RSA0E331MCN1GS

The RSA0E331MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in an SMD radial can (φ6.3×5.7 mm) offering 330 µF capacitance at a 2.5 V rating. Designed for general-purpose surface-mount applications, it delivers low ESR and high ripple-current capability in a compact footprint.

Its combination of low ESR (14 mΩ at 20°C/100 kHz), high-frequency ripple performance, and a −55°C to 105°C operating range make it suitable where stable decoupling and bulk capacitance are required in small form factors.

Key Features

• Capacitance and Voltage — 330 µF rated capacitance at 2.5 V with tolerance −20% to +20% (measured at 120 Hz, 20°C).
• Low ESR — 14 mΩ ESR specified at 20°C/100 kHz, supporting efficient power delivery and reduced losses.
• High Ripple Current — Rated ripple current of 316 mA at 120 Hz and 3.16 A at 300 kHz (ESR and frequency measurement conditions per datasheet).
• Loss Angle (tan δ) — tan δ of 0.12 (measured at 20°C, 120 Hz), indicating low dielectric loss for stable performance.
• Leakage Current — 700 µA (measured after 2 minutes at 25°C), suitable for many general-purpose power applications.
• Temperature and Endurance — Rated for −55°C to 105°C with a load life of 2000 hours at 105°C under rated voltage conditions.
• Compact SMD Package — φ6.3×5.7 mm case (surface-mount radial can) with recommended land size 6.5 × 6.5 mm for PCB assembly.
• Assembly and Packaging — SMD type with lead-free reflow soldering condition (260°C peak) and supplied in embossed carrier taping / moisture-proof packing; product is in mass production.
• RoHS Compliant — Meets RoHS directive requirements as specified in the product datasheet.

Typical Applications

• General Purpose SMD Power Designs — 330 µF at 2.5 V in a compact SMD can for general-purpose board-level energy storage and smoothing where a low-ESR part is required.
• High Ripple Current Circuits — Suitable for circuits that require elevated ripple handling due to its rated ripple currents up to 3.16 A (300 kHz).
• Temperature-Variable Environments — Use in designs that need operation from −55°C to 105°C and a proven 2000-hour endurance at 105°C.
• Automated Assembly Processes — Supplied in embossed carrier taping and qualified for lead-free 260°C peak reflow soldering for surface-mount manufacturing.

Unique Advantages

• Low ESR for Improved Efficiency — 14 mΩ at 100 kHz reduces I²R losses and helps maintain voltage stability under load.
• Strong High-Frequency Performance — Ripple current rating of 3.16 A at 300 kHz supports demanding high-frequency applications.
• Wide Temperature Endurance — −55°C to 105°C range with 2000-hour life at 105°C provides predictable aging and reliability under elevated temperature stress.
• Compact Footprint — φ6.3×5.7 mm case enables high-capacitance placement in space-constrained SMD designs.
• Assembly-Ready Packaging — Embossed carrier tape and moisture-proof packing facilitate automated pick-and-place and reflow processes.
• Standards Compliance — Constructed with lead-free reflow compatibility and RoHS-compliant materials per datasheet statements.
