The onsemi EMI2121MTTAG is a three-line common mode filter with integrated ESD protection, supplied in an 8-pin WDFN package with a flat termination style. It is rated for 100 mA per line with 8 ohm DC resistance and a 9 V voltage rating, and operates over -40°C to 85°C. The EMI2121MTTAG measures 2.2 mm x 2.0 mm x 0.8 mm, is lead-free and RoHS compliant, and is supplied on tape and reel. Note that the manufacturer has placed this part at end-of-life (EOL) status.

Common mode filters with integrated ESD protection sit directly at an external connector, attenuating common-mode noise on high-speed differential and control lines while clamping electrostatic discharge events before they reach the controller. Three-line devices in a small WDFN body are typically used on camera, display, audio, and data interfaces in handsets, tablets, cameras, and portable industrial equipment, where a discrete choke plus TVS array would not fit. Because this part is at end-of-life, buyers are usually sourcing to sustain existing builds or to cover a last-time-buy rather than starting a new design. Fusion Worldwide handles EOL and allocated parts of this type for OEM and EMS customers keeping mature products in production.
