FNR2E-0R25F1

Chassis Mount Resistors

The FNR2E-0R25F1 is a particular chassis mount resistor, designed for the purpose of providing protection to other components in the circuit. It is commonly employed as a short- or medium-term protection device to withstand transient or static overvoltage that may damage other components.

Application Field

Resistor FNR2E-0R25F1 is used in automotive, consumer, telecommunications, computing, and other industrial applications. It can provide protection in power supply circuits, radio circuits, audio systems, automotive engine systems, computer systems, consumer electronics, and industrial control systems. The resistor is especially useful for areas that require static or transient protection. In many cases, the resistance of this particular resistor may also be needed to restrict current flow, establish signal voltage levels, and provide biasing functions.

Working Principle

The FNR2E-0R25F1 resistor is a nonlinear resistive element that functions similarly to a piece of wire in that it produces a resistance that is increased or decreased by the amount of current passing through it. The resistance affects the signal levels and can limit the current flow through the circuit components. The resistor increases resistance with increasing voltage and current. This resistance is proportional to the voltage and current, allowing for precise control of the current and voltage levels in the system.

The resistor also provides transient and static protection from overvoltage and overcurrent. In the case of an overvoltage, increased resistance is provided in the form of an inner oxide layer. This layer acts as a barrier between the overvoltage and the other components in the circuit, protecting the other components from damage. In cases where an overcurrent is present, the current is limited to a maximum level to prevent damage to the components.

By using the FNR2E-0R25F1 chassis mount resistor, engineers can have confidence that their circuitry is well protected from both static and transient overvoltage. This makes the resistor an essential component in industrial, consumer, and automotive applications.
