Review CORNELL DUBILIER Nos Nib Uf 450v Screw base Can Capacitor

The Cornell Dubilier Kr588A NOS UF 450V screw-base capacitor is a vintage electrical component, manufactured in 1971. This capacitor is a part of Cornell Dubilier's long-lasting and high-quality line of electrolytic capacitors. The Kr588A model is specifically designed for industrial and military applications, requiring reliable and stable power supply.

This capacitor features a screw-base termination, making it easy to install and replace. The UF designation indicates that it is unified, meaning that it can be used in both AC and DC circuits. The capacitance value is 4700 F, and the voltage rating is 450 volts. The component is rated for a ripple current of 5.2 amperes and a maximum operating temperature of 65 C.

The Kr588A NOS (New Old Stock) capacitor is a "no-leak" design, which means that it uses a special electrolyte that does not evaporate or leak out over time. This makes it an ideal choice for applications where long-term stability and reliability are essential. The capacitor is also sealed in a rugged and moisture-resistant aluminum can, further enhancing its durability and protection against environmental hazards.

The Kr588A NOS UF 450V screw-base capacitor is a high-performance component, engineered to deliver consistent and stable power supply even under heavy loads or harsh operating conditions. It is an essential component for various industrial and military applications, including power supplies, filters, and voltage regulators. With its proven track record of reliability and longevity, this capacitor is a smart investment for any project that demands high-quality and dependable electrical components.

In summary, the Cornell Dubilier Kr588A NOS UF 450V screw-base capacitor is a vintage and highly regarded electrical component, designed for industrial and military applications. It features a screw-base termination, a capacitance value of 4700 F, a voltage rating of 450 volts, and a ripple current of 5.2 amperes. The capacitor is a "no-leak" design, sealed in a rugged aluminum can, and is ideal for applications where long-term stability and reliability are essential.

The Cornell Dubilier Kr588A NOs UF 450V screw-base capacitor, with a manufacturing year of 1971, is an obsolete electrical component. Analyzing the pros and cons of purchasing such a capacitor can help you make an informed decision.

Pros:

1. Availability of Stock: Older capacitors, like the Kr588A, may still be available in stock from surplus suppliers, electronics stores, or specialized distributors.

2. Long-term Durability: Capacitors manufactured in the past often had higher quality components and construction techniques, which could result in better long-term performance and reliability.

3. Cost-effective: Obtaining an older capacitor can be more cost-effective than purchasing a new one, especially if you need a large quantity or a specific capacitance value that is no longer in production.

Cons:

1. Limited Availability: Older capacitors may not be readily available, requiring more time and effort to locate and purchase.

2. Compatibility: Older capacitors may not be directly compatible with newer systems or equipment. You may need to check the electrical specifications and ensure that the older capacitor can safely replace the newer one.

3. Risk of Failure: Older capacitors, especially those that are not in use, may have deteriorated over time, increasing the risk of failure.

4. Lack of Warranty: When purchasing an older capacitor, there is a likelihood that it may not come with a warranty.

Ending Conclusion:

The decision to purchase a Cornell Dubilier Kr588A NOs UF 450V screw-base capacitor, manufactured in 1971, depends on your specific use case and requirements. If you need a large quantity or a specific capacitance value that is no longer in production, purchasing an older capacitor can be a cost-effective solution. However, there is a risk of compatibility issues and potential failure, so it is essential to ensure that the older capacitor can safely replace the newer one and perform the required function reliably. If possible, it is recommended to consider alternative solutions, such as modern capacitors or capacitor banks, which may offer better compatibility, reliability, and warranty coverage.

Details:

The can cap is fine. Please see my pictures for details. The box is in OK condition but has some heavy damage on the bottom. I have more capacitors and other vintage electronics listed feel free to take a look!, Up for sale here is this NOS NIB Cornell Dubilier KR588A screw-base can capacitor, dated 1971 Made in USA.This has very tiny dent but otherwise great.

If you would like to buy multiple items, I do combine shipping. It is marked as having two sections of 8 uf 450v. The sections test around 12-13 uf and show fairly low leakage, so this should work fine. You should bring it up on a Mauriac before applying full voltage .
