4211R-19

Ferrite beads and chips are indispensable components in electronic devices and provide a variety of functions.One of the most important applications of ferrite beads and chips is passive radio frequency (RF) interference suppression.This article looks specifically at the 4211R-19 ferrite bead and chip along with its application field and working principle.

Overview of 4211R-19

The 4211R-19 is a low-profile ferrite chip bead with a 1900 MHz (1.9 GHz) maximum operating frequency and a 1.5 Ohm impedance at 50 MHz. It consists of two ferrite cores in a package and is used primarily for RF interference suppression.The 4211R-19 ferrite chip is rated for a max power of 1 watt and is available in 14 pin packages.When used for RF interference suppression, the 4211R-19 can be combined with coaxial cables and capacitors to provide superior signal protection.It is also suitable for use in 10base-T, 100base-T, and 1000base-T Ethernet applications.

Application Field

The 4211R-19 ferrite chips have a variety of applications in industrial, automotive, and consumer electronics.In industrial applications, it is used for noise suppression in high-frequency motors, switch mode power supplies, and LED lighting systems.In automotive applications, it is used in electronic speed controllers, sensors, and actuators.It is also used in consumer electronics such as mobile phones, wireless headsets, and wireless keyboards.

Working Principle

The 4211R-19 ferrite chip works by absorbing and dissipating RF energy.This is done by passing the signal through two ferrite cores.The cores are connected to each other and to the signal source. As the signal passes through the two cores, the energy is absorbed by the ferrite material, dissipated, and does not reach the intended source.This effectively reduces undesired interference that can arise from other signals or devices.

Conclusion

The 4211R-19 ferrite chip is an effective solution for RF interference suppression.It has a variety of applications in industrial, automotive, and consumer electronics.It works by absorbing and dissipating RF energy and is suitable for use in 10Base-T, 100Base-T, and 1000Base-T Ethernet applications. With its low profile, the 4211R-19 ferrite chip can be easily integrated into any device design for superior signal protection.
