marking code 0402- no mark due to size. 0603 and 0805 series - because of their small size, these parts are marked with a single dot. the inductance value represented by the dot is shown on the data sheet for each series. 1008 and 1206 series - these parts are marked with three color dots. the table below shows the significance of each color. dots 1 and 2 indicate the inductance in nanohenries dot 3 is a multiplier showing the number of added zeroes 0 = black 5 = green 1 = brown 6 = blue 2 = red 7 = violet 3 = orange 8 = gray 4 = yellow 9 = white examples: gray red black = 82 nh brown red brown = 120 nh yellow violet red = 4700 nh 2 american technical ceramics www.atceramics.com atc north america 631-622-4700 ? sales@atceramics.com atc europe +46 8 6800410 ? sales@atceramics-europe.com atc asia 631-622-4700 ? sales@atceramics-asia.com atc 0402 wl series wire wound chip inductors the above part number refers to an atc 0402 wl wire wound chip inductor, 10 nh, k (?0%) tolerance, in tape and reel packaging. tighter tolerances are available. consult factory. srf rdc 900 mhz 1.7 ghz inductance tolerance q (mhz) (ohms) idc l q l q (nh) (%) min. typ. max.
