RF80G331MDN1

The RF80G331MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a compact radial-can package (φ5×8 mm). It delivers 330 µF at 4 V with low ESR and high ripple capability for general-purpose power applications.

Designed for compact, high-ripple environments, this RoHS-compliant part offers a low-profile footprint, wide temperature range (–55°C to 105°C), and a rated life of 2000 hours at 105°C, making it suitable where low impedance and thermal endurance are required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 4 V and tolerance ±20% (120 Hz, 20°C).
• Low ESR — ESR of 8 mΩ measured at 20°C/100 kHz, supporting low-loss performance in high-frequency power paths.
• High Ripple Current — Rated ripple current up to 4.0 A (high-frequency condition) and 400 mA at 120 Hz, enabling robust handling of switching currents.
• Small, Low-Profile Package — φ5×8 mm radial can with 2.0 mm lead spacing (±0.5 mm), suitable for dense board layouts and point-of-load placement.
• Thermal Endurance — Specified load life of 2000 hours at 105°C under rated voltage conditions for sustained high-temperature operation.
• Leakage & Loss Characteristics — Leakage current specified at 500 µA (after 2 minutes at 25°C); tangent of loss angle (tan δ) specified at 0.10 (120 Hz, 20°C).
• RoHS Compliant & Production Ready — Lead-free solder flow compatibility for radial lead type and mass production status.

Typical Applications

• Switching regulator decoupling — Low ESR and high ripple rating make the RF80G331MDN1 well suited for output filtering and decoupling in DC–DC converters.
• Point-of-load filtering — Compact φ5×8 mm package and strong ripple capability support tight placement at point-of-load locations.
• Portable and compact electronics — Low profile and small diameter provide bulk capacitance in space-constrained designs operating across –55°C to 105°C.

Unique Advantages

• Improved power integrity: Low ESR (8 mΩ at 100 kHz) reduces voltage ripple and switching losses in power rails.
• High ripple tolerance: Up to 4.0 A rated ripple current at high frequency helps manage transient and switching currents without excessive heating.
• Thermal reliability: 2000-hour endurance at 105°C provides predictable lifetime performance under elevated-temperature stress.
• Space-efficient design: φ5×8 mm can with 2.0 mm lead spacing delivers high capacitance in a compact, low-profile form factor.
• Measured performance conditions: ESR and tan δ values are specified at 20°C and high-frequency measurement points to aid accurate design margining.
