Panasonic MA2C029T Silicon epitaxial planar type variable resistor Datasheet

Varistors
MA2C029
Series
Silicon epitaxial planar type variable resistor
For temperature and reduced voltage compensation
Unit : mm
φ 0.45 max.
• 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
