RL81C181MDNASQ

The RL81C181MDNASQ from Nichicon’s RL8 series is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial-lead can (φ8×8 mm). It provides 180 µF nominal capacitance at a 16 V rating with low equivalent series resistance and engineered ripple-current capability for general-purpose electronic designs.

Designed for compact assemblies, the part combines low ESR, defined ripple-current ratings at both low and high frequencies, and a 5000-hour life at 105°C to support reliable decoupling and energy-storage duties in a wide range of applications.

Key Features

• Capacitance & Voltage — 180 µF nominal with capacitance tolerance of −20% to +20% at 20°C/120 Hz; rated voltage 16 V.
• Low ESR — ESR of 12 mΩ measured at 20°C/100 kHz, enabling efficient high-frequency performance and reduced loss in switching environments.
• Ripple Current Performance — Low-frequency ripple current 500 mA at 120 Hz and high-frequency ripple current 5 A at 300 kHz, with frequency coefficients provided across 120 Hz–300 kHz.
• Low Loss (tan δ) — tanδ = 0.12 measured at 20°C/120 Hz, suitable for stable filtering behavior.
• Temperature & Endurance — Operating range −55°C to 105°C with a rated load life of 5000 hours at 105°C under rated voltage.
• Package & Mounting — Radial lead mounting in a φ8×8 mm can, lead spacing 3.5 mm (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Leakage Current — Specified leakage current 576 µA (measured after application of rated voltage at 20°C per datasheet conditions).
• RoHS Compliance — Manufactured to meet RoHS requirements.

Typical Applications

• General-purpose power decoupling — Bulk and output filtering where low ESR and defined ripple handling improve regulator stability.
• High-frequency switching supplies — Suitable for smoothing and energy storage at switching frequencies up to the high-kHz range thanks to a 5 A rating at 300 kHz and low ESR.
• Compact consumer and industrial electronics — Low-profile φ8×8 mm can and radial-lead format for space-constrained through-hole designs.

Unique Advantages

• Low ESR for efficient performance: 12 mΩ at 20°C/100 kHz reduces conduction loss and improves high-frequency decoupling effectiveness.
• High ripple capability across frequencies: 500 mA at 120 Hz and 5 A at 300 kHz, plus documented frequency coefficients, let designers size capacitors for both low- and high-frequency ripple scenarios.
• Compact, low-profile package: φ8×8 mm can with 3.5 mm lead spacing supports compact board layouts and through-hole assembly workflows.
• Robust thermal endurance: Rated for −55°C to 105°C with a 5000-hour life at 105°C, enabling sustained operation in elevated-temperature environments.
• Predictable loss characteristics: tanδ = 0.12 at 20°C/120 Hz provides a clear metric for design validation and stability analysis.
• Regulatory alignment: RoHS-compliant construction supports environmental and regulatory requirements.
