What are the key features of EEE-TC1E221P?
- 220 µF capacitance at 25 V with 20% tolerance for robust bulk energy storage in power conversion stages
- Ultra-long 3000-hour rated lifetime at 125°C ensuring reliability in high-temperature industrial environments
- Low ESR of 0.15 Ohm supporting high ripple current handling up to 750 mA for switching regulator output filters
- SMD 10 mm x 10.2 mm can package enabling reflow soldering in automated surface-mount assembly lines
- Panasonic TC series construction providing stable capacitance over wide temperature ranges from -40°C to +125°C
What is EEE-TC1E221P used for?
The EEE-TC1E221P is used as an output filter capacitor in switching power supplies, DC-DC converters, and motor drive inverter stages where high ripple current capability up to 750 mA and low ESR are required to maintain output voltage stability. Its 3000-hour lifetime at 125°C makes it suitable for automotive under-hood electronics, industrial servo drives, and LED lighting drivers operating in harsh thermal environments. The part is also applied in power-over-Ethernet midspan circuits and server power supply units as a bulk decoupling capacitor on 24 V and 12 V intermediate bus rails.

Frequently Asked Questions
What are the key electrical ratings of the EEE-TC1E221P capacitor?
The EEE-TC1E221P is rated at 220 µF capacitance and 25 V working voltage with a ±20% capacitance tolerance. Its equivalent series resistance is 0.15 Ohm, and the maximum allowable ripple current is 750 mA at 120 Hz and 105°C. These specifications make it appropriate for output filtering in 12 V to 24 V DC-DC converter designs with moderate switching frequencies.
How does the EEE-TC1E221P's 3000-hour lifetime rating at 125°C affect product design decisions?
A 3000-hour rating at 125°C corresponds to over 10 years of service life when derated to an operating temperature of 85°C, which roughly doubles lifespan for every 10°C reduction. This makes the EEE-TC1E221P suitable for automotive infotainment systems, industrial PLCs, and outdoor LED drivers where electrolytic capacitor lifetime is a primary design reliability concern, avoiding costly field replacements over a 10-year product lifetime.
How does the 0.15 Ohm ESR of EEE-TC1E221P compare to standard electrolytic capacitors for switching regulator use?
Standard general-purpose aluminum electrolytic capacitors in the same 220 µF / 25 V class typically have ESR values of 0.5 Ohm to 1.5 Ohm, whereas the EEE-TC1E221P's 0.15 Ohm ESR is 3× to 10× lower. This low ESR reduces output voltage ripple by a factor of 3 to 10 at the same 750 mA ripple current, enabling tighter output voltage regulation in buck converter designs without paralleling multiple capacitors.
For a compact SMD power supply board, what PCB footprint does the EEE-TC1E221P occupy?
The EEE-TC1E221P uses a 10 mm diameter by 10.2 mm height SMD can, with a standard pad footprint of approximately 10 mm x 10.5 mm on the PCB. Compared to a through-hole 220 µF / 25 V capacitor requiring a 5 mm drill pattern and 6.3 mm body clearance, the SMD package allows placement on either board side during reflow assembly, reducing component height constraints in low-profile enclosures below 15 mm.
