FAE Expert Insights
"The 25YXF1000M10X16 is one of my go-to recommendations for general-purpose power supply applications. In my experience supporting power supply designs, this capacitor offers an excellent balance of performance, reliability, and cost. The YXF series provides consistent quality that I have come to rely on over many years. For 12V to 24V systems, the 25V rating provides good margin. I typically recommend operating at 70-80% of rated voltage to maximize lifetime. The 10x16mm size offers good manufacturability while providing adequate ripple current capability for most small to medium power supplies."

Frequently Asked Questions
What is the expected lifetime at different temperatures?
The 25YXF1000M10X16 is rated for 10000 hours at 105C. Following the Arrhenius equation, lifetime approximately doubles for every 10C decrease in temperature. Expected lifetimes: 20000 hours at 95C, 40000 hours at 85C, 80000 hours at 75C, and 160000 hours at 65C. These calculations assume rated voltage and ripple current. Voltage derating further extends lifetime - operating at 80% of rated voltage (20V) typically doubles the expected life. For example, at 85C and 20V, expected lifetime could exceed 80000 hours.
Use temperature derating and voltage derating to maximize capacitor lifetime in your application.
How much ripple current can this capacitor handle?
The 25YXF1000M10X16 has a rated ripple current of 0.58A rms at 100kHz and 105C ambient temperature. At lower temperatures, higher ripple currents are permissible: approximately 0.75A at 85C, 0.95A at 65C, and 1.2A at 45C. The ripple current rating is frequency-dependent - higher frequencies allow increased ripple current due to reduced ESR. At 10kHz, the rating is approximately 0.45A. Exceeding the ripple current rating causes internal heating, accelerating electrolyte evaporation and reducing lifetime. Always calculate expected ripple current and ensure adequate thermal management.
Calculate expected ripple current and verify thermal design for reliable long-term operation.
What is the ESR of this capacitor?
The 25YXF1000M10X16 has a maximum ESR of 0.12 ohm at 20C and 100kHz. ESR varies with temperature and frequency. At -40C, ESR can be 3-5 times higher than at room temperature. At 105C, ESR is typically 20-30% lower than at 20C. ESR also decreases with increasing frequency - at 10kHz, ESR is approximately 2-3 times higher than at 100kHz. For switching power supply applications, the ESR at the switching frequency is critical for calculating output voltage ripple and capacitor heating. Lower ESR results in less heating and better filtering performance.
Consider ESR at your operating frequency and temperature when calculating ripple voltage and thermal performance.
Can this capacitor be used in parallel with others?
Yes, connecting multiple capacitors in parallel is a common practice to increase total capacitance and reduce equivalent ESR. When paralleling capacitors of the same value, the total capacitance is the sum of individual capacitances, and ESR is reduced by the square root of the number of capacitors. For best results, use identical part numbers and place capacitors close together with symmetrical PCB layout. Two 25YXF1000M10X16 in parallel provide 2000uF total capacitance with ESR reduced to approximately 0.06 ohm. Current sharing is naturally balanced when using identical capacitors.
Parallel multiple capacitors for increased capacitance and reduced ESR; use symmetrical layout for current sharing.
What is the leakage current specification?
The maximum leakage current for the 25YXF1000M10X16 is specified as 0.01CV or 3uA, whichever is greater, measured after 5 minutes at rated voltage. For this 1000uF 25V capacitor: 0.01 x 1000uF x 25V = 250uA maximum leakage current. Typical leakage current is much lower, often below 50uA at 25C. Leakage current increases with temperature - approximately doubling for every 10C rise. At maximum rated temperature (105C), leakage current may approach the maximum specification. High leakage current indicates capacitor aging or damage.
Measure leakage current during system testing and maintenance to monitor capacitor health.
