800 series - rc networks ecl terminator circuits specifications are subject to change without notice. customers should verify actual device performance in their specific applications. general description digital systems incorporating emitter coupled logic (ecl) or other ultra-high switching speed logic families will require signal termination to prevent transmis- sion line effects such as reflections and ringing due to fast transition times. bourns 800 series resistor capacitor net- works are ideal for termination of high speed transmission lines. each network is composed of resistors for parallel termination and bypass capacitor(s) for cross talk noise reduction. the 5 conformal coated sip circuit varia- tions offered are as follows. electrical characteristics resistance tolerance......................? % resistance power.......................0.1 watt capacitance tolerance .................?0 % capacitor dielectric type..................x7r capacitance voltage rating .......50 volts physical characteristics flammability .........conforms to ul94v-0 leadframe ...................copper (olin 194) body material...............epoxy/anhydride (conformal material) custom resistance range ...........................10 ohms to 50k ohms custom capacitance range ................................39pf to 100,000pf npo and z5u dielectrics available on a custom basis. a maximum pin #1 ref. medium profile high profile a maximum pin #1 ref. 8.89 (.350) max. 3.43 + .38/ - .25 (.135 + .015/ - .010) 1.24 (.049) max. both ends .508 .050 (.020 .002) typ. 2.54 .07 (.100 .003*) typ. non-accum. 2.49 (.098) max. .254 .050 (.010 .002) typ. governing dimensions are metric. dimensions in parentheses are inches and are approximate. *terminal centerline to centerline measurements made at point of emergence of the lead from the body. 6.35 (.250) max. 3.43 + .38/ - .25 (.135 + .015/ - .010) 1.24 (.049) max. both ends .508 .050 (.020 .002) typ. 2.54 .07 (.100 .003*) typ. non-accum. 3.81 (.150) max. .254 .050 (.010 .002) typ. part number 4608m-801 500/103 yyww circuit resistance code pin one indicator manufacturer's trademark date code 801 and 802 represents total content. layout may vary. part number 4610h-805 500/103 yyww circuit resistance code pin one indicator manufacturer's trademark date code 803 and 805 represents total content. layout may vary. part number 4612m-804 500 yyww circuit resistance code pin one indicator manufacturer's trademark date code 804 represents total content. layout may vary. typical part marking product dimensions features optimize data transmission in ecl systems through proper termination between drivers and receivers minimize overshoot, undershoot, and ringing while increasing noise immunity provide decoupling capacitors rohs compliant* minimize space and routing problems, and reduce manufacturing cost per installed resistive function increase board yields and reliability by reducing component count for standard values used in capacitors, inductors, and resistors, click here. for information on ecl terminators, download bourns?ecl terminator application note. *rohs compliant *rohs directive 2002/95/ec jan 27 2003 including annex
