RNU1H470MDN1

The RNU1H470MDN1 is a radial-lead conductive polymer aluminum solid electrolytic capacitor with 47 µF capacitance and a 50 V rated voltage. Designed for general-purpose through-hole applications, it delivers low ESR and high ripple-current capability in a compact φ10×12.5 mm can.

Key value propositions include low equivalent series resistance (24 mΩ at 20°C/100 kHz), high-frequency ripple handling (2.7 A at 300 kHz), and robust thermal endurance (2000 hours at 105°C), making it suitable for designs that require stable decoupling and power-conditioning performance across −55°C to 105°C.

Key Features

• Capacitance and Voltage — 47 µF capacitance with a 50 V rated voltage and ±20% tolerance for predictable energy storage and tolerance-aware design.
• Low ESR — 24 mΩ ESR measured at 20°C/100 kHz, enabling improved high-frequency performance and reduced dissipation in power rails.
• High Ripple Current Capability — Low-frequency ripple current of 270 mA (120 Hz) and high-frequency ripple current of 2.7 A (300 kHz) to support both bulk and high-frequency decoupling needs.
• Thermal Endurance — Rated for 2000 hours at 105°C, with operating temperature range from −55°C to 105°C for demanding thermal environments.
• Leakage and Dissipation — Leakage current specified at 470 µA and tanδ (DF) of 0.12 at 20°C/120 Hz to aid in predictable leakage budgeting and loss calculations.
• Package and Mounting — Radial lead can (φ10×12.5 mm) with 5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for through-hole assembly and manual or wave/flow soldering processes.
• Regulatory — RoHS compliant.

Typical Applications

• Power-supply output filtering — Low ESR and 2.7 A high-frequency ripple rating help reduce output voltage ripple in switching regulators and DC–DC converters.
• Decoupling for high-frequency circuits — 24 mΩ ESR at 100 kHz and specified ripple current at 300 kHz provide effective high-frequency decoupling for analog and digital modules.
• General-purpose through-hole assemblies — Radial lead form factor and bulk/bag packaging make the part suitable for prototyping, repair, and production through-hole boards.
• Industrial electronics — Wide operating temperature range (−55°C to 105°C) and 2000-hour endurance at 105°C support thermal reliability requirements in industrial equipment.

Unique Advantages

• Measurable high-frequency performance: 24 mΩ ESR at 100 kHz and a 2.7 A ripple rating at 300 kHz enable designers to quantify expected loss and ripple suppression at switching frequencies.
• Thermally robust: Specified 2000 hours at 105°C provides an endurance metric for lifetime planning in thermally demanding applications.
• Compact through-hole package: φ10×12.5 mm can with 5 mm lead spacing delivers high capacitance in a small radial-lead footprint for space-constrained boards.
• Predictable leakage and dissipation: Leakage current (470 µA) and tanδ (0.12 at 20°C/120 Hz) give clear parameters for power-loss and standby-current calculations.
• Production-ready packaging: Available in bulk (no terminal forming) or bag packing to support manufacturing flows from prototyping to mass production.
• RoHS compliance: Meets RoHS directive requirements for environmentally regulated designs.
