The RWR89S1871FRS70 is a through hole resistor capable of handling up to 1W of power. It is used in both consumer and industrial applications, including automotive, medical, consumer electronics, and lighting. It is often used in power supplies, electronic circuits, and PCBs. Due to its high resistance, it can be used in areas where low current draw is required.

The RWR89S1871FRS70 has a wide resistance range of 1K to 250K ohms, making it suitable for a variety of applications. It can be used in low voltage and low current circuits, or high voltage and high current circuits. It is also ideal for temperature control, noise suppression, voltage regulation, power degradation, and impedance matching.

Working Principle

The working principle of the RWR89S1871FRS70 is based on Ohm’s Law. This law states that the voltage across a resistor is proportional to the current flowing through it. The resistance of the RWR89S1871FRS70 is fixed and will not change with changes in temperature or voltage. This makes it ideal for applications where a constant voltage or temperature is required.

The resistance of the RWR89S1871FRS70 is determined by the material it is made from. The RWR89S1871FRS70 is made from carbon film, and is coated with epoxy for increased dielectric strength. The carbon film determines the resistance of the resistor, and the epoxy coating increases its robustness and durability.

In addition to having a fixed resistance, the RWR89S1871FRS70 also has a tolerance of ±5%, which means that the resistance of the resistor can vary by up to 5% from its rated resistance. This tolerance makes it suitable for applications where the exact resistance of the resistor is not crucial.

The RWR89S1871FRS70 is a versatile and reliable through hole resistor. It has a wide resistance range and can be used in both consumer and industrial applications. Its fixed resistance and tolerance make it suitable for a variety of applications requiring reliable and accurate results. It is a cost-effective and high-quality solution for power supplies, electronic circuits, and PCBs.
