RPA1C390MCN1GS

The RPA1C390MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RPA series, supplied in a compact surface-mount radial can (φ6.3×5.7 mm). It delivers a nominal 39 µF capacitance at a 16 V rated voltage with a ±20% tolerance.

Designed for general-purpose electronic designs, the part combines low ESR, measurable high-frequency ripple capability and a wide operating temperature range to support compact, surface-mount power and decoupling applications. It is shipped in embossed carrier taping with moisture-proof packing and is RoHS compliant.

Key Features

• Conductive polymer construction — Solid electrolyte technology for stable performance and predictable characteristics.
• Capacitance and voltage — 39 µF nominal capacitance with a 16 V rated voltage and tolerance of −20% to +20%.
• Low ESR — ESR specified at 24 mΩ measured at 20°C/100 kHz, supporting low-loss operation at high frequencies.
• High ripple capability — Low-frequency ripple current of 250 mA (120 Hz) and high-frequency ripple current up to 2.5 A (300 kHz), with frequency coefficients provided in the series datasheet.
• Electrical leakage and dissipation — Leakage current specified at 124 µA and tangent of loss angle (tan δ) of 0.1 at 20°C/120 Hz.
• Temperature and endurance — Operating range from −55°C to +105°C and rated life/endurance of 2000 hours at 105°C.
• Compact SMD package — Case size φ6.3×5.7 mm (L×D) in a radial can SMD format; recommended land size 6.6×6.6 mm for surface mounting.
• Packaging and compliance — Supplied in embossed carrier taping with moisture-proof packing; RoHS compliant.

Typical Applications

• General purpose electronics — For surface-mount designs that require a 39 µF, 16 V conductive polymer capacitor with controlled ESR and ripple handling.
• Surface-mount power modules — Suitable where low ESR (24 mΩ at 100 kHz) and high-frequency ripple capability (2.5 A at 300 kHz) are needed in a compact footprint.
• Compact electronics and modules — Fits space-constrained SMD assemblies thanks to its φ6.3×5.7 mm package and embossed carrier taping for automated placement.

Unique Advantages
