Frequently Asked Questions
Common questions about 25RTAR1 and tantalum capacitors
What applications use a 0.1µF 25V DC tantalum capacitor?
A 0.1µF 25V DC capacitor is typically used for high-frequency bypass near digital ICs, coupling in signal chains, and EMI suppression. Place as close as possible to the power pins of the IC being decoupled for effective noise filtering.
Can the 25RTAR1 handle high-temperature environments?
The 25RTAR1 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 25RTAR1?
The 25RTAR1 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 25RTAR1?
Cross-referencing the 25RTAR1 requires matching capacitance (0.1µF), voltage (25V 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 25RTAR1?
Yes. Industry best practice is to operate capacitors at 60–80% of their rated voltage. For the 25RTAR1 rated at 25V DC, this means designing your circuit to keep the applied voltage below 20V 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 25RTAR1?
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 25RTAR1 shows as out of stock, our sourcing team can typically locate tantalum capacitors within 1–2 weeks through our manufacturer and distributor network.
