RS80E331MCN1

The RS80E331MCN1 is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial-lead can (φ6.3×8 mm) offering 330 µF capacitance at a 2.5 V rating. Engineered for general-purpose electronic applications, it combines low ESR/ESL and high ripple-current capability in a compact footprint.

Key value propositions include very low ESR (7 mΩ @ 20°C/100 kHz), strong high-frequency ripple performance (5.6 A rated ripple at 40°C/100 kHz), and a wide operating temperature range from −55°C to +105°C with a 2000 hour endurance at 105°C.

Key Features

• Core Technology — Conductive polymer aluminum solid electrolyte for improved conductivity and stability compared with conventional electrolytes.
• Electrical Performance — 330 µF capacitance with ±20% tolerance; tanδ ≤ 0.10 (20°C, 120 Hz); leakage current specified at 500 µA (measured at 20°C after 2 minutes).
• Low ESR / High Ripple — ESR of 7 mΩ at 20°C/100 kHz and rated ripple current of 5.6 A (40°C/100 kHz), with frequency coefficients that deliver full ripple rating at 100 kHz and 300 kHz.
• Mechanical / Packaging — Radial lead can, size φ6.3×8 mm, lead spacing 2.5 mm (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Temperature & Endurance — Operating range −55°C to +105°C and load life endurance of 2000 hours at 105°C (rated voltage).
• Compliance — RoHS compliant; radial lead type supports lead-free flow soldering conditions as noted in the series documentation.

Typical Applications

• General-purpose electronic circuits — Use where a compact 2.5 V, 330 µF polymer capacitor is required for decoupling or bulk energy storage in low-voltage designs.
• High-frequency ripple suppression — Suited to circuits that demand low ESR and rated ripple handling at 100–300 kHz.
• Space-constrained assemblies — Low-profile φ6.3×8 mm package for designs where board height and compact layout are priorities.

Unique Advantages

• Very low ESR — 7 mΩ at 20°C/100 kHz reduces voltage drop and heat generation under AC ripple, improving circuit efficiency and stability.
• High-frequency ripple capability — 5.6 A rated ripple at 40°C/100 kHz with frequency coefficients that maintain rating at 300 kHz, enabling reliable performance in high-frequency power domains.
• Compact, low-profile package — φ6.3×8 mm radial can fits tight layouts without sacrificing capacitance or ripple handling.
• Wide temperature range and proven endurance — −55°C to +105°C operation and 2000 h life at 105°C support robust long-term operation in demanding environments.
• Manufacturing-friendly lead form — Radial lead format and compatibility with lead-free flow soldering conditions simplify assembly processes.
• RoHS compliant — Meets applicable RoHS requirements for material compliance.
