Working Principle of H4649KBCA

The H4649KBCA is a simple, standard through hole resistor, containing a ceramic body, a resistive element, and two metal (or lead) terminals. The ceramic body is made of a variety of materials, depending on the resistance requirements and temperature-rating of the resistor, and contains a measured amount of resistive material, usually a conductive ceramic or metal alloy, depending on the desired resistance value. This resistive element is located between the two terminals.

When a voltage is applied across the two terminals, a current will pass through the resistive element, and this current will be limited by the resistance value of that element. The precise value of the resistance depends on the resistive material used in the body, as well as the size, shape, and orientation of the ceramic material.

The H4649KBCA also features a variety of safety and reliability features. It is flame-resistant, flame-retardant, and includes a silicone conformal coat which resists moisture and other environmental contaminants. It is also highly resistant to vibrations, shocks, and temperatures extremes, which makes it ideal for use in harsh environments.
