High Precision Wraparound
Thin Film Chip Resistors
FEATURES
• Load life stability at 70 °C for 2000 h:
0.1 % under Pn/0.05 % under Pd
• Low temperature coefficient down to 5 ppm/°C
(- 25 °C; + 85 °C)
• Very low noise < 35 dB and voltage coefficient
< 0.01 ppm/V
Pb-free
Available
RoHS*
COMPLIANT
• Resistance range: 10 Ω to 3 MΩ depending on size
• Extended ohmic value range (see table)
• Tolerances to 0.01 %
• In lot tracking ≤ 5 ppm/°C
• Termination: thin film technology
• Gold plated or pre-tinned terminations over nickel barrier
• Short circuits (jumpers) r < 50 mR, I < 2 A
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 of
MIL-PRF-55342G characteristics Y 10 ppm/°C (- 55 °C;
+ 155 °C) down to 5 ppm/°C (- 25 °C; + 85 °C).
