RNS0J331MDN1

The RNS0J331MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can package. It delivers 330 µF capacitance at a 6.3 V rating with a compact φ10 × 12.5 mm footprint and 5.0 mm lead spacing (±0.5 mm).

Designed for general-purpose electronic applications, the RNS0J331MDN1 combines low ESR, high ripple handling and a wide operating temperature range to support power decoupling and energy-buffering needs in densely packaged circuits.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C and a 6.3 V rated voltage (surge 7.2 V).
• Conductive Polymer Construction — Solid conductive polymer aluminum electrolyte for stable electrical performance versus liquid electrolytes.
• Low ESR — 10 mΩ ESR measured at 20°C/100 kHz, enabling efficient high-frequency performance and reduced dissipation.
• High Ripple Current Capability — Rated ripple current 5500 mArms at 105°C/100 kHz; frequency coefficients yield 550 mA at 120 Hz (0.10 coefficient) and full rating at high frequencies (100–300 kHz coefficients 1.00).
• Leakage Current — Specified leakage current of 311 µA (measured at 25°C after 2 minutes).
• Endurance & Temperature Range — 2000 hours at 105°C under rated voltage; operating temperature range −55°C to +105°C. Endurance limits: capacitance change within ±20%, tan δ and ESR ≤150% of initial specified values, leakage current within initial specified value after test.
• Package & Mounting — Radial lead can, polarized electrolyte with dimensions φ10 × 12.5 mm and lead spacing P = 5.0 mm (±0.5 mm). Supplied in bulk / bag packing with no terminal forming.

Typical Applications

• General-purpose electronics — Local energy storage and decoupling where 330 µF at 6.3 V with low ESR and high ripple capability are required.
• Power regulation circuits — Smoothing and ripple suppression in DC-DC converters and linear regulators operating within the −55°C to +105°C range.
• High-frequency power networks — High ripple current rating at 100 kHz–300 kHz supports applications with significant HF switching activity.

Unique Advantages

• High ripple handling: Rated 5.5 A (5500 mArms) at 105°C/100 kHz, enabling robust performance in switching-power environments.
• Low ESR for efficient delivery: 10 mΩ ESR at 20°C/100 kHz reduces loss and improves transient response in power-sensitive circuits.
• Wide temperature endurance: −55°C to +105°C operation with 2000 h endurance at 105°C supports long-term reliability under elevated temperature stress.
• Compact radial can footprint: φ10 × 12.5 mm package with standard 5.0 mm lead spacing simplifies layout for through-hole assemblies.
• Solid polymer electrolyte: Conductive polymer construction provides stable electrical characteristics and controlled leakage behavior.
