MA2B027 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 IR
• Large power dissipation
• Wide forward voltage VF range
I Absolute Maximum Ratings Ta = 25°C
φ 0.56 max.
