The SDCW2012-2-901TF from Sunlord is a 2-line wire-wound chip common-mode choke from the SDCW series. It is designed to suppress high-frequency common-mode noise on signal lines while maintaining compact dimensions and a low-profile construction for space-constrained electronic designs.
The device provides 900Ω ±25% common-mode impedance at 100MHz, with a maximum DC resistance of 0.80Ω. Maximum rated current is 150mA, rated DC voltage is 50V, and minimum insulation resistance is 10MΩ.
Sunlord specifies the SDCW series for high-frequency common-mode noise suppression. Typical applications include USB 2.0 interfaces in PCs and peripheral equipment, small digital AV equipment, LVDS lines in notebook PCs and LCDs, and audio signal lines.
The SDCW2012-2-901TF uses a compact 2012 / 0805 SMD package measuring approximately 2.0 ±0.2 × 1.2 ±0.2 × 1.2 ±0.2mm. It features two signal lines and four terminals and operates across a -40°C to +85°C temperature range. The T code specifies tape-and-reel packaging.
