6639S-301-103 BOURNS Wirewound Precision Potentiometer

Review BOURNS 2pcs Wirewound Precision Potentiometer Ohms

The Bourns 6639S-301-103 and 6639S-1-103 are high-precision, 10,000-ohm (10k) wirewound potentiometers manufactured by Bourns, Inc. These potentiometers are designed for applications that require a high degree of accuracy and stability in voltage division.

The 6639S-301-103 is a three-terminal potentiometer with a linear taper. The total resistance between the outer terminals is 10,000 ohms. The resistance between the center terminal and the wiper is variable, and it ranges from 0 ohms to 10,000 ohms as the wiper is rotated from the minimum to the maximum position. The wirewound construction of the potentiometer provides excellent temperature stability and low TCR (Temperature Coefficient of Resistance).

The 6639S-1-103 is a similar potentiometer, but it features a log taper. This means that the resistance between the center terminal and the wiper changes logarithmically as the wiper is rotated. Log taper potentiometers are often used in applications where a non-linear voltage division is required, such as in audio amplifiers.

Both potentiometers have a maximum wiper load of 250mA and a maximum operating temperature of 85 C. They are RoHS compliant and have a low power consumption, making them suitable for use in a variety of electronic applications.

The Bourns 6639S-301-103 and 6639S-1-103 potentiometers are known for their high accuracy and reliability. They are ideal for use in precision voltage dividers, instrumentation, and control systems where a stable and accurate voltage division is essential. With their excellent temperature stability, low TCR, and high power handling capacity, these potentiometers offer superior performance compared to other types of potentiometers.

In summary, the Bourns 6639S-301-103 and 6639S-1-103 are high-precision, 10,000-ohm wirewound potentiometers designed for applications that require accurate and stable voltage division. They are available in linear and log taper configurations and offer excellent temperature stability, low TCR, and high power handling capacity.

The Bourns 6639S-301-103 and 6639S-1-103 are 10k 10-turn wirewound precision potentiometers. These components are commonly used for voltage division and resistance adjustment applications in various electronic circuits. Let's discuss the pros and cons of buying these potentiometers.

1. Precision: These potentiometers are designed for high precision applications. Their 10-turn design allows for fine adjustments, making them suitable for applications where a high degree of accuracy is required.

2. Stability: Wirewound potentiometers are known for their stability over temperature and time. They have a low coefficient of thermal resistance (TCR) and exhibit minimal drift, making them ideal for applications where the resistance value needs to remain constant over a wide temperature range.

3. Linearity: The Bourns 6639S series potentiometers offer excellent linearity, with a maximum error of 0.1% over the entire temperature range. This makes them suitable for applications where a linear voltage or resistance characteristic is essential.

1. Cost: Compared to other types of potentiometers, such as linear or logarithmic, wirewound potentiometers tend to be more expensive. The precision and stability they offer come at a higher cost.

2. Size: The 10-turn design of these potentiometers makes them larger than other types with fewer turns. This can be a disadvantage in applications where space is limited.

3. Fragility: The fine winding of the wire in wirewound potentiometers makes them more fragile than other types. They need to be handled carefully to avoid damaging the winding, which can lead to resistance changes and inaccuracies.

The Bourns 6639S-301-103 and 6639S-1-103 wirewound precision potentiometers offer excellent precision, stability, and linearity, making them suitable for high-accuracy applications where temperature stability and fine adjustments are essential. However, they come at a higher cost and are larger in size than other types of potentiometers. If the application allows for it, the benefits of these potentiometers outweigh the drawbacks.

If you require a high degree of precision, stability, and linearity in your application, and have the space and budget for it, the Bourns 6639S-301-103 and 6639S-1-103 wirewound precision potentiometers are excellent choices. If space or cost is a concern, or if the application doesn't require the same level of precision, you may want to consider other types of potentiometers, such as linear or logarithmic.
