RS80J331MDN1

The RS80J331MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial-can package (φ6.3×8 mm) designed for general-purpose board-level power applications. It delivers a combination of low ESR/ESL, high ripple-current capability and a compact footprint for space-constrained designs.

With a rated capacitance of 330 µF at 6.3 V, a wide operating temperature range (−55 °C to +105 °C) and RoHS compliance, this part is suited to applications that require reliable decoupling and smoothing with elevated ripple-handling and long-term endurance.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 6.3 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• Low ESR / Low ESL — ESR of 8 mΩ at 20 °C/100 kHz and design emphasis on low ESL for improved high-frequency performance.
• High Ripple Current — Rated ripple-current capability of 500 mA at 120 Hz (low frequency) and 5 A at 300 kHz (high frequency), enabling effective filtering under varying ripple conditions.
• Low-Profile, Compact Package — φ6.3×8 mm radial-can footprint (L: 8 × D: 6.3 mm) with 2.5 mm lead spacing (±0.5 mm) for compact PCB implementations.
• Wide Temperature & Endurance — Operating range −55 °C to +105 °C and rated life of 2000 hours at 105 °C.
• Electrical Characteristics — Tangent of loss angle (tan δ) of 0.10 (120 Hz, 20 °C) and leakage current specified at 519 µA (after 2 minutes, 20 °C).
• Mounting & Packaging — Radial lead mounting type; available in bulk (no terminal forming) or bag packing; polarized component.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General purpose board-level decoupling — Low ESR and compact φ6.3×8 mm package make this capacitor suitable for decoupling and bulk smoothing where board space is limited.
• Power-supply ripple suppression — High ripple-current capability (5 A at 300 kHz; 500 mA at 120 Hz) and low ESR (8 mΩ at 100 kHz) support filtering of high-frequency switching noise and ripple.
• Compact consumer and industrial electronics — Radial-lead mounting, small footprint (L: 8 × D: 6.3 mm) and −55 °C to +105 °C operating range accommodate compact, wide-temperature designs while maintaining RoHS compliance.

Unique Advantages

• Low-ESR performance: 8 mΩ at 20 °C/100 kHz reduces voltage drop and heating in high-frequency applications, improving power-stage stability.
• High ripple handling: Rated for 5 A at 300 kHz and 500 mA at 120 Hz, enabling effective suppression of both high-frequency switching ripple and lower-frequency mains-related ripple.
• Space-saving low profile: φ6.3×8 mm can package provides high capacitance in a compact envelope for tight-layout PCBs.
• Broad temperature and endurance: −55 °C to +105 °C operating range with 2000-hour life at 105 °C supports robust operation in demanding thermal environments.
• Radial-lead convenience: Through-hole radial leads with 2.5 mm spacing simplify mechanical mounting and prototyping while offering reliable soldering options.
• Regulatory readiness: RoHS compliance (2011/65/EU, (EU)2015/863) supports environmentally constrained product designs.
