0805USB-421MLC Description

Short technical summary and product information.

The Coilcraft 0805USB-421MLC is a surface mount common mode choke designed for common mode noise suppression in high-speed differential signal lines such as USB 2.0, IEEE1394, and LVDS. It offers a common mode impedance of 220 Ω minimum at frequencies above 3.0 GHz, with a differential mode cutoff frequency of 3.5 GHz. The component provides typical common mode attenuation of 1.1 dB at 10 MHz, 2.3 dB at 100 MHz, and 8.4 dB at 500 MHz.

 

Electrical specifications include a minimum inductance of 23 nH at 100 MHz, maximum DC resistance of 120 mOhm, and a current rating of 500 mA per winding (20°C rise from 25°C ambient). The winding-to-winding isolation voltage is 250 Vrms, hipot tested for one minute. The operating temperature range is -40°C to 85°C.

 

The choke is housed in an 0805 package (2.03mm x 1.27mm) with a maximum height of 1.65mm, featuring a horizontal, 4 PC pad configuration. It is constructed with a ferrite core and weighs approximately 14.9-15.2 mg. The component is AEC-Q200 qualified (85°C+) and halogen free. Packaging is available in 7-inch reels of 2000 parts or 13-inch reels of 7500 parts, on 8mm wide plastic tape with 4mm pocket spacing.
