COLOR BANDS. The resistors are permanently color banded for resistance value and tolerance in accordance with EIA specifications. Ambient Temperature (°C) 2. HELIXING. The units are helixed to a predetermined base to final value ratio to obtain the best TCR, noise and stability characteristics. High-Frequency Characteristics (Typical) 3. FILM. Carbon-film resistors have a homogeneous film of pure carbon deposited by a pyrolitic process at carefully controlled temperatures. 100Ω 1.0 Ratio Rf/RDC 1KΩ 10KΩ 0.8 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. 0.6 0.4 100KΩ 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. 0.2 0 0.1 1 10 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. 100 Frequency (MHz) Current Noise (Typical) HOW TO ORDER: RN 1/4 GP-55 0.3 RN 1/2 GP-60 0.1 0.01 -40 0.003 -50 1K 10K 55 100K Nominal Resistance (ohms) 1001 F Size TCR Resistance Value 3 digit range and 1 digit multiplier Tolerance F = 1%, D = .5%, C = .25%, B = .1% 2 100 IRC Type -20 -30 100 GP -10 0.03 10 Sample Part No.: 0 (db) Ratio Rf/RDC 1.0 Packaging: Bulk or Tape and Reel WIREWOUND AND FILM TECHNOLOGIES DIVISION 736 Greenway Road • Boone, North Carolina 28607-1860 • Tel: 828-264-8861 • Fax: 828-264-8866 • www.irctt.com
