RDS0G331MCNAHFGS

The RDS0G331MCNAHFGS is a conductive polymer aluminum solid electrolytic capacitor in an SMD can package, offering 330 µF capacitance at a 4 V rating. It is designed for compact assemblies that require high capacitance and robust performance across a wide temperature range.

Key attributes include low ESR at high frequency, high ripple-current capability, and a load life of 3000 hours at 125°C, making it suitable for designs where long-term thermal endurance and stable electrical performance are required.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 4 V with ±20% tolerance for predictable bulk energy storage.
• High-temperature Endurance — Rated operating temperature −55°C to +125°C with a specified load life of 3000 hours at 125°C.
• Low ESR — ESR of 18 mΩ measured at 100 kHz, 20°C, supporting efficient high-frequency performance.
• High Ripple Current — Rated ripple current is 105 mA at 120 Hz and 1.05 A at 300 kHz, enabling reliable AC stress handling in compact packages.
• SMD Can Package — Radial, can-style SMD package (L: 6.7 × D: 8 mm) with recommended land size L: 8.3 × W: 8.3 mm for surface-mount assembly.
• Reflow Compatibility — SMD type compatible with lead-free reflow peak temperature of 260°C for modern assembly processes.
• Polarized, Surface Mount — Polarized capacitor intended for surface-mount placement in PCB designs.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements.

Typical Applications

• Power delivery in compact electronics — Provides bulk capacitance and high ripple handling in space-constrained power modules and converters.
• High-temperature electronics — Suitable where components must maintain capacitance and ESR performance up to 125°C for extended periods.
• High-frequency filtering — Low ESR at 100 kHz and elevated ripple-current capability make it appropriate for decoupling and filtering in high-frequency circuits.

Unique Advantages

• Thermal longevity: A specified load life of 3000 hours at 125°C provides predictable end-of-life behavior for heat-exposed designs.
• High-frequency efficiency: Low ESR (18 mΩ at 100 kHz) and high ripple-current ratings reduce losses and improve thermal management in high-rate switching environments.
• Surface-mount convenience: Can-style SMD package supports automated assembly with lead-free reflow to 260°C.
• Compact energy density: 330 µF in an 8 × 6.7 mm package helps preserve board space while delivering substantial capacitance.
• Regulatory compliance: RoHS conformity simplifies selection for environmentally regulated products.
