SC7, SCB Vishay Electro-Films CHIP RESISTORS Thin Film Resistors on Silicon, User Trimmable FEATURES Product may not be to scale The SC7 and SCB series resistor chips offer a combination of nichrome user trimmability as a single resistor or as a ratio trim while maintaining the excellent TCR tracking characteristics of two resistors on the same chip. The SC7 and SCBs are manufactured using Vishay ElectroFilms (EFI) sophisticated thin film equipment and manufacturing technology. The SC7 and SCBs are 100 % electrically tested and visually inspected to MIL-STD-883. * Wire bondable * Chip sizes SC7 - 0.030 inches square SCB - 0.050 inches square * Resistance range RT: 100 to 20 k for SC7 Resistance range RT: 100 to 50 k for SCB * Silicon substrate * Power: 250 or 400 mW capability * Resistor material: Nichrome * User trimmable APPLICATIONS Vishay EFI SC7 and SCB chip resistors have excellent power dissipation capability and are ideally suited for prototyping. Typical application areas are: * Couplers * Amplifiers * Filters * Oscillators * Attenuators Recommended for hermetic environments where die is not exposed to moisture TEMPERATURE COEFFICIENT OF RESISTANCE, VALUES AND TOLERANCES Tightest Standard Tolerance Available PROCESS CODE SC7 0.1 % 25 ppm/C 50 ppm/C 100 ppm/C 100 200 50 k SCB CLASS H* CLASS K* CLASS H* CLASS K* 220 224 220 224 221 225 221 225 222 226 222 226 *MIL-PRF-38534 inspection criteria RA user trimmable 50 % above RT value specified in P/N STANDARD ELECTRICAL SPECIFICATIONS PARAMETER Noise, MIL-STD-202, Method 308 Stability, 1000 h, + 125 C at Rated Power Operating Temperature Range Thermal Shock, MIL-STD-202, Method 107, Test Condition F High Temperature Exposure, + 150 C, 100 h Dielectric Voltage Breakdown Insulation Resistance Operating Voltage DC Power Rating at 70 C Derated to Zero at 150 C 5 x Rated Power Short-Time Overload, + 25 C, 5 s - 20 dB typ. 0.2 % max.
