TEMPERATURE COEFFICIENT CODE MATCHED SETS AND NETWORKS RCDs experience in matching resistors for sets and networks can result in an economical solution for many circuits. Cost sav- ings up to 50% can be achieved by allowing relatively loose abso- jute tolerances but tight matching requirements by pair or set. Resistance matching is available to 0.01% and T.C. tracking to + 1PPM/C. RCD Components, Inc., 520 East Industrial Park Dr., Manchester, NH USA 03109 Fax: (603) 669-5455 Tel: (603) 669-0054
