| 200 Series Vishay Foil Resistors Bulk Metal(R) Foil Technology Conformally Coated Precision Current Sensing Resistors with TCR of 5 ppm/C and values down to 5 m FEATURES * Temperature Coefficient of Resistance (TCR): 5 ppm/C (0 to 60 C) (see table 1) Pb-free Available * Tolerance: to 0.02 % (see table 1) * Power Rating: 2 W at 25 C RoHS* COMPLIANT * Load Life Stability: 0.005 % at 25 C, 2000 hours at Rated Power * Resistance Range: 0.005 to 500 * Electrostatic Discharge (ESD) above 25 000 V * Non Inductive, Non Capacitive Design * Rise Time: 1.0 ns without ringing * Current Noise: < - 40 dB * Thermal EMF: 0.05 V/C typical * Voltage Coefficient: < 0.1 ppm/V * Non Inductive: 0.08 H * Non Hot Spot Design * Terminal Finishes Available: Lead (Pb)-free Tin/Lead Alloy * Any value available within resistance range (e.g. 1K234) * Prototype samples available from 48 hours. For more information, please contact foil@vishay.com * For better performances, please see VCS300 series datasheet Any value available within resistance range The VCS200 Series offers resistance values as low as 5 m and TCR's as low as 5 ppm/C with excellent long term stability. The resistors are conformally coated. The 4 terminal current sensing resistors can sustain 2 W continuously without an appreciable change in resistance (0.5 % maximum). The typical 50 % derating of the power specification associated with other technologies is not necessary. Our Application Engineering Department is available to advise and to make recommendations.
