RDS0E331MCNAFEGS

The RDS0E331MCNAFEGS is a conductive polymer aluminum solid electrolytic capacitor in a compact SMD can package. It delivers high capacitance (330 µF) and low ESR optimized for surface-mount designs that must operate reliably at elevated temperatures.

Designed for applications that require high ripple-current handling and long-term operation at up to 125°C, this Nichicon RDS series part combines a 2.5 V rating with a robust 3000-hour load life at 125°C and lead-free reflow compatibility to 260°C peak.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 2.5 V provides substantial bulk charge storage in a small footprint for low-voltage systems.
• Conductive polymer construction — Solid electrolyte architecture for high capacitance density and stable electrical characteristics.
• High-temperature endurance — Rated for an operating temperature range of −55°C to 125°C with a specified load life of 3000 hours at 125°C.
• Low ESR and high ripple capability — ESR of 25 mΩ (measured at 100 kHz, 20°C) and ripple current performance up to 1.05 A at 300 kHz support high-frequency and high-current applications.
• SMD can package — Compact dimensions L: 5.7 × D: 6.3 mm and surface-mount land size of 6.5 × 6.5 mm enable dense PCB placement; package is compatible with lead‑free reflow up to 260°C peak.
• Leakage and tolerance — Capacitance tolerance ±20% and leakage current specification consistent with conductive polymer aluminum electrolytic behavior (datasheet conditioning applies).
• Regulatory compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High-temperature surface-mount power modules — Bulk energy storage and smoothing where elevated ambient or process temperatures require extended high-temperature endurance.
• Compact decoupling and bulk filtering — Low ESR and high capacitance in a small SMD can for decoupling and bulk filtering in space-constrained boards.
• High-frequency switching circuits — Ripple current capability and low ESR measured at 100 kHz make this part suitable for switching regulator output stages and high-frequency power assemblies.

Unique Advantages

• Extended high-temperature life: 3000 hours at 125°C provides predictable endurance for designs exposed to sustained elevated temperatures.
• High ripple handling: Rated ripple current specifications (105 mA at 120 Hz and 1.05 A at 300 kHz) enable reliable performance under AC stress and switching loads.
• Low ESR at high frequency: 25 mΩ ESR at 100 kHz reduces losses and improves thermal performance in high-frequency circuits.
• Compact SMD can: 6.3 × 5.7 mm case size with a small recommended land pattern supports dense PCB layouts while remaining compatible with lead‑free reflow processes.
• Designed for robust leakage behavior: Leakage current specifications and conditioning guidance support predictable in-circuit behavior after application of rated voltage.
• RoHS compliance: Meets current RoHS directives for environmentally conscious designs.
