Common Mode Chokes are widely used in a variety of electronic products, including DR331-474BE. This type of choke is used to reduce electromagnetic interference (EMI) and improve signal integrity. The DR331-474BE is a common mode choke designed to reduce common mode noise in high frequency signal lines.

The DR331-474BE has a choke type of B and an inductance of 4.7 milli-Henry. It has a rated current of 0.005A (5mA) and standard temperature range of -40°C to +105°C. The DR331-474BE includes two axial leads and a dielectric withstanding voltage of 500V DC. It has a maximum operating frequency of 100MHz and a maximum operating temperature of 125°C.

The DR331-474BE is designed to block common mode noise while simultaneously allowing differential mode noise to pass through. This is done using two inductors wound in opposite directions around a ferrite core, which acts as a transformer to couple the two inductance loads. The DR331-474BE also has an internal shield, which helps to further reduce common mode noise.

The DR331-474BE is suitable for use in a variety of signal applications, including video, audio, and digital data cable lines. It is especially useful for long cable runs, as it is able to reduce EMI that could otherwise cause signal degradation. It is also compatible with a variety of operating voltages, making it suitable for use in a variety of power supplies.

In summary, the DR331-474BE is a common mode choke designed to reduce common mode noise in high frequency signal lines while allowing differential mode noise to pass through. It is suitable for use in a variety of signal applications, including video, audio, and digital data cable lines. The DR331-474BE has two inductors wound in opposite directions around a ferrite core and an internal shield to reduce EMI, making it ideal for long cable runs.
