THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENTARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT Leaded Wirewound Precision ResistorsFEATURES High power dissipation in small volume Ideal for pulse application TCR 100 ppm/K Maximum permissible hot spot temperature is 275 C Lead (Pb)-free Tolerance 1 % Material categorization: for definitions of compliance please see resistor element is a resistive wire which is wound in a single layer on a ceramic rod.

2 Metal caps are pressed over the ends of the rod. The ends of the resistance wire and the leads are connected to the caps by welding. Tinned copper-clad iron leads with poor heat conductivity are employed permitting the use of relatively short leads to obtain stable mounting without overheating the solder joint. The resistor is coated with a green silicon cement which is not resistant to aggressive fluxes. The coating is non-inflammable, will not drip even at high overloads and is resistant to most commonly used cleaning solvents, in accordance with IEC 60 For Pulse Diagrams see series ( )(1)PAC02 WSZ: P25 C = W(2)Resistance value to be selected for 1 % tolerance from E24 and E96 STANDARD ELECTRICAL SPECIFICATIONSMODELPOWER RATINGP25 RANGE (2) TOLERANCE % to (1) to to to to to 12K1P x RP x RP x RP x RP x RP x Draloric Revision: 14-Mar-172 Document Number.
