Vishay Dale
Thick Film Surface Mount Chip Resistors,
Current Sensor, 4-Terminal
FEATURES
• 4-Terminal design allows extremely low
resistance value (0.01
)
with tight tolerance
(1 %)
• High power to foot print size ratio
• Suitable for current sensing in power supplies
and other applications
• Metal glaze on high quality ceramic
• Protective overglaze
• Lead (Pb)-free solder contacts on Ni barrier layer
• Material categorization: for definitions of compliance
