RNU0G182MDN1

The RNU0G182MDN1 is a conductive polymer aluminum solid electrolytic capacitor in a radial-can package, offering 1.8 mF capacitance at a 4 V rating. Designed for general-purpose electronic designs, it provides high capacitance density with low equivalent series resistance and high ripple handling for power-related decoupling and energy-storage needs.

Packaged as a φ10×12.5 mm radial lead component with 5 mm lead spacing, the device is RoHS compliant and rated for operation from −55°C to 105°C with a rated life of 2000 hours at 105°C.

Key Features

• Conductive polymer solid electrolyte Provides high capacitance in a compact aluminum-can radial package (φ10×12.5 mm).
• High capacitance 1.8 mF (1800 µF) nominal capacitance for bulk energy storage and decoupling in low-voltage systems.
• Low ESR ESR of 7 mΩ measured at 20°C/100 kHz supports efficient high-frequency performance.
• High ripple current capability Rated ripple current: 610 mA at 120 Hz and 6.1 A at 300 kHz, enabling effective smoothing under both low- and high-frequency conditions.
• Electrical loss and leakage tanδ = 0.08 (20°C, 120 Hz) and leakage current 1440 µA (after 2 minutes at 20°C) for predictable AC and DC behaviour.
• Wide temperature and endurance Operating range −55°C to 105°C and endurance rating of 2000 hours at 105°C for elevated-temperature applications.
• Radial lead package and handling φ10×12.5 mm can, 5.0 mm lead spacing (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Regulatory RoHS compliant.

Typical Applications

• General-purpose power electronics — Suited for designs that require high capacitance and low ESR at low voltages for decoupling and energy storage.
• Power supply filtering — High ripple-current ratings at both low and high frequencies support smoothing and transient handling in DC power rails.
• Embedded systems and industrial controls — Compact radial-can form factor and extended temperature range support reliable service in space-constrained assemblies operating across −55°C to 105°C.

Unique Advantages

• High capacitance in a small footprint: 1.8 mF in a φ10×12.5 mm radial package reduces board area for bulk storage requirements.
• Excellent high-frequency performance: 7 mΩ ESR at 100 kHz and 6.1 A ripple capability at 300 kHz enables effective high-speed decoupling and noise suppression.
• Reliable elevated-temperature operation: Rated for 2000 hours at 105°C, providing predictable life under sustained thermal stress.
• Consistent AC characteristics: tanδ = 0.08 at 20°C/120 Hz supports stable loss behavior in AC conditions.
• Through-hole convenience: Radial lead package with defined 5 mm lead spacing simplifies prototyping and repairable assemblies.
• RoHS compliance: Meets environmental restrictions for lead-free designs.
