Ceramic Resistors

Ceramic resistors

Ceramic resistors are widely used and typically consist of resistive wire wound around a ceramic core. They are available in various sizes and shapes, such as rods, discs, sleeves, and rings, to accommodate different applications and customer requirements. Electrical contact is established by depositing metals like brass, aluminum, or copper onto the resistors. This can be done through molded-on contacts, capped leads, or secured metal caps.

Ceramic resistor cores serve multiple purposes, including reducing current flow, adjusting signal levels (to divide voltage), and terminating transmission lines. While these applications are common, ceramic resistors offer versatility beyond these functions. They provide reliable performance in a wide range of electronic circuits and systems.
