Construction
A high quality ceramic substrate is assembled with
interference fit end caps to which are welded the element
winding and termination wires. The protection is then applied
to the body, providing an effective seal which is impervious to
moisture, shock, vibration, fungus and salt spray.
Terminations
Material
Solder coated copper.
Strength
The terminations meet the requirements of
IEC 68.2.21.
Solderability
The terminations meet the requirements of
IEC 115-1, Clause 4.17.3.2.
