RHA1C391MCN1GS

The RHA1C391MCN1GS is a Nichicon RHA series conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount radial can (φ8×8.7 mm). It delivers 390 µF capacitance at 16 V with a low ESR construction and series-defined high ripple current capability.

Designed for general-purpose electronic designs, the device targets applications that require high capacitance density, low equivalent series resistance and reliable operation across a wide temperature range (−55 °C to 105 °C). It is supplied in embossed carrier taping with moisture-proof packing for automated assembly.

Key Features

• Conductive polymer aluminum construction — Solid electrolyte technology provides low ESR and high capacitance in a compact SMD can.
• Capacitance and tolerance — 390 µF nominal with ±20% tolerance at 120 Hz, 20 °C.
• Rated voltage — 16 V DC rating for a wide range of general-purpose power applications.
• Low dissipation factor — tanδ = 0.12 (measured at 20 °C, 120 Hz) for controlled loss characteristics.
• Low ESR — ESR = 16 mΩ measured at 20 °C / 100 kHz, supporting improved high-frequency performance.
• High ripple current capability — 400 mA at 120 Hz (low frequency) and 4 A at 300 kHz (high frequency), with frequency coefficient data provided by the series.
• Leakage current — 1248 µA (measured after 2 minutes at 20 °C per product data).
• Endurance — Rated load life of 2000 hours at 105 °C per product specifications.
• Temperature range — −55 °C to 105 °C for broad environmental tolerance.
• Compact SMD package — Case size φ8 × 8.7 mm (L × D), surface-mount radial can; surface-mount land size L: 8.3 × W: 8.3 mm.
• Assembly compatibility — Series supports lead-free reflow soldering conditions with 260 °C peak.
• Packaging and compliance — Embossed carrier taping with moisture-proof packing; RoHS compliant and in mass production.

Typical Applications

• General-purpose power circuits — Suited for general-purpose designs that require stable bulk capacitance and low ESR in surface-mount form.
• High-frequency ripple management — The low ESR and specified ripple current ratings support circuits with significant high-frequency ripple demands.
• Compact electronic assemblies — Small φ8 can size enables higher capacitance in compact PCB layouts while remaining compatible with automated SMD assembly.

Unique Advantages

• Low ESR for high-frequency performance: 16 mΩ at 100 kHz reduces losses and supports effective filtering at elevated frequencies.
• High ripple-current handling: Up to 4 A at 300 kHz (series-rated) helps manage AC stress in demanding power stages.
• Robust thermal endurance: Rated for 2000 hours at 105 °C, providing predictable life characteristics in high-temperature environments.
• Compact SMD package: φ8×8.7 mm can offers a high-capacitance option for space-constrained PCB designs.
• Assembly-ready packaging: Supplied in embossed carrier tape with moisture-proof packing and compatible with 260 °C lead-free reflow profiles.
• Regulatory compliance: RoHS compliant to support environmentally restricted designs.
