Ferrite Beads and Chips

A ferrite bead or ferrite chip is a passive electronic component used to suppress high frequency noise in electronic circuits. They can be categorized as commutating (capacitor-input or choke-input) or non-commutating (non-inductive or high-frequency noise absorber).

The HR2220V801R-00 model is an example of a ferrite chip. It is a high-screening, surface-mountable chip ferrite bead that operates in the frequency range of 0.16~2GHz, with a maximum impedance of 0.3 Ohms. It features good insertion loss characteristics and low frequency resistance and inductance. The chip is constructed from NiZn ferrite material and offers a maximum current max of 5A with a rated DC resistance of 168mOhms. It is suitable for a wide range of applications which require high frequency noise suppression, such as automotive, data communications, consumer electronics and power management.

Working Principle

A ferrite chip works by exploiting its intrinsic magnetic properties. It essentially acts as a low-pass filter, letting lower frequencies pass through but blocking higher ones. The ferrite bead is composed of ferrite cores consisting of nickel, zinc, iron and other materials. The ferrite cores contain molecules that are arranged in a way to form a highly conductive path for low-frequency signals, but a barrier for higher frequency noise. In other words, the ferrite cores act as an impedance “barrier” for higher frequencies while the lower frequencies are allowed to flow through. This makes it an ideal component for noise reduction in electrical circuits.

The HR2220V801R-00 chip is specially designed to provide excellent noise suppression in a wide range of frequency bands. It offers excellent insertion loss characteristics, low frequency resistance and low inductance. It also features a high screening efficiency of more than 60dB, making it an ideal choice for applications that require high frequency noise suppression.

Applications

The HR2220V801R-00 chip is primarily used in automotive, data communications, consumer electronics and power management applications. To enhance system reliability while reducing system noise and interference, the chip can be used in the power and ground of the system. It is particularly useful in noise reduction in mobile phone applications. In addition, the chip can be used to filter out noise generated by car alarms, CD players, GPS systems, LED displays, and other automotive electronic components. Other applications where the HR2220V801R-00 chip can be used include mobile phone chargers, battery chargers, LCD panels, data transfer cables, digital audio systems, and defibrillators.

The HR2220V801R-00 chip is a small, durable, high-performance component that offers excellent noise suppression in a wide range of frequency bands. Its small size and high screening efficiency makes it an ideal choice for a variety of noise reduction applications. Its nickel-zinc ferrite core makes it highly resistant to temperature changes and other environmental factors. It is a reliable and cost-effective solution for reducing noise in a wide range of electronic circuits.
