ESCC ( ) 4001/023 Qualified High Precision (5 ppm, 0.01 %),
Thin Film Chip Resistors
FEATURES
• Load life stability at 70 °C for 2000 h:
0.15 % under Pn
• Low temperature coefficient down to 5 ppm/°C
• Very low noise (< - 35 dB) and voltage coefficient
(< 0.01 ppm/V)
• Resistance range: 10 to 3 M (depending on size)
• Laser trimmed tolerances to 0.01 %
• TCR in lot tracking 5 ppm/°C
Vishay Sfernice Thin Film division holds ESCC QML
qualification (ESCC technology flow qualification).
These High-Rel. components are ideal for low noise and
precision applications, superior stability, low temperature
coefficient of resistance, and low voltage coefficient, Vishay
Sfernice’s precision thin film wraparound resistors exceed
• Termination: Thin film technology

• ESCC 4001 (generic specifications)
• ESCC 4001/023 (detailed specifications)
• ESCC qualified
requirements of MIL-PRF-55342G characteristics
( 10 ppm/°C).
Y
• SMD wraparound chip resistor
• Operating temperature range: - 65 °C to + 155 °C
• From 0402 to 2010
• Material categorization: For definitions of compliance
