Through-Hole Resistors

Engineered to reduce electrical current flow

We offer a wide variety of through-hole resistors that cover most technologies and mounting styles, including a range of products that go up to 40W in a pluggable style. Our products are rated at 3W and above, providing power at a minimal size. Explore our portfolio of resistors, which includes Citec, Holsworthy, Neohm, and CGS resistors.

A through-hole resistor is a fixed resistor that has long, pliable leads that can be stuck into a breadboard, or hand- or wave-soldered into a printed circuit board (PCB). Also known as a leaded resistor, a through-hole resistor is used to reduce the flow of electrical current within a circuit.


A through-hole resistor comes in three variations: axial, which has leads at either end; radial, which has leads pointing downward; and pluggable, which has terminals plugged into the PCB. A carbon film axial resistor is the most common through-hole resistor. 


While some through-hole resistors are more useful in breadboarding, prototyping, or other applications that avoid soldering, many through-hole resistors are automatically inserted into PCBs. The components are supplied on bandolier tape and the equipment cuts and forms the leads before inserting them. The whole board is then sent through a wave solder machine to solder the leads in place.
