NTC Beta Temperature

Beta-model resistance to temp.

Inputs

NTC data

Measured thermistor resistance in ohms.

Nominal resistance, usually at 25 C.

Use the part-number Beta, not a generic 3950.

Reference temperature of R0, usually 25.

Verify

Check before relying.

Beta is a two-point promise.

  • R0 at 25 C from the part number
  • Beta valid inside its stated range
  • Table beats beta at the edges
