High-power ripple resistor selection criteria


Corrugated resistors It is important to note the following guidelines: Corrugated Resistors Metallized film resistors exhibit an inverse oxidation reaction at dc loads, and this repercussion can be more severe in hot and humid environments. Corrugated resistor When the resistor to accept the communication load, if the operating frequency is low, according to the winding resistors, metal oxide film resistors, metal film resistors, carbon film resistors, the composition of the film resistor and the composition of real core resistor Series selection. When operating at frequencies above tens of kHz, consider the high-frequency characteristics. In general, the corrugated resistor metal film resistors series of thin film resistor resistors are three times the drift of carbon film. Therefore, when applied to power derating, the carbon-film resistor family appears to have a lower drift-out than the metal-film resistor family. There is a fine alloy foil resistor, both metal film and winding the advantages of both resistors, the resistance is very stable, the corrugated resistor and has good frequency characteristics, when the operating frequency below 5 MHz, is basically a Pure resistor corrugated resistor, which is often used as a standard resistor.
