- 125°C maximum operating temperature with 3000-hour endurance for long-life industrial and automotive use
- Low ESR of 0.2 Ω enabling efficient ripple suppression in DC-DC converter output stages
- 410 mA ripple current rating supporting high-frequency switching power supply loads
- Compact 8 × 10.2 mm SMD package for space-efficient PCB mounting
Applications
The EEE-TC1A331UP is engineered for DC-DC converter output filtering and bulk capacitance on 5 V and 10 V rails in industrial control systems, server power supplies, and networking equipment that demand long-life 125°C-rated components. Its low 0.2 Ω ESR makes it particularly effective at suppressing high-frequency switching noise in synchronous buck converters operating at 200 kHz to 2 MHz. The 3000-hour endurance rating also qualifies it for telecommunications infrastructure and HVAC control boards where electrolytic capacitors must maintain specification over multi-year continuous operation.

Frequently Asked Questions
What makes the EEE-TC1A331UP's 3000-hour endurance rating significant for industrial power supply designs?
The 3000-hour endurance at 125°C is approximately three times longer than standard 1000-hour-rated SMD electrolytic capacitors, significantly extending the service life of power supplies in industrial 24/7 environments. For a 330 µF, 10 V filter capacitor in a server or telecom rack running at 85°C ambient, Arrhenius life-doubling rules project operational life beyond 10 years, reducing maintenance downtime.
How does the 0.2 Ω ESR of EEE-TC1A331UP benefit a 5 V synchronous buck converter?
At 0.2 Ω ESR, the EEE-TC1A331UP dissipates less than 34 mW of heat at its 410 mA ripple current rating, keeping the output voltage ripple contribution from ESR below 82 mV peak-to-peak. In a 5 V buck converter switching at 500 kHz, this low ESR maintains output ripple within typical 1% specifications without requiring paralleled capacitors, saving board space.
Can the EEE-TC1A331UP operate reliably in a 125°C ambient environment without derating its 330 µF capacitance?
Yes. The EEE-TC1A331UP is rated for full 330 µF capacitance across its entire -55°C to +125°C operating range. Unlike general-purpose 85°C-rated electrolytics that must be derated above 70°C, this capacitor maintains its specification at maximum temperature for 3000 hours, making it suitable for under-bonnet automotive and high-ambient industrial enclosures without board-level thermal management compromises.
How does EEE-TC1A331UP's 8 × 10.2 mm SMD package compare to through-hole equivalents for high-density board layouts?
The 8 mm diameter SMD package of the EEE-TC1A331UP occupies roughly half the PCB footprint of a comparable through-hole radial capacitor (typically 10 mm diameter plus lead clearance), eliminating the need for through-board drilling. Tape-and-reel packaging at 1000 units per reel supports automated SMD reflow assembly, reducing per-unit placement cost versus hand-soldered through-hole components.
