• Temperature and Endurance – Operating temperature range from −55°C to 105°C with endurance specified as 2000 hours at 105°C under rated voltage conditions.
• Physical & Mounting – Radial lead can, case size φ10 × 12.5 mm (L: 12.5 mm × D: 10 mm), lead spacing 5.0 mm (±0.5 mm), available in bulk or bag packing.
• Leakage and Dissipation – Specified leakage current of 792 µA and tanδ (DF) of 0.08 at 20°C/120 Hz for predictable loss performance.

Typical Applications

• Power supply decoupling – Low ESR and high ripple capability make the RNS1C331MDN1 suitable for smoothing and decoupling on power rails in embedded and industrial systems.
• DC–DC converter output filtering – High-frequency ripple handling (5.5 A at 300 kHz) supports output filtering for switching regulators and point-of-load converters.
• General-purpose electronics – Compact radial package and wide temperature range support use in a variety of consumer and industrial designs that require reliable bulk capacitance.
• Bypass and hold-up circuits – 330 µF capacitance combined with solid polymer characteristics provides charge buffering and transient response where space is limited.

Unique Advantages

• Measurable high-frequency performance – ESR specified at 10 mΩ (20°C/100 kHz) supports predictable high-frequency behavior for design validation.
• Strong ripple current handling – 5.5 A at 300 kHz and 550 mA at 120 Hz let designers address both switching and mains-related ripple in one part.
• Wide operating temperature – Rated for −55°C to 105°C enabling use across harsh and variable environments.
• Long endurance at elevated temperature – 2000 hours at 105°C under rated voltage for durability in thermally demanding applications.
• Compact radial footprint – φ10 × 12.5 mm can with 5.0 mm lead spacing offers a small, through-hole form factor for legacy and serviceable PCB designs.
• Predictable leakage and dissipation – Specified leakage current and tanδ values support reliable power-loss and standby calculations.
