RS60E391MCN1

The RS60E391MCN1 is a Nichicon RS6 series conductive polymer aluminum solid electrolytic capacitor in a radial-lead can. It provides 390 µF capacitance at a 2.5 V rating in a miniature φ6.3 × 5 mm package with 2.5 mm lead spacing.

Designed for general-purpose electronic designs that require high capacitance, low ESR and high ripple handling in a compact radial-lead form factor, the device delivers measurable performance across wide frequency and temperature ranges while meeting RoHS requirements.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with ±20% tolerance and a 2.5 V rated voltage for bulk energy storage in compact spaces.
• Low ESR — 12 mΩ ESR measured at 20°C / 100 kHz, enabling reduced loss and improved efficiency in high-frequency circuits.
• High Ripple Current Capability — Rated ripple current of 350 mA at 120 Hz and 3.5 A at 300 kHz (105°C), supporting both low- and high-frequency power applications.
• Thermal and Lifetime Performance — Operating temperature range −55°C to 105°C with a rated load life of 2000 hours at 105°C.
• Package & Mounting — Radial lead mounting in a φ6.3 × 5 mm can with 2.5 mm lead spacing (±0.5 mm), supplied in bulk (no terminal forming) or bag packing.
• Leakage and Reliability — Leakage current specified at 500 µA (measured after 2 minutes’ application of rated voltage at 20°C), with endurance criteria defined for capacitance, tan δ and ESR after life test.
• Environmental Compliance — RoHS compliant.

Typical Applications

• High-frequency power rails — Low ESR at 100 kHz and rated ripple current at 300 kHz make this capacitor suitable for decoupling and smoothing on high-frequency DC‑DC converter outputs.
• Bulk energy storage in compact boards — 390 µF in a φ6.3 × 5 mm can provides high capacitance where board space is constrained.
• General-purpose electronics — Built for a wide range of general-purpose circuits that require reliable capacitance across −55°C to 105°C.

Unique Advantages

• High capacitance in a miniature package: 390 µF in a φ6.3 × 5 mm can reduces board area for bulk energy storage.
• Low AC loss at high frequency: 12 mΩ ESR at 100 kHz lowers power dissipation in high-frequency applications.
• Wide ripple handling range: Specified ripple current for both 120 Hz (350 mA) and 300 kHz (3.5 A) supports diverse power-supply conditions.
• Durability at elevated temperature: 2000 h life at 105°C provides predictable long-term performance for thermally demanding environments.
• Radial-lead convenience: Standard radial leads and common 2.5 mm spacing simplify through-hole assembly and prototyping.
• Regulatory readiness: RoHS compliance supports use in regions with restricted substance requirements.
