Frequently Asked Questions
Common questions about QXJ2A103 and film capacitors
What applications use a 0.01µF 100V DC film capacitor?
This 0.01µF 100V DC film capacitor serves filtering and energy storage in mid-voltage circuits such as telecom power systems, LED drivers, and bench-top instrumentation power stages.
Can the QXJ2A103 handle high-temperature environments?
The QXJ2A103 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 QXJ2A103?
The QXJ2A103 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 QXJ2A103?
Cross-referencing the QXJ2A103 requires matching capacitance (0.01µF), voltage (100V 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 QXJ2A103?
Yes. Industry best practice is to operate capacitors at 60–80% of their rated voltage. For the QXJ2A103 rated at 100V DC, this means designing your circuit to keep the applied voltage below 80V 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 QXJ2A103?
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 QXJ2A103 shows as out of stock, our sourcing team can typically locate film capacitors within 1–2 weeks through our manufacturer and distributor network.
