Application:
- Measuring instruments
- Regulation equipment
Design:
- The base material is a special NiCr alloy, with a very small temperature coefficient and very good stability, deposited on substrate – glass-ceramic Sitall or Al2O3.
- The following processes are used during production: - Vacuum sputtering - Photo-lithography - Laser trimming
- The range of rated values of resistance 0,5 W to 10 MW.
- Permitted deviation ±0.01 to 0.5%, according to the customer’s requirements.
- Long-term stability <0.05%; typically 0.02%.
- Thermal coefficient ±5, 10, 15, 25, 50 ppm/°C.
- TKR concurrence in a single circuit <1 ppm/°C/cm.
- Thermal range -55°C to +125°C. · Outlets SIL Comatel, DIL Comatel, DIL (SMD), spacing 2.54 mm.
- Surface protection silicon rubber or epoxy resin (fluidisation).
Advantages:
- Very low temperature coefficient, within a single circuit excellent concurrence of the temperature coefficient of individual resistors.
- Perfect long-term stability, within the scope of a single circuit excellent concurrence of individual resistor stabilities.
Design possibilities:
- Separate resistors
- Resistor networks - Multiple="Multiple" resistors - Voltage separators - Current separators - Special wiring according to the customer’s requirements
- Damping cells
