The Sprague 5GAD40 NOS 5GA-D40 Ceramic Disc Capacitor is a high-performance electronic component with a capacitance value of 0.047 F (0.00047 F) at 1000 volts. This component is a non-obsolete stock (NOS) item, meaning it is a previously manufactured component that is still available for purchase but is no longer in production.
This capacitor is a radial lead design, with a diameter of 25.4 mm (1.0 inches) and a height of 12.7 mm (0.5 inches). It has two radial leads, spaced 180 degrees apart, and is suitable for surface mounting applications. The capacitor's body is made of ceramic material, which provides excellent electrical insulation and high dielectric constant, making it ideal for use in various electronic circuits, particularly those requiring high capacitance and voltage handling capabilities.
The 5GAD40 has a temperature coefficient of -200 ppm/ C to 200 ppm/ C. This means that the capacitance value of the component changes slightly with temperature. However, this temperature coefficient is relatively low, which makes the capacitor suitable for use in applications where temperature stability is important.
The capacitor's voltage rating of 1000 volts indicates that it can withstand an applied voltage of up to 1000 volts without breaking down or failing. This makes it suitable for use in high-voltage electronic circuits, such as power supplies, filters, and voltage regulators.
The capacitance value of the 5GAD40 is specified as 4000 pF (picofarads) at 125 C. This is referred to as the capacitor's "equivalent series inductance capacitance" (ESL-C). This value is important in high-frequency applications, as it affects the component's ability to store and release energy quickly. The lower the ESL-C value, the better the component's high-frequency performance.
In summary, the Sprague 5GAD40 NOS 5GA-D40 Ceramic Disc Capacitor is a high-performance electronic component with a capacitance value of 0.047 F at 1000 volts. It is a radial lead design with a temperature coefficient of -200 ppm/ C to 200 ppm/ C, a voltage rating of 1000 volts, and a capacitance value of 4000 pF at 125 C. It is a non-obsolete stock item that is suitable for use in various electronic circuits requiring high capacitance and voltage handling capabilities.
The Sprague 5GAD40 NOS 5GA-D40 ceramic disc capacitor, model number 004uf 1000v 4000pf, is a type of capacitor used in various electronic applications. Here are some pros and cons of buying this particular capacitor:
Pros:1. High Voltage Rating: With a voltage rating of 1000V, this capacitor can handle high voltage applications, making it suitable for use in power electronics, radio-frequency circuits, and other high voltage circuits.
2. Large Capacitance: The capacitance value of 0.004uf and the equivalent value of 4000pf is relatively large, making it suitable for use in filtering and coupling applications where large capacitance is required.
3. Ceramic Construction: Ceramic capacitors are known for their excellent high-frequency performance and stability. They are also compact and lightweight, making them ideal for use in space-constrained applications.
4. NOS (New Old Stock): New Old Stock (NOS) capacitors are often preferred over new capacitors because they are known to have better aging characteristics and stability. This can be particularly important in applications where long-term reliability is critical.
Cons:1. Limited Availability: Due to their older design and smaller production volume, NOS capacitors like the Sprague 5GAD40 may be harder to find and more expensive than newer, mass-produced capacitors.
2. Lower Ripple Current Capability: Ceramic capacitors generally have lower ripple current capability compared to electrolytic capacitors. This means that they may not be suitable for applications where large currents are required to be filtered or smoothed.
3. Temperature Sensitivity: Ceramic capacitors are sensitive to temperature changes, which can affect their capacitance value and stability. This can be mitigated by careful temperature control and selection of capacitors with appropriate temperature coefficients.
In conclusion, the Sprague 5GAD40 NOS 5GA-D40 ceramic disc capacitor offers high voltage handling capability, large capacitance, and excellent high-frequency performance, making it suitable for use in various electronic applications where reliability and stability are critical. However, its limited availability, lower ripple current capability, and temperature sensitivity are important considerations to keep in mind. Ultimately, the decision to buy this capacitor depends on the specific requirements of your application and the trade-offs you are willing to make. If high voltage, large capacitance, and stability are your primary concerns, then this capacitor may be worth considering despite its limitations. On the other hand, if low cost, high ripple current capability, or temperature insensitivity are more important factors, then you may want to explore other options.
