Through Hole Resistors

Resistors are the most basic passive components used in electronics for controlling or limiting the flow of electrical current. Through-hole resistors are physically inserted and soldered into the circuit board, hence the “through-hole” designation. Through-hole resistors are available in a variety of physical sizes and packages. These resistors generally offer larger maximum power dissipation ratings than their surface-mount counterparts.

RN55E2940DB14 Application Field and Working Principle

The RN55E2940DB14 is a precision through-hole resistor utilized for various electronic applications, mainly in the industries of consumer electronics, automotive, and medical. Its strong resistance and accurate resistance values make it suitable for critical circuit design requirements. The RN55E2940DB14 has a power rating of 2W and features metal-film construction with tolerance values down to as low as 0.1%. It has a flat-end chassis package for easy installation, and is available in a wide range of resistance values.

The RN55E2940DB14 is a four-terminal surface-mount resistor featuring a metal-film resistor construction. It utilizes precise metallurgically formed film layers arranged over specially plated leads and sputtered with a tantalum-aluminum alloy. This leads to very low inductance and excellent temperature stability. The thick-film resistive network is encased in an electrostatically-adhered polyimide coat.

The RN55E2940DB14 utilizes a nickel-pedestal construction with solid-lead supports in order to provide better lead-to-resistor adherence. This combination allows it to easily support higher power ratings in larger devices without additional support. The resistor’s four leads permit tighter control over the actual device resistance, especially for components with large tolerance values.

The circuit on which the RN55E2940DB14 is installed will determine the direction of current flow through it. Generally, the resistor will resist the flow of current in one direction, or the other, depending upon the type of network being used; however, for some circuits, the resistor will simply allow the current to flow inonly one direction.

In order to ensure that the RN55E2940DB14 operates properly, the leads should be secured mechanically, usually by means of adhesive, and solder should be applied to the leads from one side of the resistor to the conductive track on the other side. It is important to not exceed the resistor’s power rating, and to pay special attention to the temperature rating of the resistor; when placed in a circuit, carefully monitor the resistor\'s behavior and adjust the circuit design as necessary.

The RN55E2940DB14 is an ideal choice for applications requiring highly precise resistors that can handle large thermal loads and tight tolerances. Its excellent temperature stability makes it well-suited for automotive, medical, and other high-reliability applications. Of course, the user should always ensure that the device used is compatible with the application, and that it meets all the specifications necessary for a successful installation.
