RJR26FW203R MEPCOPAL / BOURNS Potentiometer Resistor Cermet

Review MEPCOPAL / BOURNS Trim Potentiometer Resistor Cermet. 20k Ohm

The MEPCO Pal Bourns RJR26FW203R is a high-performance potentiometer resistor manufactured by MEPCO Pal Bourns. This component is part of the CERMET series, which stands for Ceramic Metal Film, a technology known for its excellent stability and precision. The resistance value of this specific potentiometer is 20,000 ohms or 20k ohms.

This 20k ohm potentiometer features a linear taper design, which means the resistance changes linearly as the potentiometer is turned. It is constructed using a ceramic body with a metal film resistive element. The ceramic material provides excellent thermal stability, allowing the potentiometer to maintain a consistent resistance value over a wide temperature range.

The metal film resistive element ensures high precision and stability. The film is applied onto the ceramic base using a vacuum deposition process, which results in a very uniform thickness and high resistance stability. The resistance tolerance for this 20k ohm potentiometer is typically /- 5%, ensuring accurate control of the electrical resistance.

The RJR26FW203R has a wiper diameter of 6.35 millimeters and a total length of approximately 33.1 millimeters. The body of the potentiometer is sealed to protect against dust and moisture, ensuring reliable operation even in harsh environments. The termination type for this potentiometer is wire leads, with a length of approximately 6 inches (152 millimeters) each.

In summary, the MEPCO Pal Bourns RJR26FW203R is a high-precision, 20k ohm potentiometer resistor that offers excellent thermal stability, resistance stability, and reliability due to its CERMET technology construction. Its linear taper design, sealing against the elements, and wire lead termination make it a versatile and practical component for various electrical applications.

5. Operating Temperature: -40 C to 85 C

6. Packaging: 6mm diameter, 12.5mm length, and TO-5 package type

1. High resistance value suitable for various applications

2. Wide operating temperature range (-40 C to 85 C)

3. Low temperature coefficient, ensuring accurate resistance over temperature changes

4. TO-5 package type, which is compact and easy to install

5. 1 Watt power rating, suitable for moderate power applications

1. Higher cost compared to other types of resistors, such as carbon composition or metal film resistors

2. Slightly larger size compared to thin-film or thick-film resistors

3. Slightly higher tolerance and temperature coefficients compared to other high-precision resistor types

4. Requires more care during handling and installation to avoid damage to the delicate carbon film

The Mepco Pal Bourns RJR26FW203R 20k cermet potentiometer-resistor offers several advantages, including a wide operating temperature range, low temperature coefficient, and high resistance value. However, it does have some disadvantages, such as a higher cost and larger size compared to other resistor types.

If your application requires a high resistance value, and you need a component with a wide temperature range, and you're willing to pay a premium for the advantages of a cermet potentiometer-resistor, then the Mepco Pal Bourns RJR26FW203R is an excellent choice. However, if you're looking for a lower-cost, more compact, or higher-precision resistor, you may want to consider other types, such as carbon composition, metal film, thin-film, or thick-film resistors.
