Current Sensing Bondable
Chip Resistors
FEATURES
• Low ohmic value down to 0.05 Ω
• Tolerance down to 1 %
• Stability 0.1 % < 2000 h at Pn at + 70 °C
• Low noise < 35 dB
• Low TCR 100 ppm/°C
• Wirebondable
This thin film chip resistor fits applications as force balance
scales, E beam deflection systems, switching power
supplies, etc... all rely on current sensors to feed back and
control the current.
Gold pads are compatible with thermosonic or ultrasonic
bonding of gold and aluminium wires.
