THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENTARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT Wirewound high Power Vitreous Resistors with Terminal Collars or BandsThe RW Wirewound Power Resistors are extremely well suited to professional applications, where high Power and excellent endurance are required. They meet all requirements of NF C 93-214 specifications and five sizes cover the Power range from 10 W to 80 W. Non inductive types are available, by using the special RWNI winding. For higher Power or extremely severe conditions of use, see the RWST F 16101, 10/1988 and 16102, 04/1992: Not applicable (our parts are made of metallic and refractory materials).
