Construction
The metal film is deposited onto a high purity ceramic rod. End caps are force fitted and termination wires are welded
to the end caps. Finally, a cement protection is applied to the resistor body prior to marking with indelible ink. The
cement protection is applied in a manner that leaves the terminations completely clear. This permits a well-defined
body length (clean lead to clean lead dimension L).

Solvent Resistance
The body protection and marking are resistant to all normal industrial cleaning solvents suitable for printed circuits.
