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.
