RSA0E391MCN1GS

The RSA0E391MCN1GS is a Nichicon conductive polymer aluminum solid electrolyte capacitor in a surface-mount radial can package. It delivers 390 µF at a 2.5 V rating with low ESR and high ripple-current capability, intended for general-purpose electronic applications.

Key value propositions include low equivalent series resistance (14 mΩ at 20°C/100 kHz), high-frequency ripple handling (3.16 A / 3160 mA), a wide operating temperature range (−55°C to 105°C) and a rated load life of 2000 hours at 105°C—packaged for automated assembly with embossed carrier taping and moisture-proof packing.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance with ±20% tolerance rated at 2.5 V for stable bulk energy storage in small SMD footprints.
• Low ESR & High Ripple Current — ESR of 14 mΩ measured at 20°C/100 kHz and high-frequency ripple current rated at 3.16 A (3160 mA), enabling better AC performance in power circuits.
• Dielectric Loss (tan δ) — tan δ of 0.12 at 120 Hz, 20°C, supporting predictable impedance and loss behavior.
• Leakage Current — Specified leakage current of 700 µA (after 2 minutes at rated voltage, 25°C), ensuring known standby loss characteristics.
• Reliability & Endurance — Load life specified as 2000 hours at 105°C under rated voltage; ESR and tan δ limits specified for end-of-life criteria.
• Temperature Range — Rated for operation from −55°C to 105°C to support elevated-temperature deployments within its endurance rating.
• Compact SMD Package — Case size φ6.3 × 5.7 mm (L × D: 5.7 × 6.3 mm) in a radial can SMD format with recommended land size 6.5 × 6.5 mm.
• Assembly-Ready Packaging — Supplied in embossed carrier taping with moisture-proof packing for surface-mount production lines.
• Regulatory — RoHS compliant.

Typical Applications

• General Purpose Electronics — Suited for designs specifying a 390 µF, 2.5 V conductive polymer aluminum SMD capacitor for general-purpose power components.
• Space-Constrained SMD Designs — The φ6.3 × 5.7 mm SMD radial can fits compact board layouts where high capacitance density is required.
• Elevated-Temperature Applications — With a −55°C to 105°C operating range and 2000 h life at 105°C, it supports applications that require sustained operation at higher ambient temperatures.

Unique Advantages

• High AC Handling in a Small Footprint: 3.16 A (3160 mA) high-frequency ripple rating combined with 14 mΩ ESR provides strong ripple performance without large board area.
• Predictable Electrical Behavior: Specified tan δ (0.12) and defined leakage current (700 µA) enable reliable design margining and component selection.
• Endurance at Elevated Temperature: 2000 hours rated life at 105°C offers a clear, specified reliability metric for thermal stress planning.
• Surface-Mount Ready: Embossed carrier taping and moisture-proof packing simplify automated assembly and inventory handling.
• Regulatory Compliance: RoHS-compliant construction supports deployments requiring restricted-substance conformity.
• Mass Production Availability: Product status listed as mass production for predictable supply and procurement planning.
