RS81E101MCNASQ

The RS81E101MCNASQ is a conductive polymer aluminum solid electrolytic capacitor in a low-profile radial-can package (φ6.3 × 8 mm). It delivers a compact energy-storage solution with low equivalent series resistance and high ripple-current capability for general-purpose electronic designs.

Designed for robust operation across a wide temperature range (−55°C to 105°C) and specified for 5,000 hours at 105°C, this radial-lead capacitor is intended for applications that require stable capacitance, low loss (tan δ), and reliable ripple handling in a small footprint.

Key Features

• Conductive polymer construction — Solid electrolyte chemistry for improved conductivity and stable electrical performance.
• Capacitance & tolerance — 100 µF with tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Low loss (tan δ) — tanδ = 0.10 measured at 20°C, 120 Hz, supporting stable AC performance.
• Low ESR — ESR approximately 14 mΩ at 20°C/100 kHz, enabling efficient high-frequency operation and reduced dissipation.
• High ripple-current capability — Low-frequency and high-frequency ripple current rated at 3,800 mA, supporting demanding filtering and decoupling tasks.
• Robust leakage and endurance — Leakage current specified at 500 µA (after 2 minutes at 20°C); rated life 5,000 hours at 105°C under endurance test conditions.
• Compact radial package — φ6.3 × 8 mm can with 2.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for easy through-hole assembly.
• Wide operating temperature — Rated for −55°C to +105°C for versatile environmental use.
• RoHS compliant — Meets RoHS directive requirements as stated in product documentation.

Typical Applications

• Power supply decoupling — Low ESR and high ripple-current capability make this capacitor suitable for smoothing and decoupling in compact power rails.
• DC–DC converter output filtering — Small form factor and robust ripple handling support use on converter outputs where space is limited.
• General-purpose electronic circuits — Radial lead format and wide temperature range accommodate a range of through-hole board-level designs requiring reliable capacitance.

Unique Advantages

• High ripple tolerance in a small package — 3.8 A ripple-current rating combined with a φ6.3 × 8 mm can allows designers to meet filtering requirements without increasing board area.
• Low dissipation at high frequency — Low ESR (~14 mΩ at 100 kHz) reduces power loss and thermal stress in high-frequency applications.
• Long endurance at elevated temperature — 5,000-hour life rating at 105°C supports designs requiring extended reliability under heat stress.
• Through-hole compatibility — Radial lead and standard 2.5 mm lead spacing simplify prototyping and replacement in legacy or mixed-technology assemblies.
• Predictable AC performance — Specified tanδ and leakage current provide clear electrical behavior for AC and DC design margins.
