RSL0E331MCN1GB

The RSL0E331MCN1GB is a conductive polymer aluminum solid electrolytic capacitor in a low-profile surface-mount radial can (φ6.3) package. It combines high capacitance with low ESR and high ripple-current capability for demanding general-purpose power applications.

Designed for PCB assembly with lead-free reflow compatibility to a 260°C peak, the part supports elevated-temperature operation and long load life for reliable performance in compact power designs.

Key Features

• Capacitance & Voltage: 330 µF rated at 2.5 V with ±20% tolerance, providing bulk capacitance in a compact SMD package.
• Low ESR: 16 mΩ ESR measured at 100 kHz, 20°C, enabling improved voltage stability and reduced losses in high-frequency circuits.
• High Ripple Current: Rated ripple currents of 350 mA at 120 Hz and 3.5 A at 300 kHz, supporting high AC stress on power rails.
• Compact Low-Profile Package: Case size φ6.3×4.2 mm (L: 4.2 × D: 6.3 mm) with surface-mount land size 6.5 × 6.5 mm for space-constrained boards.
• Wide Operating Temperature: Specified for −55°C to +105°C operation with a load life of 2000 hours at 105°C, for sustained performance under elevated temperature stress.
• Soldering & Compliance: SMD type compatible with lead-free reflow soldering conditions (260°C peak) and compliant with RoHS (2011/65/EU, (EU)2015/863).
• Leakage Current: Typical leakage current spec of 412 µA after 2 minutes at 20°C for the 330 µF, 2.5 V variant, supporting predictable bias behavior.

Typical Applications

• Power supply bulk smoothing: Use on low-voltage power rails where 330 µF bulk capacitance, low ESR, and high ripple capability improve voltage stability.
• DC–DC converter output filtering: Supports high-frequency ripple currents and low ESR to reduce output voltage ripple in compact converters.
• Board-level energy storage: Compact SMD radial can provides bulk energy in constrained layouts while withstanding elevated operating temperatures.

Unique Advantages

• High capacitance in a compact footprint: 330 µF in a φ6.3×4.2 mm case delivers substantial bulk capacitance for space-limited designs.
• Low ESR for efficiency: 16 mΩ ESR at 100 kHz reduces conduction losses and improves transient response when paired with switching power stages.
• Designed for high ripple environments: Rated ripple currents up to 3.5 A at 300 kHz address heavy AC stress on power rails.
• Thermal endurance: 2000-hour load life at 105°C offers extended reliability for sustained high-temperature operation.
• Manufacturing-ready: SMD construction with lead-free reflow compatibility (260°C peak) streamlines integration into modern assembly processes.
• Regulatory compliance: RoHS compliance provides assurance for global electronics manufacturing requirements.
