the cnx41 . cng41 series is a 3-terminal smt emi filter based on multilayer chip capacitor technology. ? due to its small size and low residual inductance, it performs noise reduction at higher frequencies than conventional capacito rs. ?the cnx . cng series high current rating (~6a) makes it well suited for reducing emi noise on dc power lines. ?the cnx series high capacitance (~1.5 f) enables reduction of noise over a wide frequency range. ?high current priority and high frequency characteristic priority can be used properly in the cng series. ?nickel and tin plated barrier terminations offer good solderability and resistance to soldering heat. ?rohs compliant. features noise control for . the digital video signal lines in tv,vtr,dvd . computers and computer peripheral equipment . automotive electronics . dc lines in printer ,fax,etc. part number system applications : "t" stands for taping package and "b" stands for bulk package. part number list ?specifications equivalent circuit dimensions type lw t l 1 cnx41 cng41 1.6 0.3 4.5 0.3 1.0 0.3 2.8 0.2 0.3 0.2 4.5 0.15 1.6 0.15 1.0 0.15 2.0 l 2 0.1 0.2 0.4 0.2 0.1 (mm) l w t l 1 l 2 cng l w cnx t l 2 l 1 a (c) b (d) c,d (a,b) a (c) b (d) c,d (a,b) a b c d d b a c insertion loss (reference) cnx41 type cng41 type 0 10 20 30 40 50 60 70 80 90 11 0 100 1000 10000 0.01 0.1 (a-b) (c-d) cnx 41 f t 155 m z series capacitance capacitance tolerance s : 50, 20% z : 80, 20% packing form t : taping b : bulk termination m : ni-barrier termination style 41:4.5 1.6 (l) (w) temperature characteristics f : 30,?0% r : 15% insertion loss (db) frequency (mhz) cnx41r184s m cnx41r474s m cnx41f105z m cnx41f155z m cng41r184s m 50v dc 25v dc 50v dc 25v dc 50v dc 500m min. 1,000m min. 1,000m min. 0.04 max. 0.015 max. 0.01 max. ?5~+ 85 c ?5~+125 c ?5~+125 c +50,?0% +80,?0% +50,?0% 0.18 f 0.47 f 1.0 f 1.5 f 0.18 f 3a dc 6a dc 6a dc(a-b) 2a dc(c-d) 4a dc 0.025 max. part number capacitance capacitance tolerance rated voltage rated current ir dc resistance temp. range 0 10 20 30 40 50 60 70 80 90 100 11 0 100 1000 10000 frequency (mhz) insertion loss (db) 0.01 0.1 cnx41f155z cnx41f105z cnx41r184s cnx41r474s
