VPG FRSM Ultra-Precision SMD Resistors
Vishay Precision Group FRSM Ultra-Precision SMD Resistors use a Z1 foil wraparound SMD resistor for precision circuits. These resistors maintain the calibrated resistance over temperature, applied power, and operating life, which matters more than initial tolerance alone. The FRSM resistors offer very low typical TCR, a low power coefficient, and published load-life stability over thousands of hours help minimize resistance change after calibration. These resistors feature a 5Ω to 240kΩ resistance range, up to 800mW at +70°C, and tolerance as tight as ±0.01%. The FRSM resistors ADC/DAC scaling, voltage references and gain setting, calibration, metrology, and ATE and precision instrumentation.
