maruwa g eneral catalog emi filters 86 cnf31 type the cnf31 . cnh31 . cnh30 . cnh32 series is a 3-terminal emi filter for smt based on multilayer chip capacitor technology. the cnh series is suited for reducing emi noise on dc power lines. t w l 1 l 1 l 2 l ? due to its small size and low residual inductance, noise reduction is possible at higher frequencies than conventional capacito rs. ?high current rating (~2a), makes it well suited for reducing emi noise on dc power lines. ?high capacitance (0.1 f max.) enables reduction of noise over a wide frequency range. ?nickel and tin plated barrier terminations offer good solderability and resistance to soldering heat. ?rohs compliant. noise reduction for signal lines and dc lines in computers, computer peripheral equipment, digital tv, dvd recorder, cellular t el- ephone, automotive electronics, printer, fax, etc. : "t" stands for taping package and "b" stands for bulk package. equivalent circuit dimensions part number system insertion loss (reference) features applications (mm)
