-900-4P is very similar to that of a standard common mode choke. It uses an inductive magnetic core which is wrapped with layers of wire. When an AC current is applied, the inductor creates an electromagnetic field, which interacts with the AC current and reduces the amount of interference or EME that passes through it. The TCE1608-900-4P also has the added benefit of having a relatively low saturation current, making it ideal for applications where high-intensity current surges are expected. The primary application fields of the TCE1608-900-4P include automotive and industrial systems. The choke is commonly used in automotive electronics such as anti-lock braking systems, electric power steering systems, powertrain control systems, and infotainment systems. It is also used in industrial applications such as motor control systems and power supplies.

Conclusion

The Motorola TCE1608-900-4P is a common mode choke specifically designed for automotive and industrial applications. It uses an inductive magnetic core which is wrapped with a combination of windings to reduce the amount of interference or EME that passes through it. The TCE1608-900-4P is rated for a current of 10A and a saturation current of 16A, making it ideal for applications where high current surges are expected. By using a common mode choke, engineers can create more reliable and efficient electrical systems that are less susceptible to interference and noise.
