Inner view of Non-inductive Ceramic Resistors

[Kiriakos GR]

In modern electronics they are fewer chances one repair man to recognize a part by simple eye inspection as we did one decade back.

Back then anything white and square and externally ceramic, this was described as ceramic-housed / flame-retardant / Wire-wound resistor.

In modern pulsing power supply there is no room any more for Wire-wound resistors, mostly because due product design ( a large coil ) their use causing issues due their  inductance.
(the property of an electric conductor or circuit that causes an electromotive force to be generated by a change in the current flowing.)

New solution this is Non-inductive Ceramic Resistors, and picture bellow this is a very good example.
