Frequently Asked Questions
What are the key electrical ratings of the Panasonic EEE-FK0J221AP capacitor?
The EEE-FK0J221AP is rated at 220 µF capacitance and 6.3 V working voltage with a ±20% tolerance. These specifications make it a standard bulk filtering capacitor for low-voltage power rails in consumer electronics, mobile device chargers, and embedded power management circuits operating below 6.3 V.
How does the SMD package of the EEE-FK0J221AP benefit high-volume PCB manufacturing?
The EEE-FK0J221AP uses a surface mount (SMD) package compatible with automated SMT pick-and-place and reflow soldering at standard lead-free temperatures up to 260°C. Combined with full-reel tape-and-reel packaging, it supports uninterrupted high-volume production lines, reducing manual handling and improving placement accuracy for the 220 µF capacitor across thousands of boards.
In which power supply filtering designs is the EEE-FK0J221AP typically used?
The EEE-FK0J221AP is commonly used as an output bulk capacitor in 5 V or 3.3 V DC-DC buck converters and LDO regulator circuits, where 220 µF at 6.3 V provides effective ripple attenuation. It also serves as a decoupling reservoir for microcontroller power rails in IoT devices, wearables, and portable consumer electronics requiring compact SMD capacitors with reliable 6.3 V rated performance.
Can the EEE-FK0J221AP be substituted with a tighter-tolerance variant, and what trade-offs exist?
The EEE-FK0J221AP carries a ±20% tolerance, meaning actual capacitance ranges from 176 µF to 264 µF. Substituting a ±10% or ±5% tolerance aluminum electrolytic at 220 µF and 6.3 V would improve worst-case ripple predictions in sensitive power designs, but typically at higher cost and potentially a larger SMD footprint. For most bulk decoupling at 6.3 V, the ±20% version is sufficient and more economical.
