Resources for Resistors

Electronic resistors restrict voltage flowing through a circuit and while doing so protect against excess voltage beyond the circuit's rating. Voltage and current values determine the resistors rating. Ohm’s law plays a critical function in the composition of the resistor.

Two main types of resistors include fixed and variable, within which many shapes, sizes, compositions and ratings exist. Fixed resistors generally contain two wires while variable (potentiometer) typically contain a rod for turning that adjusts the electronic variable required, like changing the volume on your radio. When buying electronic resistors consider the following:

1. Save time viewing inventories by knowing the required dimensions and specs of your electronic resistor.

2. Consider your inventory needs for discounts with larger orders.

3. Buy from an electronic resistor supplier or distributor with good customer relations access.

Find power resistors with your specifications

Power resistors come in fixed and surfaced mounted components with a low to high range of ohms and watts.

Get high voltage resistors for heavy duty applications

Applications for high voltage resistors include, among others, generators, RF amplifiers, relays and medical equipment.

Find variable resistors with tolerance ranges up to 1 megohm

These small electrical components maintain an industry within themselves, filling the needs for commercial and industrial applications, research and a host of electronic devices.

Deal with reputable electronic resistor suppliers and distributors

Fast delivery from in-stock inventory with competitive prices makes these companies worthwhile to check out. One company was founded in 1928 and the other in 1932.

• Body colored resistance standards indicate important features. For instance, a blue or white resistor means non-flammable and/or fusible. Never replace a non-flammable resistor with a flammable one. Some geographic locations use a composite green to indicate non-flammable.
