DR331-113BE 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 11.0 µH (±25%) at 100 kHz, 0.1 Vrms, and a leakage inductance of 0.05 µH. The device has a maximum DC winding resistance of 0.12 O and supports a rated current of 0.5 A, with a wide frequency range exceeding 1000 MHz. Operating over a temperature range of -40°C to +135°C with a maximum temperature rise of 30°C at rated current, this RoHS-compliant component is ideal for high-speed data transmission applications requiring effective common-mode noise filtering and signal integrity protection.
