These tantalum chips combine excellent stability 0.07 %
(2000 h, rated power at + 70 °C) with great power handling
capacity. Two bonding pads per termination allow greater
flexibility in hybrid layout design.
FEATURES
•Center tap feature
•Resistor material: Self-passivating
Tantalum nitride
•Silicon substrate for good power dissipation
•Wirebondable
•Compliant to RoHS directive 2002/95/EC
