BLM21PG220SZ1D

Ferrite Beads and Chips, also known as ferrite cores, are used for a variety of applications ranging from basic filtering to more specialized applications such as EMI/RFI shielding. The BLM21PG220SZ1D is a ferrite bead designed for a wide variety of EMI / RFI filtering applications.

The BLM21PG220SZ1D is a ferrite bead that measures 2.2 mm in outer diameter and 1 mm in height. The bead is constructed of a material with a permiability of 22 and an inductance of 220 uH. It is rated to handle currents up to 20 amps and has a maximum operating temperature of 125 degrees Centigrade.

The primary application field of the BLM21PG220SZ1D is EMI/RFI filtering and shielding. This bead is particularly useful in cases that involve high currents, such as power supplies, and those that involve multiple circuit boards with sensitive components, such as computers. In these cases, the bead helps to shield the sensitive components from electromagnetic interference and radio frequency interference.

The working principle of the BLM21PG220SZ1D is based on the fact that a ferrite bead behaves like an inductor when placed in an electrical circuit. When a current passes through the ferrite bead, the magnetic field created by that current core acts to absorb any electromagnetic interference and radio frequency interference that is present in the circuit. This in turn helps to ensure that the components in the circuit are shielded from any potential interference, allowing them to function as intended.

In addition to EMI/RFI filtering, the BLM21PG220SZ1D can also be used in other applications. For example, it can be used as an inductor in power supply circuits, for matching impedances, or for suppressing Line Noise.

In summary, the BLM21PG220SZ1D is a ferrite bead designed for a wide variety of EMI/RFI filtering and shielding applications. Its primary application field is EMI/RFI filtering and shielding, but it can also be used in other applications such as power supply circuits, for matching impedances, or for suppressing Line Noise. The working principle of the BLM21PG220SZ1D is based on the fact that a ferrite bead behaves like an inductor when placed in an electrical circuit, and that the magnetic field created by the current core can absorb any electromagnetic interference and radio frequency interference.
