Cement-coated wire wound resistors ZK

Product catalog summary
Overview: This document provides technical specifications for cement-coated wire-wound resistors with ferrules, produced by KRAH-RWI ELEKTRONISCHE BAUELEMENTE GMBH. It includes details on resistance ranges, tolerances, dissipation capacities, and dimensions.
Specifications:
  • Resistance Range: The resistors cover a range from R 47 to 330 K.
  • Resistance Tolerances: Available tolerances are K (± 10%), J (± 5%), and G (± 2%).
  • Dissipation Capacities: Varying dissipation capacities are provided at different temperatures (40°C, 70°C) and voltages (400 V to 4000 V).
  • Limiting Voltage: The resistors can handle voltages from 400 V to 4000 V.
  • Surface Temperature Limit: The maximum allowable surface temperature is 350°C.
Dimensions:
  • Resistors are available in various sizes, with dimensions specified in millimeters (e.g., ZK 13 x 55, ZK 24 x 265).
  • Alternative mounting options are available, and dimensions can be customized upon request.
Additional Features:
  • Non-inductive resistors are available, as indicated in the product description.
  • Resistors can be supplied with adjustable lugs (ZK ... V).
  • Other styles and special versions are available upon request.
Ordering Information: An example order designation is provided: 1000 pieces ZK 24 x 100 - 8 K 2 J.
