4-channel emi filter with integrated esd protection revision february 21, 2014 1 / 3 @ socay electronics co., ltd. 2014 specifications are subject to change without notice. please refer to www.socay.com for current information. EM2374K socay electronics co., ltd. www.socay.com lwson-08 the EM2374K is a four-channel (c-r-c) pi-style emi filter array with integrated esd protection. its typical component values of r=100 and c=8.5pf deliver a cutoff frequency. this performance makes the part ideal for parallel interfaces with data rates up to 70 mbps in applications where wireless interference must be minimized. the specified attenuation range is very effective in minimizing interference from 2g/3g, gps, bluetooth ? and wlan signals. the EM2374K is available in the low-profile 8-lead 1.7mm x1.35 mm lwson-08 surface mount package. u filter performance: 30db minimum attenuation 1.8ghz to 2.5ghz u bidirectional emi/rfi filter with integrated tvs for esd protection u tvs working voltage: 5v u resistor: 100 ? 20% u typical capacitance: 20pf (vr = 0v) u protection and filtering for four lines u solid-state technology u rohs compliant u iec61000-4-2 (esd) 15kv (air), 8kv (contact) u iec61000-4-4 (eft) 40a (5/50ns) u emi filtering for lcd and camera data lines u emi filtering and protection for i/o ports and keypads u nominal dimensions: 1.7 x 1.35 x 0.50 mm u molding compound flammability rating : ul 94v-0 u quantity per reel : 3,000pcs u reel size : 7 inch u lead finish : lead free symbol parameter value units t l lead soldering temperature 260 (10sec) o c t j junction temperature 125 o c t stg storage temperature range -55 to +150 o c t op operating temperature range -55 to +85 o c iec61000-4-2 (esd) air discharge 15 kv contact discharge 8 iec61000-4-4 (eft) 40 a mechanical characteristics (@ 25 un less otherwise specified) d escription feature functional diagram applications m echanical characteristics
