TII 3-Electrode Miniature Gas Tubes

71 Series - Heavy Duty with Radial Leads & 72 Series without Leads


DESCRIPTION

REA Accepted Per PE-80

The TII 71 three-electrode gas tube is designed for use in telecommunications circuits, signal circuits and control circuits. This surge arrester also lends itself to general purpose usage in the arresting of electrical surges and transients. The TII 71 is suitable for printed circuit board use as well as special socket applications. Leads tin plated for good solderability.
