RNU1C271MDNASQ

The RNU1C271MDNASQ from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can, rated 270 µF at 16 V. It delivers low ESR and high ripple current in a compact φ8×11.5 mm package for general-purpose electronic designs.

Designed for demanding power-decoupling and smoothing roles, this capacitor combines a wide operating temperature range (−55°C to +105°C) and a 5000-hour endurance at 105°C for reliable performance in continuous-duty applications.

Key Features

• Capacitance & Voltage: 270 µF nominal capacitance with a rated voltage of 16 V and tolerance of −20% to +20% for predictable charge storage.
• Low ESR & High-Frequency Performance: ESR of 8 mΩ measured at 20°C and 100 kHz, with a tanδ of 0.08 at 20°C and 120 Hz for efficient high-frequency filtering.
• High Ripple Current Capability: Low-frequency ripple current 500 mA (120 Hz) and high-frequency ripple current 5 A (300 kHz) to support dynamic power delivery requirements.
• Thermal and Lifetime Ratings: Rated for operation from −55°C to +105°C with an endurance (load life) of 5000 hours at 105°C under rated voltage conditions.
• Form Factor & Mounting: Radial lead package, case φ8×11.5 mm (L), lead spacing 3.5 mm ±0.5 mm, supplied in bulk/bag packing with no terminal forming required.
• Leakage Current: Specified leakage current of 864 µA (measured after 2 minutes at 20°C under rated voltage) for predictable standby behavior.
• RoHS Compliance: Compliant with RoHS directive as noted in product data.

Typical Applications

• Power supply filtering and decoupling: Low ESR (8 mΩ) and high ripple current capability (up to 5 A at 300 kHz) support smoothing and transient handling in power rails.
• DC–DC converter output caps: Compact φ8×11.5 mm size and high-frequency performance make it suitable for output-stage energy storage in converter modules.
• General-purpose electronics: Broad temperature range (−55°C to +105°C) and 5000-hour endurance at 105°C fit continuous-duty applications across consumer and industrial designs.

Unique Advantages

• Compact high-capacitance package: 270 µF in a φ8×11.5 mm radial can provides significant capacitance density for space-constrained boards.
• Improved efficiency at high frequency: 8 mΩ ESR at 100 kHz and tanδ 0.08 (120 Hz) reduce power loss and heating in high-frequency circuits.
• Robust ripple handling: Rated ripple currents of 500 mA (120 Hz) and 5 A (300 kHz) help maintain voltage stability under dynamic loads.
• Long-term thermal endurance: 5000 hours at 105°C under rated voltage supports designs subjected to sustained elevated temperatures.
• Design-ready radial format: Standard 3.5 mm lead spacing (±0.5 mm) and bulk/bag packing simplify through-hole assembly and inventory handling.
• Regulatory compliance: RoHS status included for straightforward inclusion in compliant product lines.
