Resistors are widely used, but different applications require different types of resistors. Do you know the differences between radial and axial resistors?

Let WEET tell you, the core difference between radial and axial resistors lies in their lead arrangement and application scenarios. 

INTRODUCTION

Resistors Types

• Through hole resistor: Leads extend from both ends of the resistor body along the central axis.

• Radial resistor: Leads protrude from the same end (or adjacent positions) of the body.

Mounting Method and Space Occupation

• Through hole resistor: Axial resistor sizes for through-hole mounting, requiring linear space reserved along the direction of the leads.

• Radial resistors: Support through-hole mounting and surface mount technology (SMD). Vertical mounting saves horizontal space, enabling a more compact layout.

Application Scenarios

• Through hole resistor: Commonly used in traditional circuits, audio equipment, and projects with fixed requirements for lead spacing.

• Radial resistors: Preferred for miniaturized devices such as printed circuit boards (PCBs) and high-density circuits.
