DR331-474BE is a surface mount data line choke designed for EMI suppression in data and signal lines. It features a bifilar winding configuration with an inductance of 470.0 ± 25% µH at 100 kHz, 0.1 Vrms, and a leakage inductance of 0.28 µH. The device has a maximum DC winding resistance of 0.28 O, a rated current of 0.5 A, and operates over a wide frequency range exceeding 1000 MHz. With an open construction design that is more economical than the DR332 Series, it operates reliably across temperatures from -40°C to +135°C and is RoHS compliant. This choke is ideal for high-speed data applications, telecommunications equipment, and signal integrity protection where low leakage inductance and broad frequency response are essential.
