CIC10J800NC

Ferrite beads and chips are lesser-known electronic components, but they are very important when it comes to preventing signal interference and electrical current/voltage overshoots. The CIC10J800NC is a component in the ferrite beads and chips family that’s specifically designed to resolve that issue. Let’s take a closer look at its application field and working principle.

Applications

The CIC10J800NC is designed to deal with EMI/RFI (electromagnetic interference and radio-frequency interference) sources, which are products of electrical equipment. In a nutshell, EMI/RFI sources become radiosignals that travel across the power lines and disrupt the normal operation of other electronic units. The CIC10J800NC works to eliminate that disruption so the whole system can function smoothly as a single unit.

The CIC10J800NC is one of the most popular ferrite beads among TV, computer motherboards, power adaptors, speakers and other audio devices, telephones, and handheld radios. It provides crucial protection to most sensitive electronic components that are usually found in commercial products.

The CIC10J800NC could also be found in medical equipment, especially in electronic equipment designed for hospital use. High-end devices like EKG machines, automated operating room equipment, and ultrasound imaging all employ the CIC10J800NC for EMI/RFI suppression.

Working Principle

The CIC10J800NC is based on the principle of electromagnetic interference elimination. Its key component is a ferrite, a tyoe of permanently magnetic ceramic material, which serves as an electronic filter. When an EMI signal enters the circuit, the ferrite can block (or attenuate) the signal, reducing its potential to cause any disruption to the devices in the system. It works in conjunction with capacitors and other materials to provide optimum EMI/RFI attenuation.

The CIC10J800NC has three basic components. In its input side, there’s a surface mount inductor that is designed to provide EMI suppression. It contains an inductor that is electromagnetically coupled to the ferrite bead, which serves as the filter and is able to block the incoming EMI signal. The capacitance network is placed after the filter, with the output side connecting to the output component.

The CIC10J800NC works on the principle of attenuation. As it receives an EMI signal, the ferrite bead filters out the signal and impedes its propagation. The capacitance network serves as a shunt that diffuses the energy in the EMI signal and directs it away from the input side of the circuit. As a result, the EMI signal is attenuated and its power is greatly reduced.

The CIC10J800NC may look like a very simple component, but it could be quite effective in dealing with EMI/RFI signals. With its reliable performance and affordability, the CIC10J800NC makes a great choice for many types of electronic equipment. When you use it alongside other components, you can create an effective EMI/RFI suppression system for your electronic devices.
