Metal oxide film resistors have no residual inductance in contrast to normal wirewound resistors. Therefore, metal oxide film resistors are essential in all cases where pulse speed is important, such as in the high-frequency range. The designs offered by us have a permanent load capacity of four or ten watts, but they can be loaded much higher in the pulse range.
High-load resistors are used in crossovers for level adjustment of individual loudspeakers and in oscillating circuits or equalizer networks. In principle, they convert unwanted or excess electrical energy into heat. An important parameter is therefore the load capacity, expressed in watts.
In addition to the load capacity, the residual inductance is also important in the high-frequency range. The simple cement resistors consist of an insulator into which a wire winding is inserted. This coil behaves like a coil for very high frequencies and blocks it. For this reason, we recommend to use our metal oxide resistors in the high frequency range, since there is no coil. Instead, a conductive metal oxide layer is applied to a carrier body. This design is practically free of induction.
