PE-0603PFB471ST Filters

Ferrite beads and chips are components used to reduce EMI interference and suppress noise in various electronics devices. The PE-0603PFB471ST is a ferrite bead in a 0603 SMD package. It is used for radio frequency (RF) interference suppression in the frequency range of 10 MHz to 100 MHz. The component is capable of blocking RF signals while maintaining an optimum signal path with minimal impedance.

The PE-0603PFB471ST ferrite bead consists of a core of ferrite material enclosed in a package of epoxy and lead. The component has an impedance of 4.7 µH at 10MHz, and is designed to be used at a maximum current rating of 1 Amp. It has a typical resistance of 0.2 µOhms at 10MHz and a capacitance between 0.3-0.6pF.

The ferrite material used in the PE-0603PFB471ST exhibits a high degree of magnetic permeability, which means it is able to block the flow of RF frequencies while allowing the passage of lower-frequency signals. This makes it ideal for use in radio receivers and other electronics which require low noise operation. In addition, its low impedance ensures minimal signal attenuation and minimal interference with other components in the circuit.

The PE-0603PFB471ST is primarily used to reduce EMI interference in electronic circuits. It is also used in electronic devices to protect against over-voltage transients and switching noise. The use of a ferrite bead to suppress EMI is common in automotive, computer, and audio/video electronics.

The working principle of the PE-0603PFB471ST ferrite bead is based on the fact that it is a non-linear magnetic device. As current passes through the component, an electromagnetic field is created which induces a flow of eddy currents in the ferrite material. These eddy currents in turn create their own magnetic field, which opposes the field created by the current flow. This opposition acts to dampen the current flow, suppressing high frequency EMI while allowing lower frequency signals to pass.

The PE-0603PFB471ST ferrite bead is an inexpensive, general-purpose component with a wide range of applications. It is used to reduce EMI in a variety of electronic devices, including radio receivers, MP3 players, audio amplifiers, and other audio/video equipment. In addition, its low impedance makes it suitable for use in power supplies and high-frequency electronic circuits.
