BLM21BB750SN1D Filters

Ferrite Beads and Chips

Ferrite beads and chips are components used to reduce the amount of noise which may otherwise be produced in electronic or electrical systems. They are especially effective at preventing signals from radiating into the environment. Among the wide range of ferrite beads and chips are the BLM21BB750SN1D.

BLM21BB750SN1D Application Field

The BLM21BB750SN1D is a Chip Ferrite Bead, designed to suppress signals over the 1GHz frequency spectrum. The most common application of it is in mobile phones, to prevent the high frequency signals from radiating and causing external interference or reduce the effects of external interference. This component is also used in NAV navigation equipment, microwave devices, GPS receivers, and cellular communication equipment, where it performs a similar function.

BLM21BB750SN1D Working Principle

The BLM21BB750SN1D works by using its ferrite core material to create a magnetic field around the signal, which restricts it from propagating outside the circuit. This magnetic field is generated by the current in the signal. The amount of inductance created is much higher for higher frequency signals, so it works particularly well on higher frequency signals such as those found in mobile phones. The component also creates an impedance which is not affected by external signals, giving it excellent noise suppression qualities.

Summary

Ferrite beads and chips have many application fields, one of which is the BLM21BB750SN1D. This component is designed to suppress signals over the 1 GHz frequency spectrum, which makes it commonly used in mobile phones, GPS receivers, and NAV navigation equipment. The working principle of the BLM21BB750SN1D involves creating a magnetic field around the signal using its ferrite core material, which restricts it from propagating outside the circuit. It also creates an impedance which is not affected by external signals, allowing it to provide excellent noise suppression.
