EEUFC1V121(B) Frequently Asked Questions (FAQ)

  • The recommended land pattern for EEUFC1V121B can be found in the Panasonic Electronic Components' recommended footprint document or by contacting their technical support. A general guideline is to use a land pattern with a pad size of 2.5mm x 1.5mm and a spacing of 1.5mm between pads.

  • The EEUFC1V121B is a moisture-sensitive device and should be handled according to the JEDEC J-STD-033 standard. This includes storing the components in a dry environment, using a dry pack or nitrogen-filled packaging, and baking the components before reflow soldering if they have been exposed to moisture.

  • The maximum reflow temperature for EEUFC1V121B is 260°C, with a peak temperature of 250°C. It is recommended to follow the reflow profile recommended by Panasonic Electronic Components or a similar profile with a ramp-up rate of 3°C/s and a dwell time of 30-60 seconds above 220°C.

  • The EEUFC1V121B is a radial lead type capacitor and can be used in high-vibration environments. However, it is recommended to follow the recommended mounting and soldering guidelines to ensure the capacitor is securely attached to the PCB. Additionally, it is recommended to perform vibration testing to ensure the capacitor meets the required reliability standards.

  • The equivalent series resistance (ESR) of the EEUFC1V121B can be determined by measuring the impedance of the capacitor at high frequencies (e.g. 100 kHz) using an impedance analyzer or a network analyzer. The ESR can also be calculated using the capacitor's datasheet values and the following formula: ESR = (ESL / (2 * π * f * C)), where ESL is the equivalent series inductance, f is the frequency, and C is the capacitance.
