Frequently Asked Questions
Common questions about QXJ2G474 and polyester film capacitors
What applications use a 470nF 400V DC polyester film capacitor?
This 470nF 400V DC polyester film capacitor serves filtering, timing, and energy storage functions in circuits operating within its voltage and temperature ratings.
Can the QXJ2G474 handle high-temperature environments?
The QXJ2G474 is rated for 85°C, which covers standard commercial and light-industrial environments. For installations in enclosed cabinets or hot climates where ambient temperatures exceed 65°C, consider selecting a 105°C-rated alternative for additional thermal margin.
What is the recommended PCB footprint for the QXJ2G474?
The QXJ2G474 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 QXJ2G474?
Cross-referencing the QXJ2G474 requires matching capacitance (470nF), voltage (400V DC), temperature rating (85°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 QXJ2G474?
Yes. Industry best practice is to operate capacitors at 60–80% of their rated voltage. For the QXJ2G474 rated at 400V DC, this means designing your circuit to keep the applied voltage below 320V 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 QXJ2G474?
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 QXJ2G474 shows as out of stock, our sourcing team can typically locate high-voltage polyester film capacitors within 1–2 weeks through our manufacturer and distributor network.
