? semiconductor components industries, llc, 2015 february, 2015 ? rev. p2 1 publication order number: EMI7112/d EMI7112 product preview emi filter with esd protection product description the EMI7112 is an l?c emi filter array with esd protection that integrates two pi?filters (c?l ?c) to suppress emi/rfi noise. EMI7112 includes esd protection diodes on all input/output pins, and provides a very high level of protection for sensitive electronic components against possible electrostatic discharge (esd). the esd diodes connected to the filter ports safely dissipate esd strikes of 30 kv, which is beyond the maximum requirement of the iec61000?4?2 international standard. features ? two channels of emi filtering ? 30 kv esd protection (iec 61000?4?2, contact discharge) ? 30 kv esd protection (iec 61000?4?2, air discharge) ? greater than 45 db of attenuation at 900 mhz ? these devices are pb?free and are rohs compliant applications ? mobile phones maximum ratings (t a = 25 c) rating symbol value unit esd discharge iec61000?4?2 contact discharge air discharge v pp 30 30 kv rms current per line i line 350 ma operating temperature range t j ?40 to +125 c storage temperature range t stg ?55 to +150 c lead solder temperature (10 second duration) t l 260 c stresses exceeding those listed in the maximum ratings table may damage the device. if any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. this document contains information on a product under development. on semiconductor reserves the right to change or discontinue this product without notice. marking diagram device package shipping ? ordering information www. onsemi.com EMI7112fctag wlcsp5 (pb?free) 5000/tape & ree l ?for information on tape and reel specifications, including part orientation and tape sizes, please refer to our tape and reel packaging specification brochure, brd8011/d. wlcsp5 fc suffix case 567kk block diagram a1 filter #1 a3 c1 filter #2 c3 gnd b2 gnd b2 7a = specific device code m = date code 7am
