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

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.
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.
Flat-wound ceramic resistor: High-resistance resistors, resistances up to 20000 ohms, which is suitable for high-resistance environments.
