Riedon - High Precision Resistors

Here are some documents that will build your awareness on how Resistors work and their Thermal behavior. These are from a firm called Riedon who design manufacture custom resistors and special resistors used in tight design requirements.

Riedon's Technical Information

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."
