RHA0J471MCN1GS

The RHA0J471MCN1GS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in an SMD radial can package. It delivers 470 µF capacitance at a 6.3 V rating and is designed for general-purpose applications that require low ESR, high ripple handling, and compact surface-mount form factors.

As a member of Nichicon’s RHA series, this part offers a combination of low loss (tanδ 0.12 at 20°C, 120 Hz), high-frequency capability (ESR 9 mΩ at 20°C / 100 kHz) and rated endurance (2000 hours at 105°C), making it suitable for power smoothing and decoupling in space-constrained designs.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance with a rated voltage of 6.3 V and tolerance of -20% to +20%.
• Conductive Polymer Construction: Solid electrolyte construction provides stable performance with a specified tanδ of 0.12 (20°C, 120 Hz).
• Low ESR: ESR specified at 9 mΩ (20°C / 100 kHz), supporting efficient high-frequency decoupling and reduced power loss.
• High Ripple Current Capability: Low-frequency ripple current of 450 mA (120 Hz) and high-frequency ripple current of 4.5 A (300 kHz), with frequency coefficients provided across 120 Hz–300 kHz.
• Thermal and Endurance Ratings: Operating temperature range of -55°C to +105°C with a rated load life of 2000 hours at 105°C.
• Compact SMD Can Package: φ8 × 6.7 mm case (radial, can - SMD) and surface-mount land size 8.3 × 8.3 mm for compact PCB layouts.
• Leakage & Reliability: Specified leakage current of 888 µA (measured after 2 minutes at 20°C) with ESR and tanδ endurance limits defined for life testing.
• Assembly-Ready Packaging: Supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow processes up to a 260°C peak temperature.
• RoHS Compliance: Conforms to RoHS requirements as specified in the product documentation.

Typical Applications

• General-purpose electronics: Bulk energy storage and decoupling where 470 µF capacitance and low ESR (9 mΩ) reduce voltage ripple on power rails.
• SMT power modules: Compact surface-mount can (φ8×6.7 mm) provides bulk capacitance in tightly packed DC-DC converters and regulator modules.
• High-frequency power filtering: High-frequency ripple current rating (4.5 A at 300 kHz) supports filtering and smoothing in high-switching-frequency designs.

Unique Advantages

• Low ESR for efficient power handling: 9 mΩ (20°C / 100 kHz) ESR minimizes I2R loss and improves high-frequency decoupling effectiveness.
• High ripple capability across frequencies: Rated ripple currents of 450 mA (120 Hz) and 4.5 A (300 kHz) enable use in both low- and high-frequency power networks.
• Robust thermal performance: Rated for -55°C to +105°C with a 2000-hour endurance at 105°C, supporting sustained operation in elevated-temperature environments.
• Compact SMD form factor: φ8 × 6.7 mm casing and standard land pattern simplify integration into dense PCB layouts while preserving bulk capacitance.
• Assembly-ready packaging and process support: Embossed carrier taping with moisture-proof packing and lead-free reflow compatibility (260°C peak) streamline automated assembly.
• Specification transparency: Key parameters such as tanδ (0.12 at 20°C/120 Hz), leakage current (888 µA), and frequency ripple coefficients are specified for engineering validation.
