Custom RTD elements, Power resistors as heating elements. Compensation Resistors, Metal and Thick Film networks and arrays.
These Precision Shunt Resistors are designed for systems which have a fast changing electrical load. It has a Heatsink and is encapsulated in epoxy. The substrate is Alumina for Good Heat Transfer but with Electrical Insulation. It is a Resistor formed by a NiCr Foil. (Like Nichrome).
Resistors are probably the most common and well known of all electrical components. Applying a resistor to a circuit normally requires (1) calculating the nominal values needed in the circuit application (resistance, power rating, etc.) then (2) developing acceptable tolerances for the resistor that ensure it will function properly in all extremes of the application.
Read up the “Temperature dependence and TC” – The absolute ohmic value of a resistor is temperature-dependent. Also the “Definition of terms in the specifications of Resistors.”

High Value Resistors in Thick film technology is a Specialization. Products include precision and power resistors, special Ceramic Chip Capacitors, Temperature Sensors and other High Grade Passive Electronic Components.
In the expansion of the existing types of High Value and High Voltage resistor series, SRT is presenting at electronica 2006 under the designation HVR25 a leaded resistor, which has a working voltage of 15kV at a length of only 25mm.
By means of an optimized design for high working voltages, SRT has succeeded in realizing at this length and a width of 9 mm this improved version of High Voltage resistors. Compared with the type HVR30 with 30mm length, the working voltage could be increased by 5kV and the Voltage Coefficient (VCR) reduced by about 50%.
