Through Hole Resistors

Through hole resistors are passive components used to provide electrical resistance in circuits. One of the most widely utilized types of through-hole resistor is the PNP7WVFT-91-0R2, a potentiometer manufactured by TT Electronics. This two-terminal resistor offers high power handling capabilities, excellent linearity, and soft-touch rotational tracking for adjustments, making it an excellent choice for many high-power applications.

Application Field

The PNP7WVFT-91-0R2 is commonly used in a variety of industrial complex systems for power rating levels ranging from 3W to 30W. It is particularly well-suited for high-precision industrial applications, where accuracy and stability are required, such as the motor control systems used in automotive, aerospace, and robotics, as well as for medical and military applications.

Working Principle and Design

At the core of the PNP7WVFT-91-0R2 is a patented design that utilizes two internal metal or carbon resistors positioned at a fixed distance along the length of the resistor. When the knob is adjusted, the relative position of the two resistors changes, increasing or decreasing the resistance between the terminals accordingly. The internal resistors are designed for superior performance, providing excellent linearity and accurate tracking of the position of the knob with respect to resistance values. The resistor is available in standard resistance values of 0.25 Ohms to 1 KOhm.The PNP7WVFT-91-0R2 is available in many different designs, from standard 3W to 30W power rating levels and 10-Shaft Tangent Control Knobs for accurate adjustment between resistance values. The high-power design features a robust and durable housing, ensuring the product is reliable and suitable for harsh environments. For applications requiring extra environmental protection, the PNP7WVFT-91-0R2 is also available with a dust-proof or waterproof housing.

Discrete Mounting

The PNP7WVFT-91-0R2 resistor can be mounted in a variety of ways, including through hole mount and surface mount for easy integration into existing systems. For through-hole mounting, the resistor must be soldered into a printed circuit board (PCB). The high-power design also allows for mounting directly onto a chassis or heat sink. To ensure the best performance and structural integrity, the resistor should be mounted with appropriate spacing between the board and the chassis or heat sink.

Conclusion

The PNP7WVFT-91-0R2 is an excellent choice for a wide range of high-precision applications requiring stable and precise resistance with low power levels. Its patented design, high power handling capability, and multiple mounting options make it a versatile and reliable choice for industrial systems.
