Through Hole Resistors provide a range of electrical resistance in various values. The most commonly used type of resistor is the surface mount resistor. However, sometimes a through hole resistor is needed to offer increased power handling capability, better heat dissipation, or to fit in hard to reach places. The PF2205-1RF1 through hole resistor is an expansion on the popular PF2205 series of through hole resistors and utilizes internal arc suppression technology for improved reliability in electrically noisy environments.

The PF2205-1RF1 through hole resistor is a low profile, five watt voltage rule unit. It is designed to meet the requirements of a through hole resistor with additional characteristics such as increased power dissipation, improved arc suppression, and melting temperature. It is rated for use in temperatures ranging from -55°C to +175°C. The PF2205-1RF1 is designed to fit into limited areas, with dimensions of only 0.41 inches (10.46mm) by 0.27 inches (6.86mm).

The resistance ratings of the PF2205-1RF1 application range from 1Ω to 3350Ω. It is available in a variety of tolerance classes, including ±1%, ±2%, ±4%, ±5%, ±20%, and ±30%. An additional ±50% tolerance class is available for emergency cases, such as when a component with a specific resistance rating is not available in the usual range.

The PF2205-1RF1 through hole resistor is constructed with an alumina base ceramic body, which helps reduce both soldering time and thermal fatigue. The body is hermetically sealed and treated with a RoHS compliant, thermoplastic protective coating to increase reliability and reduce electrical noise. This coating improves arc suppression characteristics, which can help prevent problems associated with spikes and other electrical disturbances.

The working principle of the PF2205-1RF1 through hole resistor is operated through a series of resistive layers joined together with molten tin. This creates a single resistance path, which prevents heat buildup and improves power dissipation. This design also allows for a faster response to changing temperatures, as the internal heated air can rapidly dissipate outside the enclosure. Furthermore, the improved arc suppression technology helps prevent the resistor from shorting out and increases its lifespan.

The PF2205-1RF1 through hole resistor is an ideal choice for applications that require a high level of power dissipation, arc suppression, and reliability. Any application that can benefit from a fast, reliable, and cost-effective solution would benefit from using this resistor. The small size and lightweight design also make it suitable for a wide variety of applications. Ultimately, the PF2205-1RF1 is an excellent choice for applications where arc suppression and increased power dissipation are required.
