Review BOURNS Resistance 250

The Bourns 3400S-1-254 is a high-performance, precision trimming potentiometer designed for applications requiring fine resistance adjustments. This component is a 3-terminal, linear, trimpot with a 1/4 watt, 250 ohm resistance value.

The 3400S series potentiometers from Bourns are known for their excellent stability and low TCR (Temperature Coefficient of Resistance). The TCR value for this specific model is rated at 250 ppm/ C, ensuring that the resistance value remains consistent even under varying temperature conditions.

The Bourns 3400S-1-254 features a non-rotary, linear design, making it an ideal choice for applications where precise, continuous resistance adjustments are necessary. The potentiometer's wiper is made of beryllium copper, which provides excellent conductivity and wear resistance. The shaft is made of a robust, insulating material, ensuring long-term durability and preventing short circuits.

This trimpot comes with a flat, knobless shaft and a clear, epoxy coating that protects the potentiometer from moisture and contaminants. The epoxy coating also helps to minimize the potentiometer's size, making it suitable for space-constrained applications.

The 3400S-1-254 is designed to meet or exceed RoHS and REACH compliance, making it an environmentally friendly component option. It can be mounted on a PCB using the provided mounting holes and is suitable for operation in temperatures ranging from -30 C to 85 C.

In summary, the Bourns 3400S-1-254 is a high-precision, linear trimming potentiometer with a 250 ohm resistance value, offering excellent stability, low TCR, and robust design suitable for various applications where fine resistance adjustments are required.

The Bourns 3400S-1-254 resistor is a popular choice for various electronic applications due to its reliable performance and precise tolerance. However, like any other electronic component, it has its advantages and disadvantages that should be considered before making a purchase.
