RF80E331MDN1

The RF80E331MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial lead can (φ5×8 mm) offering 330 µF capacitance at a 2.5 V rating. Designed for general-purpose electronic use, it provides low ESR and high ripple-current capability for demanding power-decoupling and bulk-filtering applications.

Key value comes from low ESR (7 mΩ at 20°C/100 kHz), high-frequency ripple handling (4.2 A at 300 kHz), wide operating temperature (−55°C to 105°C) and a rated life of 2000 hours at 105°C—attributes that help maintain stable performance in compact assemblies.

Key Features

• Conductive polymer construction Solid electrolytic design for stable electrical characteristics and low equivalent series resistance.
• Capacitance & tolerance 330 µF with ±20% tolerance at 120 Hz, 20°C, suitable for energy storage and decoupling roles.
• Low ESR & high ripple capability ESR of 7 mΩ (20°C/100 kHz) and rated ripple current up to 4.2 A at 300 kHz (420 mA at 120 Hz) for effective high-frequency and low-frequency ripple handling.
• Compact, low-profile package φ5×8 mm can with 2.0 mm lead spacing (±0.5 mm) and radial lead mounting for space-constrained PCB layouts.
• Wide temperature and endurance Operating range −55°C to 105°C with a load life of 2000 hours at 105°C under rated voltage.
• Leakage and dissipation Leakage current specified at 500 µA and tan δ of 0.10 (measured at 20°C, 120 Hz), supporting predictable loss and self-heating behavior.
• Packaging & compliance Available in bulk (no terminal forming) / bag packing and RoHS compliant; product is in mass production.

Typical Applications

• Power rail decoupling Low ESR and high ripple capacity make the RF80E331MDN1 well suited for local decoupling on DC power rails in compact electronics.
• Switching regulator output filtering High-frequency ripple current rating and low ESR support effective filtering at regulator outputs, especially where space is limited.
• Bulk energy storage in compact boards 330 µF capacitance in a φ5×8 mm can provides bulk capacitance in tight layouts requiring radial lead components.

Unique Advantages

• High ripple tolerance: With 4.2 A rated ripple at 300 kHz and 420 mA at 120 Hz, the capacitor handles both high- and low-frequency ripple without excessive heating.
• Low ESR for stable performance: 7 mΩ ESR (20°C/100 kHz) reduces voltage drop and improves transient response in power circuits.
• Small footprint, low profile: φ5×8 mm size and radial lead format deliver significant capacitance in a compact can for space-constrained designs.
• Robust thermal endurance: Rated for −55°C to 105°C with a 2000-hour life at 105°C, supporting long-term operation under elevated temperature conditions.
• Predictable leakage and dissipation: 500 µA leakage current and tan δ of 0.10 (20°C, 120 Hz) enable designers to model standby loss and heating accurately.
• Ready for production: RoHS compliant and listed as mass production, simplifying procurement and qualification for volume builds.
