RNU0J221MDS1

The RNU0J221MDS1 is a Nichicon RNU-series conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, rated 220 µF at 6.3 V. It delivers low ESR and high ripple-current capability in a compact φ6.3×10 mm package intended for general-purpose electronic designs.

Designed for applications requiring high capacitance density, low loss and robust temperature performance, this part offers a wide operating range (–55°C to 105°C), a 2000-hour endurance at 105°C, and RoHS compliance for regulated manufacturing environments.

Key Features

• Conductive Polymer Dielectric Solid polymer construction for low equivalent series resistance and stable performance.
• Low ESR ESR = 20 mΩ (measured at 20°C / 100 kHz), supporting efficient high-frequency decoupling and power delivery.
• High Ripple-Current Capability Rated ripple current up to 320 mA at 120 Hz (low frequency) and 3.2 A at 300 kHz (high frequency), enabling effective smoothing under dynamic loads.
• Electrical Characteristics Capacitance 220 µF with tolerance ±20% and tanδ = 0.08 (20°C, 120 Hz), providing predictable filtering behavior.
• Robust Temperature and Lifetime Operating range –55°C to 105°C and rated life/endurance of 2000 hours at 105°C under rated voltage.
• Compact Radial Package Case size φ6.3×10 mm with 2.5 mm lead spacing (±0.5 mm) for through-hole assemblies and tight PCB layouts.
• Manufacturing & Compliance Radial lead type with lead-free flow soldering condition correspondence and RoHS compliance.
• Leakage Current Specified leakage current of 277 µA (measured after application conditions), useful for power-rail budgeting.

Typical Applications

• Power Supply Filtering Bulk and high-frequency filtering on low-voltage rails where 220 µF capacitance and low ESR improve transient response.
• DC–DC Converter Output Decoupling and smoothing on converter outputs that require high ripple-current handling and compact radial components.
• Embedded and Consumer Electronics General-purpose energy storage and noise suppression in compact assemblies operating across –55°C to 105°C.

Unique Advantages

• Low ESR for Improved Efficiency: 20 mΩ ESR at 100 kHz reduces power loss and heating in high-frequency circuits.
• High-Frequency Ripple Handling: Rated 3.2 A ripple at 300 kHz supports demanding switching applications and fast transient loads.
• Compact, Through-Hole Form Factor: φ6.3×10 mm radial can with 2.5 mm lead spacing fits space-constrained boards while keeping assembly straightforward.
• Wide Temperature and Proven Endurance: –55°C to 105°C range and 2000-hour life at 105°C offer predictable behavior in thermally challenging environments.
• Manufacturing-Ready Packaging: Available in bulk or bag packing for flexible procurement and production workflows.
• Regulatory Compliance: RoHS-compliant construction supports regulatory requirements for electronic assemblies.
