RL81C471MCNASQ

The RL81C471MCNASQ is a Nichicon RL8 series conductive polymer aluminum solid electrolytic capacitor in a low-profile radial lead can (φ8×8 mm). It delivers 470 µF capacitance at a 16 V rating with a wide operating temperature range of −55°C to +105°C and is available in mass production with bulk or bag packing.

Designed for general-purpose smoothing and decoupling where low ESR and high ripple capability matter, this radial-lead part combines compact size, 5000-hour endurance at 105°C, and electrolytic performance tailored for power filtering in compact systems.

Key Features

• Conductive polymer architecture Solid electrolytic construction using conductive polymer for stable capacitance and lower ESR compared to conventional wet electrolytics.
• Low ESR ESR specified at 16 mΩ measured at 20°C / 100 kHz, supporting high-frequency decoupling and efficient power delivery.
• High ripple current capability Rated ripple current of 400 mA at 120 Hz and 4.0 A at 300 kHz to support both low- and high-frequency ripple suppression.
• Compact, low-profile radial package Case size φ8 × 8 mm with radial leads and 3.5 mm lead spacing (±0.5 mm), enabling space-efficient PCB layouts and through-hole mounting.
• Temperature and endurance Rated for −55°C to +105°C with a load life of 5000 hours at 105°C, providing durability in elevated-temperature environments.
• Electrical characteristics Capacitance 470 µF with tolerance −20% to +20%, tangent of loss angle (tan δ) 0.12 at 20°C / 120 Hz, and leakage current listed at 1504 µA.
• Compliance and availability RoHS-compliant and listed as mass production; available in Bulk (no terminal forming) or Bag packing options.

Typical Applications

• Power supply smoothing Bulk and high-frequency ripple suppression on DC power rails where compact, low-ESR capacitors are required.
• Point-of-load decoupling Local decoupling for regulators and power converters that benefit from low ESR at high frequency.
• Embedded and industrial electronics General-purpose energy storage and filtering in compact, elevated-temperature designs.

Unique Advantages

• Low ESR for improved transient response: 16 mΩ (20°C / 100 kHz) ESR helps reduce voltage sag during load transients and improves regulator stability.
• High-frequency ripple handling: 4.0 A ripple current capability at 300 kHz supports modern switching converters and high-speed power circuits.
• Compact, low-profile form factor: φ8×8 mm case delivers substantial capacitance in a small footprint for space-constrained PCBs.
• Extended high-temperature life: 5000 hours at 105°C provides predictable endurance for designs exposed to sustained elevated temperatures.
• Radial lead mounting: Through-hole radial leads and defined lead spacing simplify assembly for boards that require robust mechanical mounting.
• RoHS-compliant production: Environmentally compliant manufacturing as indicated in the product data.

Why Choose RL81C471MCNASQ?

The RL81C471MCNASQ positions itself as a compact, low-ESR conductive polymer solution for designers needing 470 µF at 16 V with strong high-frequency ripple performance and extended endurance at elevated temperatures. Its φ8×8 mm low-profile can and radial-lead format make it well suited to through-hole assemblies where board space is limited but reliable power filtering is required.

This part is appropriate for engineers specifying robust decoupling or smoothing capacitors in embedded, industrial, and power supply applications that demand predictable ESR, measurable ripple current performance, and long life at 105°C.
