RS80J331MCN1

The RS80J331MCN1 is a conductive-polymer aluminum electrolytic capacitor in a low-profile, radial-lead can. It delivers 330 µF capacitance at a 6.3 V rating with a compact 6.3 mm diameter and 8 mm length, designed for space-constrained power circuits.

With low ESR/ESL characteristics and high ripple-current capability, this part targets general-purpose power applications where low loss, high-frequency performance and a small footprint are required. It is RoHS‑compliant and compatible with lead‑free flow soldering conditions.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 6.3 V with ±20% tolerance for bulk energy storage and decoupling.
• Low ESR / Low ESL — Engineered for low equivalent series resistance (8 mΩ at 100 kHz) and low ESL to minimize loss and improve high‑frequency response.
• High Ripple Current — Supports 500 mA at 120 Hz (low frequency) and 5 A at 300 kHz (high frequency) for demanding ripple and switching environments.
• Compact, Low‑Profile Package — Radial can construction with φ6.3 × 8 mm size and 2.5 mm lead spacing for tight board layouts.
• Wide Operating Temperature Range — Rated for −55 °C to +105 °C to cover typical industrial and consumer electronic operating environments.
• Durability & Life — Specified load life of 2000 hours at 105 °C to support sustained thermal and electrical stress.
• Manufacturing Compatibility & Compliance — Radial lead type with lead‑free flow soldering condition correspondence and RoHS directive compliance (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supply Filtering — Low ESR and high ripple capability make the RS80J331MCN1 suitable for output filtering and smoothing in compact switching supplies.
• DC‑DC Converter Decoupling — Small footprint and strong high‑frequency performance support decoupling at converter outputs and intermediate stages.
• Compact Consumer and Industrial Electronics — Low profile and radial can packaging fit tight PCB spaces for general-purpose energy storage and transient suppression.

Unique Advantages

• Performance in Small Form Factor — 330 µF in a φ6.3 × 8 mm can provides significant capacitance where board space is limited.
• Improved Efficiency at High Frequency — 8 mΩ ESR at 100 kHz and low ESL reduce conduction losses and heat generation in switching applications.
• Handles High Ripple Currents — Rated ripple currents up to 5 A at 300 kHz enable use directly on high‑speed power rails and converters.
• Wide Temperature Range and Known Lifetime — −55 °C to +105 °C rating with 2000 h life at 105 °C supports reliable operation across common thermal conditions.
• Assembly‑Friendly Packaging — Radial lead format with lead‑free flow soldering correspondence eases through‑hole assembly in lead‑free production lines.
• Regulatory Compliance — RoHS conformity reduces material compliance risk in global product designs.
