Ferrite Beads and Chips play a key role in many industries, from applications as varied as radio and telecommunications, automotive, and the aerospace industries. Ferrite Beads and Chips are designed to provide protection in the form of magnetic filtering, reducing electromagnetic interference (EMI). The BLM18AG331SN1D is a ferrite bead made by Murata for use in situations where EMI protection is needed.

The aim of the BLM18AG331SN1D is to reduce unwanted levels of Conducted Emissions and Susceptibility (CEM/CIS) which can cause disruption in high-frequency applications. This type of redundant filtering can be particularly beneficial in products that use extended parts of the RF spectrum, for which components like the BLM18AG331SN1D are designed to offer increased EMI/RFI immunity.

The BLM18AG331SN1D is an integrated ferrite trap designed for use at frequencies between 10MHz and 6GHz, offering low insertion loss of 0.2dB at 1GHz. The BLM18AG331SN1D is designed for surface-mount applications and is round, with a height of just 1.9 millimeters. It is available with 0402 and 0603 footprints, and is lead free, RoHS compliant.

The BLM18AG331SN1D operates on a simple principle. The alternating current (AC) that passes through the component creates a magnetic field that is used to filter out unwanted signals. The resulting filtered output will be void of any EMI, thereby ensuring reliability and performance for the system.

The BLM18AG331SN1D is most commonly used in automotive, aerospace, and telecom applications, where high levels of EMI can cause significant disruption or even catastrophic failure. It is also used in medical, military, and wireless applications, where the limited size and low insertion loss makes it ideal for use in these applications.

The BLM18AG331SN1D is available in a range of package sizes, so that it can be used in any application, regardless of space. It requires minimal assembly and has a high temperature range, making it an ideal choice for many applications.

In conclusion, the BLM18AG331SN1D is a ferrite bead available from Murata, designed for use in a range of high-frequency applications. With a wide temperature range and low insertion loss, it’s the perfect choice for applications where EMI protection is required.
