RNL1C182MDS1

The RNL1C182MDS1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, designed for general-purpose electronic applications that require high capacitance and low equivalent series resistance. Its 16 V rated voltage and 1.8 mF capacitance combine with engineered low ESR and high ripple current capability to support demanding power-conditioning roles in compact assemblies.

Built for durability, the part is specified for operation from −55°C to 105°C with a rated load life of 2000 hours at 105°C, and is available in bulk or bag packing for production deployment.

Key Features

• Conductive polymer architecture — Solid electrolyte construction provides low ESR and stable performance across frequency.
• High capacitance — 1.8 mF (1800 µF) nominal capacitance for bulk energy storage in a φ10×20 mm radial can.
• Rated voltage — 16 V nominal rating suitable for many general-purpose power rails.
• Low ESR — 8 mΩ measured at 20°C / 100 kHz, supporting reduced loss and improved high-frequency response.
• Strong ripple capability — 810 mA at 120 Hz (low frequency) and 8.1 A at 300 kHz (high frequency) for handling varying ripple conditions.
• Thermal and life rating — Operating range −55°C to 105°C with a load life (endurance) of 2000 hours at 105°C.
• Electrical characteristics — tan δ = 0.12 (20°C, 120 Hz) and leakage current specified at 2880 µA.
• Radial lead package — φ10×20 mm can with 5 mm lead spacing (±0.5 mm) for through-hole mounting and easy handling; available in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk capacitance for smoothing and energy storage on DC rails in a wide range of electronic equipment.
• High-frequency power circuits — Low ESR and high ripple current capability make it suitable where AC components at higher frequencies must be managed.
• Industrial and consumer electronics — Designed for general-purpose use across product types that require robust temperature range and long operating life.

Unique Advantages

• High capacitance in a compact radial can: 1.8 mF in a φ10×20 mm package provides substantial bulk storage without requiring larger footprints.
• Low ESR at high frequency: 8 mΩ (20°C/100 kHz) supports lower losses and better high-frequency performance compared with higher-ESR alternatives.
• Wide operating temperature: Rated from −55°C to 105°C, enabling use across diverse thermal environments.
• High ripple current capability: 810 mA at 120 Hz and 8.1 A at 300 kHz allow reliable operation under both low- and high-frequency ripple conditions.
• Designed for production: Available in bulk or bag packing and listed as mass production status for supply chain readiness.
• RoHS compliant: Meets environmental regulations for lead-free manufacturing requirements.
