The DR331-104AE is a surface mount data line choke designed for EMI suppression in data and signal lines. It features a sector winding configuration with an inductance of 100.0 ± 25% µH at 100 kHz (0.1 Vrms), a leakage inductance of 0.85 µH, and a maximum DC winding resistance of 0.10 O. The device is rated for a maximum current of 0.5 A and operates across a wide frequency range exceeding 1000 MHz, with an operating temperature range of -40°C to +135°C. The open construction design provides a more economical solution compared to the DR332 Series, while maintaining RoHS compliance and featuring ferrite core construction with enameled copper wire (Class F) and Cu/Ni/Sn terminals. This choke is ideal for applications requiring effective EMI filtering in high-speed data transmission and signal integrity applications.
