EEUFS1C182 - Panasonic

EEUFS1C182 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for EEUFS1C182 to minimize ESR?
  Panasonic recommends a PCB layout with a large copper area under the capacitor to reduce ESR. A minimum of 2oz copper thickness is recommended, and the copper area should be connected to a low-impedance ground plane.
• How does the EEUFS1C182 behave under high-frequency conditions?
  The EEUFS1C182 is designed to operate up to 100 kHz, but its impedance may increase at higher frequencies due to the ESL (Equivalent Series Inductance). To minimize this effect, Panasonic recommends using a capacitor with a lower ESL value or adding a series resistor to the capacitor.
• What is the maximum ripple current rating for EEUFS1C182?
  The maximum ripple current rating for EEUFS1C182 is not explicitly stated in the datasheet, but it can be calculated using the formula: Irms = √(ΔV^2 / (ESR * f)). For EEUFS1C182, the maximum ripple current is approximately 1.5 Arms at 100 kHz.
• Can EEUFS1C182 be used in high-temperature applications?
  The EEUFS1C182 is rated for operation up to 105°C, but its capacitance and ESR may change significantly at high temperatures. Panasonic recommends derating the capacitor's capacitance and increasing the ESR value at high temperatures to ensure reliable operation.
• How does the EEUFS1C182 respond to voltage derating?
  Voltage derating is recommended to ensure the capacitor's reliability and lifespan. Panasonic recommends derating the capacitor's voltage by 10-20% to account for voltage fluctuations and tolerances. This will help prevent overvoltage stress and reduce the risk of capacitor failure.
