EMI2121MTTAG Description

Short technical summary and product information.

The EMI2121MTTAG is an integrated common mode filter with ESD protection designed for high-speed serial digital interfaces such as USB 2.0. It provides EMI filtering for one differential data line pair and ESD protection for one data pair plus a supply input.

 

It has a maximum current rating of 100mA, a typical DC resistance of 8 Ohms, and a cutoff frequency greater than 2 GHz. Common mode stop band attenuation is greater than 25 dB at 700 MHz and greater than 30 dB at 800 MHz. ESD protection meets IEC61000-4-2 Level 4 with ±12 kV contact discharge.

 

The device is supplied in a RoHS-compliant, halogen-free, Pb-free WDFN-8 package with exposed pad, measuring 2.20mm x 2.00mm x 0.80mm. It is surface mountable and supplied in tape and reel packaging with 3000 pieces per reel.

 

Typical applications include USB 2.0 and other high-speed differential data lines in mobile phones, digital still cameras, and automotive interfaces. The SZ prefix variant is available for automotive applications requiring AEC-Q101 qualification and PPAP capability.
