Mica Product Overview Standard Dipped Minature Dipped High Frequency Ultra High Fq. Radial High Reliability Radial Tape & Reel Mica Chips 3

What is Mica? 3 Minerals consisting of hydrous slilcates of aluminum or potassium that crystallize in forms that allow perfect cleveage (very thin layers) 3 Mica capacitors are normally made from muscovite mica - potassium aluminum silicate [KAl 2 Si 3 O 10(OH)2] 4

Why Choose Mica? 3 Temperature stability 4 -55°C to +125 °C standard 4 -55 °C to + 150 °C on certain product 3 High frequency up to 1 GHz 3 Tight tolerance ± 0. 5 p. F 3 High d. V/dt to 275, 000 V/ms 4 Great for snubber applications 5
