The above values are nominal. Thermal data are compiled from a variety of sources and are provided for convenience only. Hysteresis is a complex property for which no hard data exists. Generally, however, hysteresis decreases with increasing mechanical Q.

Polarization:	OD positive, OD negative on special request.
Standard Tolerances:	OD: +/- .002" Length: +/- .003" Wall Thickness: +/- .001", except +/- .002" for 0.125" OD tubes longer than 0.5" Eccentricity: .002" max, except .004" max for 0.125" OD tubes longer than 0.5"
Example Dimensions:	OD: 0.125", 0.25", 0.375", 0.5", 0.75", or 1.00" Length: up to 1.25" for 0.125" OD, up to 3.0" for all other ODs Wall Thickness: 0.01" to 0.023" for 0.125" OD, 0.01 to 0.04" for all other ODs
Electrode Types:	Nickel, Gold, Copper, or Silver (Silver not available for tubes with IDs < 0.20")
Electrode Options:	Single or double wrap tabs Axial segmenting (such as four 90° quadrants on the OD & ID) Circumferential Bands Electrode removal at the tube ends Lead attachment

Other wall thicknesses, lengths, diameters, tolerances, and electrodes on request. Drawings or sketches are strongly urged.

Note:

All values are nominal: actual production values may vary up to 20%.
