Huge inventory of Resistors. 1-Source Electronic Components
www.1sourcecomponents.com
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.
Action Steps
The best contacts and resources to help you get it done
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.
I recommend: Go to All Electronics for a power resistor, including flat ceramic, sand, axial or ceramic types; then order online. Get power wire wound resistors at Micro-Ohm; look at the bottom of the page to order by phone or email.
Get high voltage resistors for heavy duty applications
Applications for high voltage resistors include, among others, generators, RF amplifiers, relays and medical equipment.
I recommend: Contact direct sales USA at Caddock Electronics for various types of resistors rated up to 48 KV, or view resistors by clicking “Products” then “Precision High Voltage Resistors.” Select a product number from “Standard Part Number” with maximum operating voltages as high as 90 KV then get phone or email information at the bottom of the page. Contact ITT for precision metal oxide high voltage resistors available in several configurations.
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.
I recommend: See the prices at Action Electronic Wholesale for variable resistor potentiometers with switches, multi-turn, and PB board mount trimmer pots and online ordering. Find commercial and industrial grade electric potentiometers including single- and multi-turn rotary, linear and rocker pot at Precision Sales; click the electric potentiometer of choice for details and call to order.
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.
I recommend: Go to Allied Electronics for a wide selection of resistors with prices to order online or look at the interactive choices to find your particular type. Fill in the form at Peerless Electronic Equipment for electronic resistors, or click “Line Card” then “Resistor Products” for product categories.
Tips & Tactics
Helpful advice for making the most of this Guide
- • 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.
