( Brand: Sprague ), ( Manufacturer Part Number: TVL-4714.4 ), ( Part Type: Capacitor Twist ), ( Country/region Of Manufacture: United States )
The Sprague TVL-4714 NOS Capacitor is a high-quality, vintage component that is still highly sought after in electronic circles due to its superior performance characteristics. This twist-lok capacitor is a true NOS (New Old Stock) item, meaning it has been manufactured and stored for an extended period, preserving its original specifications and performance.
The TVL-4714 is a 30-20-160-40 microfarad capacitor, which refers to its electrical rating. The 30-20-160 indicates the capacitance value, with 30 being the primary value, 20 the tolerance, and 160 the voltage rating. The 40 refers to the temperature coefficient, which is a measure of how much the capacitance changes with temperature.
This capacitor is known for its twist-lok design, which provides a secure mechanical connection while allowing for easy installation and removal. The twist-lok design also helps to prevent accidental disconnection, making it ideal for applications where reliability is crucial.
The Sprague TVL-4714 NOS Capacitor is made from high-quality materials, including a heavy-duty aluminum case and a Mylar dielectric film. The Mylar dielectric provides excellent electrical performance, with low loss and high stability over time. The capacitor also features a silver-mica dielectric, which further enhances its performance and stability.
In terms of electrical specifications, the TVL-4714 has a voltage rating of 400 volts RMS, with a maximum allowable voltage of 500 volts. It has a power factor of 0.99, indicating that it is highly efficient at storing and releasing electrical energy. The capacitance tolerance of 20% ensures that the capacitor will perform within a relatively narrow range of values, making it ideal for applications where precise capacitance values are required.
In conclusion, the Sprague TVL-4714 NOS Capacitor is a high-performance, vintage component that is still highly sought after in electronic circles. Its twist-lok design, high-quality materials, and excellent electrical specifications make it an ideal choice for applications that require reliable, stable, and high-performance capacitance. Whether you're restoring vintage audio equipment, building a high-fidelity audio system, or working on any other electronic project, the TVL-4714 is a component that you can trust to deliver reliable performance over the long term.
Pros of buying Sprague TVL-4714 NOS capacitors (Twist-Lok, 30-20-160-40 uF):1. High Quality: Sprague is a well-known brand in the capacitor industry, known for producing high-quality capacitors with tight tolerances and long lifespans.
2. NOS (New Old Stock): These capacitors are new but have been in storage for an extended period, which can add a vintage touch to your electronic project and potentially improve sound quality in audio applications.
3. Twist-Lok Terminals: The Twist-Lok terminals make it easy to install the capacitors without the need for soldering. This can be particularly useful in projects where space is limited.
4. Large Capacitance: The 40 uF capacitance is suitable for various electronic applications, including audio, power supply filtering, and DC blocking.
Cons of buying Sprague TVL-4714 NOS capacitors (Twist-Lok, 30-20-160-40 uF):1. Limited Availability: Due to their age and popularity, NOS capacitors can be challenging to find and may be more expensive than new capacitors.
2. Higher Price: Compared to new capacitors, NOS capacitors can be significantly more expensive due to their scarcity and the perceived value of vintage parts.
3. Potential Variations: Since these capacitors have been in storage for an extended period, there may be variations in their electrical characteristics, such as capacitance, leakage current, and voltage rating.
Conclusion: If you're looking for high-quality capacitors with a vintage touch for your electronic project and don't mind the higher price, Sprague TVL-4714 NOS capacitors (Twist-Lok, 30-20-160-40 uF) are an excellent choice. However, if you're on a budget or prefer new capacitors with consistent electrical characteristics, you may want to consider other options. Ultimately, the decision depends on your specific needs, preferences, and budget.
I have limited knowledge of the items. I have no way of testing items. I am doing my best to describe the items.Please look at pictures. Some of the boxes shower.
So I will notate what Cantrell you about an item to the best of my ability. I still have lots of parts, test equipment, tools and other goodies tousle. He has passed away and I am now selling off his old stock tools.
