RNE0J331MDS1

The RNE0J331MDS1 is a conductive polymer aluminum solid electrolytic capacitor offering 330 µF capacitance at a 6.3 V rating. It is a radial lead, polarized capacitor designed for general-purpose circuit use where high capacitance, low ESR and strong ripple-current capability are required.

Key value propositions include low ESR (10 mΩ at 100 kHz), high ripple-current handling (3.7 A at 300 kHz), and extended load-life ratings at elevated temperature (2000 / 5000 hours at 105°C), making it suitable for compact, high-performance power applications.

Key Features

• Conductive polymer aluminum construction — Solid electrolyte design for stable electrical performance with high capacitance density.
• High capacitance — 330 µF nominal capacitance for compact bulk energy storage and decoupling in space-constrained circuits.
• Low ESR — 10 mΩ (measured at 100 kHz, 20°C) to reduce power loss and improve efficiency in high-frequency applications.
• High ripple-current capability — Rated ripple currents of 370 mA at 120 Hz and 3.7 A at 300 kHz for demanding power-conditioning tasks.
• Wide temperature range and endurance — Operating range −55°C to +105°C with load life tested to 2000 / 5000 hours at 105°C.
• Radial lead, through-hole package — Compact φ5×8 mm can (L: 8 × D: 5 mm) with 2.0 mm lead spacing for easy PCB mounting in through-hole assemblies.
• Compliance and solder compatibility — Lead-free flow soldering condition correspondence and RoHS compliance (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and high-frequency smoothing in general-purpose power circuits where low ESR and high ripple capability improve regulation.
• DC‑DC converter output stages — Compact 330 µF capacitance and low ESR help manage output ripple and transient response in space-constrained converter designs.
• High-frequency power conditioning — Rated ripple current at 300 kHz (3.7 A) supports applications with significant high-frequency switching content.

Unique Advantages

• High energy density in a small can — 330 µF in a φ5×8 mm package enables reduced board area for equivalent capacitance compared to larger electrolytic options.
• Reduced heating and loss — Low ESR (10 mΩ at 100 kHz) minimizes power dissipation under ripple and reduces thermal stress on surrounding components.
• Robust ripple-current handling — High-frequency ripple rating (3.7 A at 300 kHz) supports long-term performance in switching environments.
• Designed for elevated-temperature endurance — Load life performance of 2000 / 5000 hours at 105°C provides predictable aging characteristics for thermal-stressed designs.
• Through-hole radial format — Familiar radial lead package simplifies assembly and provides mechanical robustness for board-level power components.
• Regulatory and assembly readiness — Lead-free solder compatibility and RoHS compliance support modern manufacturing and environmental requirements.
