Through-hole resistors are a type of electrical resistors which feature an screened, cylindrical body containing a wire or a stack of resistive wafers. The wire or stack of resistive wafers are encased in a metal-glass envelope and typically have an insulation sleeve or shield on one end. Compared to surface mount resistors which are preferred in higher-density PCBs, through-hole resistors offer the advantage of larger leads. This makes them suitable for prototyping and experimenting with circuit boards.

CPCF03330R0JE66 is a through-hole resistor from Vishay. It features a wirewound construction with an ohmic value of 3.3 Ohm at 1/4 watt, a tolerance of 5% and a dissipation coefficient of 10W. It is also protected by a fluoride-based, moisture-resistant enamel coating and the terminals measure 2mm in length.

The application field for this resistor is quite wide, ranging from automotive and industrial applications to consumer electronics. When used in automotive circuitry, it can be used as a voltage divider or as a load resistor for lighting systems, while in industrial or home automation settings, it can be used to regulate and limit the current in AC/DC power supplies or in other low-frequency circuits. Some of the common applications in consumer electronics include surge protection and variable control for current or voltage in various circuits.

In terms of working principle, like all other resistors, the CPCF03330R0JE66 works by utilizing the current-limiting properties of resistance. This means that it restricts the flow of electric current by dissipating electrical energy in the form of heat, leading to an effective reduction of the voltage or current level in a circuit. The amount of current limiting can be determined by the ohmic value of the resistor and the power dissipation is proportional to the current squared.

Overall, CPCF03330R0JE66 is a versatile through-hole resistor that can be utilized in a variety of applications, from automotive and industrial to consumer electronics. Its wide ohmic value, tolerance and power dissipation coefficient allow for a wide range of applications. It works by limiting the current flow through a circuit by dissipating electrical energy, effectively regulating the voltage or current in a circuit.
