Product Description
Murata DLW31S Surface Mount Common Mode Choke is a high-performance, small-sized SMD component designed to suppress electromagnetic interference in differential signal lines. It features a 1206 footprint with dimensions of 3.2 x 1.6 x 1.9 mm and tight inductance tolerance of ±25 %, making it ideal for precise filtering applications.
This choke supports a maximum DC current of 370 mA with a maximum DC resistance of 300 mΩ, guaranteeing efficient performance with minimal power losses. The wirewound construction and tin plating termination ensure reliability and solderability for automated PCB assembly.
The DLW31S series excels in high-frequency noise suppression, notably in USB and LVDS lines, due to its high common mode impedance (approximately 550 ohm at 100 MHz typical) and high coupling coefficient (0.98 minimum), which prevents signal distortion in high-speed data transmission.
Operating in a temperature range from -40°C to 85°C and RoHS-compliant, this component suits industrial, laboratory, consumer electronics, and communications applications. Its compact size supports dense PCB layouts in digital AV equipment, PCs, and peripheral devices.
Compact 1206 SMD package for space-saving PCB designs. Wirewound construction for enhanced noise suppression. High common mode impedance reduces EMI effectively. Suitable for USB and LVDS differential signal line applications.
Wide operating temperature range supports various environments. RoHS compliant for environmental safety. Reliable solder termination with tin plating.
