1. COLOR BANDS.
The resistors are permanently color banded for resistance value and tolerance in accordance with EIA specifications.
2. HELIXING.
The units are helixed to a predetermined base to final value ratio to obtain the best TCR, noise and stability characteristics.
3. FILM.
Carbon-film resistors have a homogeneous film of pure carbon deposited by a pyrolitic process at carefully controlled
temperatures.
4. SUBSTRATES.
The substrates are of a proprietary non alkaline ceramic, prepared and processed under exacting conditions to guarantee the
utmost in uniformity and surface characteristics.
5. INSULATION.
The resistors are coated with multiple layers of a baked-on fire-retardant synthetic resin which provides the units with a high
degree of mechanical and electrical protection in the most adverse operating conditions.
6. TERMINATIONS.
Positive contact is provided to the resistance element by precision-made end caps. The lead wires are attached by using
proprietary welding techniques.
