( Brand: Bourns ), ( Model: 139-2-30000 )
The Bourns 1954 NOS NA5-1554-2 is a high-quality, vintage linear potentiometer that is sure to be a valuable addition to any electronic project or repair. This 1/4 watt, 10K ohm potentiometer features a smooth, precise 270 degree rotation, making it ideal for applications requiring fine adjustments.
The NA5-1554-2 is a 139-2-30000 model, which is a part of Bourns' extensive line of linear and rotary potentiometers. It is constructed with a carbon composition resistive element, ensuring reliable and consistent performance over time. The potentiometer is housed in a robust metal shaft and housing, providing durability and resistance to vibration and shock.
This vintage potentiometer is in new old stock (NOS) condition, meaning it has never been used before and has been stored in its original packaging since it was manufactured in 1954. The NA5-1554-2 is a rare find, as it is becoming increasingly difficult to source vintage electronic components in pristine condition.
In summary, the Bourns 1954 NOS NA5-1554-2 is a high-quality, vintage linear potentiometer that is perfect for projects requiring fine adjustments. Its robust construction, smooth rotation, and NOS condition make it a valuable addition to any electronics collection or project.
Product: Bourns 1954 Nos NA5-1554-2 Resistors
Pros:1. High-quality components: Bourns is a well-known brand in the electronics industry, known for producing high-quality resistors.
2. Precision: The NA5-1554-2 series is rated for a tolerance of 1%, which means they are very precise and can provide stable resistance values.
3. Reliability: The 1954 Nos (New Old Stock) indicates that these resistors are made with older, proven technology that has been time-tested to be reliable.
4. Availability: Since these are older parts, they may still be available even when newer alternatives are out of stock.
Cons:1. Limited availability: Due to their age, these resistors may be hard to find in new condition or in large quantities.
2. Higher cost: Older parts may be more expensive than their newer counterparts due to their rarity.
3. Compatibility concerns: Older parts may not be compatible with newer circuits or equipment, requiring additional modifications or replacements.
Conclusion:Buying Bourns 1954 Nos NA5-1554-2 resistors can be a good option for projects that require high precision and reliability, as well as for those looking for a hard-to-find part. However, it's important to consider the potential limitations in availability and compatibility, as well as the higher cost compared to newer alternatives. Therefore, it's recommended to carefully evaluate the requirements of the project before deciding to purchase these resistors.
