3386P-1-102 BOURNS Trimpot Cermet Trimmer Pot Turn

Review BOURNS Qty 149 Trimpot Cermet Trimmer Pot Turn .5w 1k Ohm

The Bourns 3386P-1-102 149 TRIM-POT is a high-performance, 5-watt, 1-kilohm trimmer potentiometer designed for use in various electronic applications. This CERMET (Ceramic Metal) trimmer potentiometer is known for its exceptional stability, precision, and durability.

The 3386P-1-102 TRIM-POT features a rotary design, allowing for precise adjustments to be made with minimal effort. The trimmer's resistance value can be adjusted from a minimum of 900 ohms to a maximum of 1100 ohms, providing a fine resolution for calibrating and fine-tuning circuit settings.

This trimmer potentiometer is constructed using a CERMET element, which offers several advantages over other types of potentiometer elements. CERMET trimmer pots provide excellent temperature stability, with a coefficient of thermal resistance (TCR) of 22 ppm/ C. They also exhibit low power dissipation, making them well-suited for applications where heat generation is a concern.

The Bourns 3386P-1-102 149 TRIM-POT is a robust component, with a 10mm diameter shaft and a 6.35mm mounting hole. The trimmer potentiometer is also RoHS compliant and lead-free, ensuring that it meets the latest environmental regulations.

The trimmer potentiometer comes with a grip knob, which provides a secure and comfortable grip for users while making adjustments. It also features a detent mechanism, which allows for positive click detents at each resistance value, making it easier to accurately set and maintain desired resistance values.

In summary, the Bourns 3386P-1-102 149 TRIM-POT is a high-precision, 5-watt, 1-kilohm CERMET trimmer potentiometer designed for use in a variety of electronic applications. Its exceptional temperature stability, low power dissipation, and fine resistance adjustment make it an ideal choice for applications where precise calibration and fine-tuning are essential.

The Bourns 3386P-1-102 149 TRIMPOT CERMET TRIMMER POT WITH A TURNING RESISTANCE OF 5W-1K is a variable resistor commonly used in electronic circuits for adjusting voltage or current levels. Here are some pros and cons that might help you in deciding whether to buy this component:

1. High Precision: The Trim Pot offers a high degree of precision, making it suitable for use in applications where accurate adjustment of resistance is required.

2. Stable Resistance: The CERMET (Ceramic-Metal) composition of the Trim Pot ensures that the resistance value remains stable over a wide temperature range.

3. Compact Size: The Trim Pot has a small footprint, making it ideal for use in compact electronic circuits.

4. Easy to Use: The Trim Pot can be easily adjusted by turning the dial, allowing fine-tuning of resistance values without the need for complex tools or techniques.

1. Limited Power Handling: The Trim Pot has a maximum power handling capacity of 5 watts, making it unsuitable for applications where higher power levels are required.

2. Fragile: The Trim Pot is a delicate component and can be damaged easily if not handled with care during installation or adjustment.

3. Limited Operating Temperature Range: The Trim Pot has a relatively narrow operating temperature range, making it unsuitable for use in extreme temperature environments.

In conclusion, the Bourns 3386P-1-102 149 TRIMPOT CERMET TRIMMER POT WITH A TURNING RESISTANCE OF 5W-1K is a high-precision variable resistor that is suitable for use in applications where accurate adjustment of resistance is required, and the resistance value needs to remain stable over a wide temperature range. However, it has limited power handling capacity, is fragile, and has a narrow operating temperature range.

If you are looking for a variable resistor with a higher power handling capacity or a wider operating temperature range, you may want to consider other types of variable resistors, such as wirewound or carbon composition resistors. However, if you require the high precision and stability offered by a CERMET Trim Pot, and the operating conditions are within the specified limits, then this component could be an excellent choice for your electronic circuit design.
