179COILS WITH TEMPERATURE COMPENSATING MEANS


DEFINITION

Classification: 336/179

(under the class definition) Inductor devices wherein the coil or winding and/or supporting structure thereof is so

constructed as to maintain the inductance of the device constant over a predetermined range of ambient temperature, or wherein the device is designed to follow a predetermined law of variation of inductance with ambient temperature.

(1) Note. The inductance of the device may be maintained constant by (1) utilizing structural components having equal compensatory temperature coefficients, or (2) utilizing winding and/or supporting structure members having constant temperature coefficients.

(2) Note. Inductor devices controlled by an external temperature sensitive element are not herein included. For such subject matter see subclass 30.
