    Wire Wound Ceramic Braking Resistor

    $51.54
    Ceramic braking resistor (wire wound resistor) uses high temperature resistant mullite porcelain tube as the winding base, 50W~6000W rated power for selection, optional resistance in 1Ω~3000Ω. Dielectric voltage reaches AC2.5kV/1min 50Hz. It adopts high temperature resistant, flame retardant and insulating inorganic coating to effectively protect the resistance wire from oxidation, long service life and affordable price.

    Tips: Classification and characteristics of wire wound ceramic braking resistors.

    1. Vertical corrugated wire-wound ceramic resistor: larger heat dissipation area, can withstand higher pulse voltage, short hedging time, but strong adaptability in use environment with high pulse voltage. By adopting the reverse double winding method, non-inductive winding resistance can be manufactured, and the parasitic inductance is effectively reduced.
    2. Sliding adjustable ceramic resistor: Zero to maximum resistance can be adjusted. By sliding the middle slider, an adjustable resistance is obtained to control the output of circuit current.
    3. Flat-wound ceramic resistor: High-resistance resistors, resistances up to 20000 ohms, which is suitable for high-resistance environments.
