Frequently Asked Questions
What electrical specifications define the Panasonic EEE-FC1V220P and what voltage margin should designers apply?
The EEE-FC1V220P is rated at 22 µF capacitance and 35 V working voltage, with a 105°C maximum operating temperature. Standard practice for aluminum electrolytic capacitors recommends a 20% voltage derating, meaning the capacitor should be used on rails not exceeding 28 V in continuous operation to ensure long-term reliability and meet its rated service life of typically 2000 hours at rated temperature.
How does the EEE-FC1V220P's SMD construction compare to a through-hole equivalent for high-density PCB designs?
The SMD package of the EEE-FC1V220P allows direct reflow soldering and occupies a smaller PCB footprint than equivalent through-hole capacitors, enabling placement on densely populated boards where automated pick-and-place assembly is required. The absence of through-hole leads also improves high-frequency performance by minimizing lead inductance, which can otherwise degrade filtering effectiveness at frequencies above 10 kHz in switching power supply applications.
In which switching converter topologies is the 22 µF, 35 V EEE-FC1V220P most commonly specified as an output filter capacitor?
The EEE-FC1V220P is commonly specified in buck and boost converter output stages operating at 12 V to 28 V rails and switching frequencies of 100 kHz to 500 kHz. At 22 µF, it provides sufficient bulk capacitance to limit output voltage ripple to acceptable levels while the low ESR of the FC series reduces resistive ripple components, making it a practical choice for single-phase DC-DC converters powering digital loads such as FPGAs and DSPs.
What lifespan and derating considerations apply when using the EEE-FC1V220P in an industrial 105°C environment?
At the rated 105°C operating temperature and 35 V working voltage, the EEE-FC1V220P delivers its rated load life of approximately 2000 hours. For extended field life in industrial equipment with 10-year operational requirements, designers should derate the operating temperature to 85°C or lower, which can extend capacitor life by a factor of 4 to 8 per the Arrhenius model, targeting 8000 hours or more of reliable operation in harsh environments.
