A through-hole component package featuring a cylindrical body with a single wire extending straight out from each end along the center axis. This layout allows the part to lie flat against a printed circuit board or span across a gap. While surface mount devices dominate newer designs, these packages remain standard for high-power resistors, large diodes, and parts built for hand soldering or breadboard prototyping.
Grab an axial lead resistor and bend the legs at a right angle so it drops perfectly into the breadboard holes.
When bending the wires for circuit board insertion, leave a small gap near the body to avoid cracking the ceramic or glass casing.
