High Precision Wraparound
Thin Film Chip Resistors
FEATURES
• Load Life Stability at ± 70°C For 2000 hours:
0.1% under Pn/0.05% under Pd
• Low Temperature Coefficient down to
± 10ppm/°C
• Very Low Noise and Voltage Coefficient
• Resistance Range : 10Ω to 3MΩ depending on size
• Extended Ohmic Value Range (see table)
• Tolerances to
± 0.01%
• In Lot Tracking
≤
5ppm/°C
• Termination: Thin Film Technology
• Gold Plated or Pre-tinned Terminations over Nickel
Barrier
• Short Circuits (Jumpers) r < 50mR, I < 2A
For low noise and precision applications, superior stability,
low temperature coefficient of resistance, and low voltage
coefficient, VISHAY SFERNICE’s proven precision thin film
wraparound resistors exceed requirements
o f MIL-PRF-55342G characteristics Y (± 10ppm/°C).
