RCK Series Vishay Foil Resistors High Precision Foil Resistor with TCR of ± 2.0 ppm/°C, Tolerance of ± 0.005 % and Load Life Stability of ± 0.005 % FEATURES INTRODUCTION Bulk Metal® Foil (BMF) technology outperforms all other resistor technologies available today for applications that require high precision and high stability. This technology has been pioneered and developed by Vishay Foil Resistors (VFR), and products based on this technology are the most suitable for a wide range of applications. BMF technology allows the production of customer-oriented products, designed to satisfy specific challenging technical requirements. The RCK series of BMF resistors offers low TCR, excellent load life stability, tight tolerance, fast response time, low current noise, low thermal EMF and low voltage coefficient, all in one resistor. The RCK series is virtually insensitive to destabillizing factors. The resistor element is a solid alloy that displays the desirable bulk properties of its parent material, thus it is inherently stable and noise free. The standard design of these resistors provides a unique combination of characteristics found in no other single resistor. • Temperature coefficient of resistance (TCR): - 55 °C to + 125 °C, 25 °C ref. - RCK0X series: ± 2 ppm/°C typical (see table 1) • Power rating: to 1 W at + 125 °C • Resistance tolerance: to ± 0.005 % (50 ppm) • Load life stability: ± 0.005 % at 70 °C, 2000 h at rated power • Resistance range: 0.5 Ω to 1 MΩ (for higher or lower values, please contact Application Engineering) • Vishay Foil resistors are not restricted to standard values; specific “as required” values can be supplied at no extra cost or delivery (e.g. 1K2345 vs. 1K) • Electrostatic discharge (ESD) at least to 25 kV • Non inductive, non capacitive design • Rise time: 1 ns effectively no ringing • Current noise: 0.010 µVRMS/V of applied voltage (< - 40 dB) • Thermal EMF: 0.05 µV/°C • Voltage coefficient: < 0.1 ppm/V • Low inductance: < 0.08 µH • Non hot-spot design • Terminal finishes available: lead (Pb)-free, tin/lead alloy • Matched sets are available on request (TCR tracking: to 0.5 ppm/°C) • Prototype quantities available in just 5 working days or sooner.

Standard Test Operations: By 100 % Inspection • Short-time overload (6.25 x rated power for 5 s) • Resistance - tolerance check • Visual and mechanical By Sample Inspection • TCR • Environmental tests per table 3 on a quarterly basis to establish performance by similarity B. Standard Test Conditions: • Lead test point: 0.5" (12.7 mm) from resistor body • Temperature: + 23 °C ± 2 °C • Relative humidity: per MIL-STD-202 IMPROVED PERFORMANCE TESTING (IPT) The preceding information is based on product directly off the production line. Improved performance (meaning increased time stability with load and other stresses) is available through factory conducted “Improved Performance Testing”. The test routine is usually tailored to the user’s stability objectives and IPT-processed resistors can exhibit improved load-life stability levels of less than 50 ppm. Various screen test routines are available and all anticipated stresses must be taken into account before settling on one specific test routine. VFR's application engineering department is prepared to discuss and recommend appropriate routines given the full spectrum of anticipated stresses and stability requirements.

The resolution limit of existing test equipment (within the measurement capability of the equipment, or “essentially zero”.) µV/°C relates to EMF due to lead temperature difference and µV/watt due to power applied to the resistor.
