RNU1C271MCNASQ

The RNU1C271MCNASQ is a Nichicon RNU series conductive polymer aluminum solid electrolytic capacitor in a radial lead can. It provides 270 µF capacitance at a 16 V rating with low ESR and high ripple current capability for general-purpose electronic designs.

Designed for applications requiring compact, high-capacitance decoupling and smoothing within a wide temperature range, the part combines a small φ8×11.5 mm package and radial lead mounting with a rated operating range of −55°C to 105°C and a 5,000 hour endurance at 105°C.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a rated voltage of 16 V and tolerance of −20% to +20%.
• Conductive Polymer Electrolyte — Solid conductive polymer construction for stable performance and reduced equivalent series resistance compared with conventional electrolytes.
• Low ESR — ESR of 8 mΩ measured at 20°C/100 kHz, supporting efficient high-frequency operation.
• High Ripple Current — Rated ripple current of 500 mA at 120 Hz (low frequency) and 5 A at 300 kHz (high frequency) to handle demanding ripple conditions.
• Loss Angle — tanδ of 0.08 measured at 20°C/120 Hz for predictable dissipation characteristics.
• Electrical Leakage — Leakage current specified at 864 µA (measured after 2 minutes at 20°C), enabling predictable standby and bias behavior.
• Reliability & Lifetime — Endurance specified to 5,000 hours at 105°C under rated voltage conditions.
• Package & Mounting — Radial lead can, case size φ8×11.5 mm, lead spacing 3.5 mm (±0.5 mm), available in bulk (no terminal forming) or bag packing.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose electronics — For circuits requiring 270 µF at 16 V with low ESR and defined high-frequency ripple capability.
• Power supply decoupling — Used where compact, high-capacitance radial lead components are needed within −55°C to 105°C operating range.
• High-frequency ripple handling — Suited to designs that require rated ripple currents up to 5 A at 300 kHz and low ESR at 100 kHz.

Unique Advantages

• Low ESR for efficient HF performance: 8 mΩ ESR at 20°C/100 kHz reduces voltage drop and heat generation under high-frequency ripple.
• High ripple capability: 5 A rated ripple at 300 kHz and 500 mA at 120 Hz lets designers handle both low- and high-frequency ripple requirements.
• Compact radial package: φ8×11.5 mm can with 3.5 mm lead spacing provides a space-efficient through-hole solution for board-level integration.
• Long endurance at elevated temperature: 5,000 hours at 105°C supports long-term reliability in thermally demanding environments.
• Predictable electrical characteristics: Specified tanδ (0.08) and leakage current (864 µA) enable reliable power-budgeting and thermal design.
• Production-ready availability: Mass production status and standard bulk/bag packing options simplify procurement and assembly planning.
