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.
