EEUFS1E122 - Panasonic

EEUFS1E122 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for EEUFS1E122?
  Panasonic recommends a PCB layout with a solid ground plane and a via under the capacitor to reduce ESL and ESR. A minimum of 1.5mm clearance around the capacitor is also recommended.
• How do I handle the EEUFS1E122 during assembly to prevent damage?
  Handle the capacitor by the body, not the leads, to prevent damage. Avoid bending or twisting the leads, and use a pick-and-place machine or a vacuum pickup tool to minimize mechanical stress.
• What is the derating curve for EEUFS1E122 at high temperatures?
  Panasonic provides a derating curve in the datasheet, but it's limited to 125°C. For temperatures above 125°C, consult with Panasonic's application engineers or use a more conservative derating curve to ensure reliable operation.
• Can I use EEUFS1E122 in a high-vibration environment?
  Yes, but ensure that the capacitor is properly secured to the PCB using a suitable mounting method, such as soldering or adhesive. Consult with Panasonic's application engineers for specific guidance on vibration testing and validation.
• How do I determine the ESR of EEUFS1E122 at high frequencies?
  Use a network analyzer or an impedance analyzer to measure the ESR of the capacitor at high frequencies. Panasonic provides ESR data up to 100 kHz in the datasheet, but you may need to measure it at higher frequencies depending on your application.
