Frequently Asked Questions
Common questions about 350UVZ4R7 and high temperature radial capacitors
What applications use a 4.7µF 350V DC high temperature radial capacitor?
This 4.7µF 350V DC high temperature radial capacitor serves filtering, timing, and energy storage functions in circuits operating within its voltage and temperature ratings.
Can the 350UVZ4R7 handle high-temperature environments?
Yes. The 350UVZ4R7 is rated for 105°C continuous operation, making it suitable for enclosed industrial cabinets, engine compartments, and outdoor equipment where ambient temperatures regularly exceed 70°C. For applications above 85°C ambient, consider derating the ripple current per the manufacturer's derating curve to maintain expected service life.
What is the recommended PCB footprint for the 350UVZ4R7?
The 350UVZ4R7 uses radial mounting. Refer to the manufacturer datasheet for the recommended land pattern. For through-hole parts, ensure the drill diameter is 0.2–0.3mm larger than the lead diameter for reliable hand or wave soldering.
What capacitors can replace the 350UVZ4R7?
Cross-referencing the 350UVZ4R7 requires matching capacitance (4.7µF), voltage (350V DC), temperature rating (105°C), and physical dimensions. ESR and ripple current ratings must also meet or exceed the original spec for reliable operation. Contact our technical team at 800-731-1433 for verified cross-reference options — we maintain compatibility data across major manufacturers.
Should I derate the voltage when using the 350UVZ4R7?
Yes. Industry best practice is to operate capacitors at 60–80% of their rated voltage. For the 350UVZ4R7 rated at 350V DC, this means designing your circuit to keep the applied voltage below 280V under all conditions including transients. Voltage derating significantly extends capacitor life — each 10% reduction in applied voltage can roughly double the expected service life for electrolytic types.
What is the lead time for the 350UVZ4R7?
In-stock items ship same-day when ordered before 3 PM EST, with standard delivery of 2–5 business days within the continental US. If the 350UVZ4R7 shows as out of stock, our sourcing team can typically locate high-voltage high temperature radial capacitors within 1–2 weeks through our manufacturer and distributor network.
