The BLM21BD102SN1D ferrite bead is a surface-mounted rectangular component with a 0402 package size and a rated operating voltage of 50 volts. Its maximum dc resistance is 1 ohms and its impedance is between 100 to 600 ohms in the frequency range of 0.05 to 2GHz. The device can operate in temperatures ranging from -55°C to 125°C and its storage temperature range is -45°C to +85°C. Its typical dissipation factor is .5 Watts, or .36 at 1GHz.
The BLM21BD102SN1D is best used for its signal conditioning capabilities in noisy and high frequency environments. The resistance and permeability of ferrite absorb unwanted signals in the frequency range desired, blocking them from interfering with normal functions. Since this component operates at very high frequency and can be connected directly to a printed circuit board, its response time is extremely fast.
The most common use of the BLM21BD102SN1D is in mobile phones. The ferrite bead is installed between the batteries and the phones digital processing components to prevent noise and signal interference. Its ability to decrease the amount of signal interference allows the phone to be more reliable. The device can also be used for the same purpose in other electronic equipment.
The BLM21BD102SN1D Ferrite Bead also has a wide variety of other applications. Its small size and low power requirements make it useful for mixed-signal high-speed printed circuit board designs, such as USB 2.0/3.0 and Mini HDMI connectors. It can also be installed in consumer electronics, automotive, and aerospace and defense systems. The component is particularly useful in harsh environments, where it can be used to protect circuits from high voltages or current variations.
The working principle of the BLM21BD102SN1D is based on the theory of inductance. The ferrite material’s high permeability allows it to absorb electromagnetic fields, while the resistive component that the device creates impedes the current in the desired frequency range. By blocking unwanted signals, the component ensures that only the desired signal passes through.
