| Varistors MA2C029 I Features Series Unit : mm 0.45 max. COLORED BAND INDICATES CATHODE 1 0.2 max. 13 min. Silicon epitaxial planar type variable resistor For temperature and reduced voltage compensation * High reliability achieved through combination of a planar type chip and glass sealing structure * Easy mounting because of employing DO-35 (DHD) envelope * Extremely small reverse current IR * Large power dissipation * Wide forward voltage VF range I Absolute Maximum Ratings Ta = 25C 0.2 max.
