Frequently Asked Questions
What are the key electrical ratings of the EEE-FC1V221AP and what ripple current can it handle?
The EEE-FC1V221AP is rated at 220 µF capacitance with a 35 V maximum voltage and ±20% tolerance. The Panasonic FC series low-ESR construction typically supports ripple current ratings of 390 mA to 700 mA at 100 kHz depending on the case size, making it suitable for output filtering in 12 V to 24 V switching power supplies operating at frequencies above 50 kHz.
What SMD case size does the EEE-FC1V221AP use and how does it fit on a standard PCB land pattern?
The EEE-FC1V221AP is supplied in a standard SMD aluminum electrolytic can, typically a 10 mm diameter by 10 mm height radial package with surface-mount leads. The PCB land pattern uses two pads spaced 5 mm apart with a pad size matching IPC-7351 recommendations, compatible with standard SMT reflow profiles using SAC305 solder paste at peak temperatures of 260°C.
What is the operating temperature range of the EEE-FC1V221AP and how does it affect lifetime?
The Panasonic FC series operates across -55°C to +105°C, with rated endurance of 2000 hours at 105°C full rated voltage. Operating at lower temperatures such as 85°C typically doubles or quadruples the expected capacitor lifetime based on the Arrhenius rule, making this part well suited for industrial equipment that must meet 10-year field reliability targets in moderately hot environments.
Why would an engineer select EEE-FC1V221AP over a standard 35 V electrolytic for a DC-DC converter design?
The Panasonic FC series offers lower ESR than general-purpose aluminum electrolytic capacitors of the same 220 µF 35 V rating, resulting in reduced power dissipation and lower output voltage ripple at 100 kHz switching frequencies. The FC series is also manufactured to tighter process controls, providing more consistent batch-to-batch capacitance and ESR values that simplify stability compensation in closed-loop power supply designs.
How many units are supplied per full reel of EEE-FC1V221AP and what does that mean for procurement planning?
Panasonic full-reel SMD electrolytic capacitors are typically supplied in quantities of 500 units per reel for large-can sizes in the 10 mm diameter range. At 220 µF 35 V this means ordering one reel covers approximately 500 PCBs using 1 capacitor each, making full-reel purchasing cost-effective at production volumes above 200 units where per-unit price savings versus cut-tape exceed the minimum order quantity premium.
