RPS1H470MCN1GS

The RPS1H470MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package. With 47 µF capacitance at 50 V rating, low ESR and high ripple capability, it is intended for general purpose PCB-level power decoupling and energy storage in electronic designs.

Designed for demanding thermal environments, the device supports operation from −55°C to +105°C and a rated endurance of 2000 hours at 105°C, making it suitable for long-life commercial and industrial applications that require reliable SMD capacitance with low loss.

Key Features

• Conductive polymer aluminum construction — Solid electrolytic design for stable capacitance and controlled leakage current (470 µA at 20°C after 2 minutes).
• Capacitance and tolerance — 47 µF with ±20% tolerance measured at 120 Hz, 20°C.
• Voltage rating — 50 V rated voltage suitable for medium-voltage power rails.
• Low dissipation factor — tanδ 0.15 (20°C, 120 Hz) for reduced loss in AC conditions.
• Low ESR and high ripple handling — ESR of 26 mΩ at 20°C/100 kHz and ripple current capability of 230 mA at 120 Hz and 2.3 A at 300 kHz for robust high-frequency performance.
• Wide operating temperature and endurance — Rated for −55°C to +105°C with a life specification of 2000 hours at 105°C.
• Surface-mount radial can package — Compact φ8 × 11.7 mm can for board-level integration; supplied in embossed carrier taping with moisture-proof packing for assembly reliability.
• RoHS compliant and lead-free reflow compatible — Conforms to RoHS requirements and meets lead-free reflow soldering condition at a 260°C peak.

Typical Applications

• General purpose electronics — Provides bulk capacitance and decoupling where a 47 µF, 50 V SMD solution is required.
• Power rail filtering — Low ESR and high ripple current capability support filtering and smoothing of intermediate power rails at high frequency.
• Industrial and commercial assemblies — Suitable for designs requiring operation across −55°C to +105°C and long endurance at elevated temperature.

Unique Advantages

• Low ESR for high-frequency performance: 26 mΩ specified at 100 kHz reduces loss and improves ripple handling in switching power applications.
• High ripple current capability: Rated for 230 mA at 120 Hz and 2.3 A at 300 kHz, enabling reliable operation under AC-loading conditions.
• Thermal endurance: 2000 hours at 105°C provides predictable lifetime behavior in thermally demanding designs.
• Compact SMD can format: φ8 × 11.7 mm radial can gives a small board footprint with carrier tape packaging for automated assembly.
• Controlled leakage and loss: Leakage current of 470 µA and tanδ 0.15 (20°C, 120 Hz) support stable performance in steady-state and AC environments.
• RoHS compliant and reflow-capable: Meets RoHS and lead-free reflow soldering at 260°C, simplifying assembly process compliance.
