Review OHMITE Potentiometer Mod. Pn 2.5k Ohms /-10% Nos

The Ohmite 47495 potentiometer is a high-performance adjustable resistor designed for various applications, particularly in power electronics and industrial control systems. This specific model is a 2.5k ohm version with a taper of 0.707A, also known as a "V" or "linear taper."

The resistance range of this potentiometer is from 0 to 2500 ohms, making it suitable for adjusting voltages or currents within a broad spectrum. The 0.707A taper means that the resistance changes at a consistent rate, providing a more linear relationship between the potentiometer's rotation and the output.

This Ohmite potentiometer comes with a precision carbon composition element that ensures a stable, reliable, and accurate resistance value. It is rated for a maximum power dissipation of 12.5 watts, enabling it to handle moderate power loads without overheating.

The resistance tolerance for this particular model is 10%, ensuring that the actual resistance value is within 10% of the stated value. It has a total resistance of 4.74 k , as denoted by the part number.

The Ohmite 47495 potentiometer features a robust design with a 3/4-inch (19 mm) length and 1/2-inch (12.7 mm) diameter. It is designed to operate in temperatures ranging from -30 C to 85 C, making it suitable for use in a wide range of industrial environments.

This potentiometer has a rotary actuator with a 1-inch (25.4 mm) shaft length, making it easy to integrate into various systems. It is available in a non-encapsulated format, which allows for easy customization and modification.

The Ohmite 47495 potentiometer is a versatile and reliable component that offers excellent performance and precision for a broad range of industrial and power electronics applications. Its high power rating, accurate resistance value, and stable taper make it a trusted choice for engineers and technicians looking for a high-quality adjustable resistor.

The Ohmite 47495 potentiometer (model 2.5k, 0.707A /-10, 12.5W, NOS) is a linear voltage divider component commonly used in various electronic applications. Before deciding to purchase this potentiometer, it's essential to consider its advantages and disadvantages.

1. Wide Operating Voltage Range: This potentiometer can operate with a voltage range of -10V to 10V, making it suitable for various applications.

2. High Power Rating: With a power rating of 12.5W, this potentiometer can handle high power loads, making it ideal for applications requiring significant power.

3. Precise Resistance Value: The 2.5k ohm resistance value provides accurate voltage division and can be used to create precise voltage levels in circuits.

4. Carbon Composition: Carbon composition potentiometers are known for their durability and stability over a wide temperature range.

1. Temperature Coefficient: Carbon composition potentiometers have a relatively high temperature coefficient, meaning their resistance value can change with temperature. This may lead to inaccuracies in voltage division.

2. Low Precision: Carbon composition potentiometers are not as precise as other types such as film or wirewound potentiometers, making them less suitable for applications requiring high accuracy.

3. Non-Linear: Carbon composition potentiometers are non-linear components, meaning their resistance value does not change linearly with the rotation angle. This can result in inaccuracies in voltage division at the extremes of the potentiometer's range.

In conclusion, the Ohmite 47495 potentiometer offers several advantages, including a wide operating voltage range, high power rating, and durability. However, its disadvantages, such as a high temperature coefficient, low precision, and non-linearity, may make it less suitable for applications requiring high accuracy or precise voltage division.

Recommendation: If you require high precision or a stable voltage division, consider using a film or wirewound potentiometer instead. However, if you need a potentiometer that can handle high power loads and operate over a wide voltage range, the Ohmite 47495 potentiometer may be an excellent choice for your application.
