61 general description avx miniature ac varistors are designed for use in low power ac circuit protection. mav series devices are an ideal solution to transient suppression in lc resonant circuits intended for signal & power transfer. the avx part provides low loss in the resonant circuit yet is able to clamp large amounts of transients in a bi-directional manner. the ability to handle large transients makes the mav series useful in low power ac circuit protection and the aec q200 qualification allows for use in automotive applications. low capacitance makes these parts useful also for higher dc voltage data lines and other capacitance sensitive applications. how to order mav series 002 size 001 = 0603 002 = 0405 004 = 0402 0 capacitance 0 = low w packaging d = 7" reel (1,000 pcs) r = 7" reel (4,000 pcs) t = 13" reel (10,000 pcs) w = 7" reel (10,000 pcs 0402 only) p termination p = plated sn over ni barrier miniature ac varistor C mav low power ac and low capacitance dc circuit protection features ? 110 pk-pk @ 125khz capability ? aec q200 qualified ? esd rated to 25kv (hbm esd level 6) ? emi/rfi attenuation in off state ? bi-directional protection general characteristics ? operating temperature: -55 to +125oc ? working voltage: 70vdc / 52vac ? case size: 0402, 0603, 0405 2xarray applications ? lc resonant circuits ? ac sampling circuitry ? transformer secondaries ? gfi modules ? immobilizers ? keyless entry ? data lines ? capacitance sensitive applications and more antennaguard catalog part numbers/electrical values avx part number v w (dc) v w (ac) v b v c i vc e t i p i l cap elements mav0010_p 70 52 120 15% 225 1 0.015 2 10 22pf max 1 mav0020_p 70 52 120 15% 225 1 0.020 3 10 8pf max 2 mav0040_p 70 52 120 15% 225 1 0.020 1 10 6pf max 1 v w (dc) dc working voltage [v] v w (ac) ac working voltage [v] v b breakdown voltage [v @ 1ma dc ] v c clamping voltage [v @ i vc ] i l maximum leakage current at the working voltage [a] e t transient energy rating [j, 10x100s] i p peak current rating [a, 8x10s] cap maximum capacitance @ 1mhz and 0.5v rms packaging code
