Review WESTERN ELECTRIC 178279 Evacuated Precision Resistors Unusual
The D-178279 Western Electric 178279 Evacuated Precision Resistors, model D178270, are a remarkable addition to any electronic circuitry. These resistors are renowned for their exceptional accuracy and stability, making them an ideal choice for high-precision applications.
The D-178279 resistors are part of Western Electric's long-standing legacy in the field of telecommunications and electronics. They are manufactured using the unique evacuated technology, which involves removing air from the resistor element, thus eliminating the effects of temperature and humidity on resistance value. This results in a remarkably stable and accurate resistance value over a wide range of temperatures.
The resistors have a nominal value of 100 ohms, with a tolerance of /-0.005%. This high degree of accuracy is achieved through a meticulous manufacturing process that involves the use of high-purity materials and stringent quality control measures. The resistors are also available in a variety of other nominal values, from 1 ohm to 100 megohms, making them versatile for a wide range of applications.
The D-178279 resistors have a power rating of 0.25 watts, making them suitable for low-power applications. They also have a maximum operating temperature of 150 degrees Celsius, ensuring reliable performance even under harsh operating conditions.
The resistors are packaged in hermetically sealed glass tubes, providing protection against moisture and contaminants. This ensures a long lifespan and reliable performance, even in demanding environments.
In conclusion, the D-178279 Western Electric 178279 Evacuated Precision Resistors, model D178270, are a must-have for any electronics enthusiast or professional seeking unparalleled accuracy and stability in their circuitry. Their unique manufacturing process, high degree of accuracy, and robust construction make them a reliable and long-lasting choice for a wide range of applications.
Pros of buying D-178279 Western Electric Evacuated Precision Resistors:1. High Precision: These resistors are known for their high precision and accuracy, making them ideal for applications that require precise electrical resistance values.
2. Stable Resistance: They have a low temperature coefficient, ensuring that the resistance value remains stable over a wide temperature range.
3. Long Lifespan: The vacuum sealed design of these resistors helps to prevent moisture and contaminants from entering, resulting in a longer lifespan compared to regular resistors.
4. High Power Handling: They can handle high power levels, making them suitable for applications that require high power dissipation.
5. Low Noise: They have a low noise level, which is beneficial for applications that require low-noise signals, such as in audio and RF applications.
Cons of buying D-178279 Western Electric Evacuated Precision Resistors:1. Cost: These resistors are typically more expensive than regular resistors due to their high precision and unique design.
2. Availability: They may not be readily available in retail stores, and you may need to order them online or from specialized suppliers.
3. Sensitive to Vibration and Shock: Due to their delicate design, they are more susceptible to damage from vibration and shock than regular resistors.
4. Limited Wattage Rating: Although they have a high power handling capability, their wattage rating is still limited compared to some other types of resistors.
Conclusion:D-178279 Western Electric Evacuated Precision Resistors are a high-quality option for applications that require precise electrical resistance values, low noise, and high power handling. While they may be more expensive than regular resistors, their long lifespan and stability make them a worthwhile investment in certain applications. However, their sensitivity to vibration and shock and limited wattage rating may be drawbacks for some users. Ultimately, the decision to purchase these resistors should be based on the specific requirements of your application.
Recommendation:If you require high precision and accuracy in your electrical resistance values, and can afford the additional cost, then D-178279 Western Electric Evacuated Precision Resistors are a great option. However, if cost is a concern or your application does not require their unique features, then regular resistors may be a more suitable and cost-effective choice.
