Current Sensing Resistors
NCLS Series
Metal Foil on Ceramic Current Sensing Resistors
NCLS series is ideal for use in high density low voltage high current circuits;
including DC-DC, POL, voltage regulators and power converter applications.
RoHS and REACH compliant, NCLS series is supplied on tape and reel
packaging, for automated pick and placement and are compatible with PbFree reflow soldering.
Typical unit pricing ranges from $0.03 to $0.06 USD each, when purchased in
production volumes
Features:
• Small 0603, 0805 & 1206 sizes
• Low Profile; 0.60  0.90mm Height
• Lower surface temperature
• High pulsed power capability (No trimming performed)
• Typically lower cost than metal strip type
•-55°C  +155°C operating temp range (power derated above +70°C).
• 0.25W 1W rating (Current rating; 3.5A 12.9A)
• Stable TCR: 100PPM/°C
• Resistance range: 5mΩ ~ 40mΩ
• Precision ±1%, ±2%, ±5% tolerances (F, G, J tolerances)
Circuit Applications:
• Current Sensing
• Load Balancing
• Power Management
• Point of Load Regulators
• DC-DC Convertors
• Op Amps & Amplifiers
• Fuse Monitoring
• Supply Voltage Monitoring
End-Product Applications:
•Power Supplies
•Commercial
•Industrial
•Telecomm
•Green Power
•Test & Instrumentation
