RNU1C471MDNASQ

The RNU1C471MDNASQ is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can designed for general-purpose electronic power applications. It delivers 470 µF capacitance at a 16 V rating with low ESR and high ripple-current capability for demanding power-rail decoupling and smoothing tasks.

Targeted at designs that require reliable long-term performance across a wide temperature range, this radial-lead device combines a compact Φ10 can, 5 mm lead spacing, and production-ready packaging for straightforward through-hole assembly.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with ±20% tolerance and a 16 V rated voltage for general-purpose power storage and decoupling.
• Low ESR — 10 mΩ ESR measured at 20°C/100 kHz, reducing AC loss and improving high-frequency performance.
• High Ripple Current — Supports 610 mA at 120 Hz and up to 6.1 A at 300 kHz for robust ripple-handling in switching power stages.
• Long Endurance — 5000 hours load life at 105°C, providing sustained performance in elevated-temperature environments.
• Wide Operating Range — Specified for −55°C to +105°C operation to cover a broad range of industrial and commercial ambient conditions.
• Radial Lead Package — Through-hole radial can with 5 mm lead spacing (±0.5 mm) for easy PCB placement and manual or automated insertion.
• Manufacturing & Packaging — Supplied in bulk with no terminal forming and bag packing; part is in mass production.
• RoHS Compliant — Conforms to RoHS requirements for use in compliant assemblies.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling on DC power rails where low ESR and high ripple current are required.
• Switching power supplies — Input/output filtering in switching regulators benefiting from high-frequency ripple capability.
• Industrial and commercial electronics — Power reservoirs and transient suppression in equipment operating across −55°C to +105°C.

Unique Advantages

• Improved efficiency under AC load: Low 10 mΩ ESR at 100 kHz reduces dissipation and helps maintain converter efficiency.
• Handles high ripple stress: Up to 6.1 A at high frequency supports demanding switching environments and reduces the need for parallel capacitors.
• Extended high-temperature life: 5000-hour endurance at 105°C offers predictable longevity in elevated-temperature applications.
• Wide temperature capability: −55°C to +105°C operation enables use across a broad set of environmental conditions.
• Production-ready packaging: Bulk bag packing and no terminal forming simplify inventory and assembly flows for through-hole manufacturing.
• Regulatory compliance: RoHS conformity supports deployment in standards-driven product lines.
