RNL1C182MDS4

The RNL1C182MDS4 is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, offering 1.8 mF capacitance at a 16 V rating. It combines high capacitance, low ESR and elevated ripple-current capability in a compact φ10×16 mm package for general-purpose electronic designs.

Engineered for demanding thermal environments, the part is specified for operation from −55°C to 105°C and a rated load life of 2000 hours at 105°C, providing predictable electrical performance over extended use.

Key Features

• Core electrical — 1.8 mF (1800 µF) capacitance at 16 V with ±20% tolerance, suitable where substantial bulk capacitance is required.
• Low loss / frequency behavior — tanδ of 0.12 measured at 20°C, 120 Hz, supporting stable AC performance in filtering applications.
• Very low ESR — 8 mΩ measured at 20°C/100 kHz, enabling efficient high-frequency current delivery and reduced power dissipation.
• High ripple-current capability — rated ripple currents of 770 mA at 120 Hz (low frequency) and 7.7 A at 300 kHz (high frequency), allowing effective smoothing under AC and switching conditions.
• Reliability and endurance — load life specified as 2000 hours at 105°C; leakage current specified at 2880 µA (after 2 minutes at 20°C), with defined end-of-life limits for capacitance, tanδ and ESR in the datasheet.
• Package and mounting — radial lead, φ10×16 mm can with 5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through-hole assembly.
• Operating temperature — rated for −55°C to 105°C to support a wide range of ambient conditions.
• RoHS compliant — constructed in accordance with RoHS requirements listed in the product data.

Typical Applications

• General-purpose electronic designs — suitable for applications requiring high bulk capacitance and low ESR in a radial-lead package.
• Power supply filtering — designed to handle high ripple currents and provide stable decoupling at frequencies up to 300 kHz.
• Industrial and commercial equipment — rated for −55°C to 105°C and a 2000-hour life at 105°C for reliable operation in elevated-temperature environments.

Unique Advantages

• High capacitance in a compact can — 1800 µF in a φ10×16 mm package reduces board area compared with larger through-hole alternatives.
• Low ESR for improved power efficiency — 8 mΩ at 100 kHz limits voltage drop and heat generation under high-frequency ripple.
• Broad ripple-current capability — specified ripple ratings at both low and high frequencies (770 mA @120 Hz, 7.7 A @300 kHz) accommodate switching and linear supply roles.
• Designed for elevated temperatures — endurance rating of 2000 hours at 105°C supports applications with sustained thermal stress.
• Through-hole convenience — radial leads with 5 mm spacing simplify prototyping and replacement in production assemblies.
• Regulatory alignment — RoHS compliance supports use in assemblies targeting restricted-substance requirements.
