MA2C029 Datasheet, PDF (1/2 Pages) Panasonic Semiconductor – Silicon epitaxial planar type variable resistor

Varistors
MA2C029 Series
Silicon epitaxial planar type variable resistor
For temperature and reduced voltage compensation
I Features
• 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 I_R
• Large power dissipation
• Wide forward voltage V_F range
I Absolute Maximum Ratings T_a = 25°C
φ 0.45 max.
