DQRDQR / DDR Series Ceramic Tube Wirewound Resistors
Ceramic Tube Wirewound Resistors
DQR/DDR series — power wirewound resistors on ceramic core with vitreous enamel or cement coating. Power 25–2000 W, resistance 0.1 Ω…50 kΩ, operating temperature up to 300 °C. Constantan/nichrome winding, non-inductive versions for pulse loads. Variants: wall-mount, clamps, terminal blocks, with thermal cutoff. Applications: VFD braking circuits, ballast resistors, voltage dividers, surge dampers in traction and industrial drives.
