Applications
The Panasonic EEE-TK1C222AM is designed for bulk capacitance and ripple filtering in SMD power supply circuits, DC-DC converters, and motor drive output stages where 2200 µF at 16 V is required in a surface mount form factor. Its low ESR characteristics make it ideal for switching regulator output filtering in servers, telecommunications equipment, and industrial control systems where reducing voltage ripple below 50 mV is critical for downstream circuitry stability. The 105°C rating enables use in automotive, industrial IoT, and LED driver power stages operating in high-ambient-temperature enclosures.

Frequently Asked Questions
What are the key electrical specifications of the Panasonic EEE-TK1C222AM capacitor?
The EEE-TK1C222AM is a 2200 µF aluminum electrolytic capacitor with a 16 V rated voltage and low ESR design from Panasonic's TK series. It operates across a temperature range of -55°C to +105°C and is optimized for high-ripple current applications in SMD switching power supplies, offering superior capacitance density compared to ceramic alternatives at equivalent voltage ratings.
In which power supply topologies does the EEE-TK1C222AM provide the most benefit as an output filter capacitor?
The EEE-TK1C222AM's 2200 µF capacitance and low ESR make it ideal as output filter capacitors in buck converters switching at 100 kHz to 500 kHz, where it reduces output voltage ripple to below 20 mV at load currents up to 10 A. It also excels in boost converter input filtering, LLC resonant converter DC link stages, and point-of-load regulators in telecom infrastructure where bulk SMD capacitance is needed within tight PCB footprint constraints.
How does the TK series SMD package of EEE-TK1C222AM compare to through-hole aluminum electrolytic capacitors at 2200 µF?
The TK series SMD package reduces board height by 30-50% compared to equivalent through-hole 2200 µF radial capacitors, enabling automated pick-and-place assembly with reflow soldering at up to 260°C peak temperature. The SMD configuration eliminates the need for through-holes, saving PCB area and improving vibration resistance due to the lower mechanical stress on solder joints compared to tall through-hole component leads in industrial and automotive environments rated for 15G vibration.
What ripple current capability and ESR should designers expect from EEE-TK1C222AM at 100 kHz?
Panasonic TK series capacitors like the EEE-TK1C222AM are rated for ripple currents of approximately 1500 mA to 3000 mA at 100 kHz depending on case size, with ESR values typically below 30 milliohms at 100 kHz and 20°C. The 105°C maximum operating temperature allows a thermal derating to 70% rated ripple current at maximum ambient, making it suitable for industrial server power supplies and motor drive output stages requiring sustained high-ripple filtering over 10+ year service lives.
