RS81C101MCN1

The RS81C101MCN1 is a radial-lead conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RS8 series designed for compact, high-ripple applications. It delivers 100 µF capacitance at 16 V in a low-profile φ6.3×8 mm can, combining low ESR/ESL characteristics with a small radial package.

Targeted at general-purpose power applications, this part offers measurable advantages for designs that require high-frequency ripple handling, tight board-space constraints, and extended operation up to 105°C.

Key Features

• Conductive polymer aluminum solid electrolyte — Solid electrolyte construction provides stable behavior under ripple and temperature stress as specified for the RS8 series.
• Capacitance and voltage — 100 µF rated capacitance at 16 V for general-purpose decoupling and energy storage needs.
• Low ESR — 14 mΩ ESR measured at 20°C / 100 kHz to support low-loss, high-frequency operation.
• High ripple capability — Rated ripple current of 380 mA at 120 Hz and 3.8 A at 300 kHz, with frequency coefficients provided by the RS8 series for multi-frequency performance.
• Temperature and endurance — Operating range of −55°C to +105°C and endurance rated for 2000 hours at 105°C under rated voltage.
• Low loss tangent and leakage — tan δ ≤ 0.10 (20°C, 120 Hz) and leakage current specified at 500 µA (after 2 minutes at 20°C), enabling predictable loss and charging behavior.
• Compact radial package — φ6.3×8 mm can with 2.5 mm lead spacing (±0.5 mm tolerance) for space-constrained through-hole layouts; available in bulk or bag packing.
• Environmental compliance — RoHS compliant per product data.

Typical Applications

• General-purpose power filtering — Low ESR and specified ripple current make this capacitor suitable for power-supply filtering and decoupling in compact assemblies.
• DC–DC converter output stages — Small radial can with high-frequency ripple capability supports output smoothing in compact converter designs.
• Compact board-level energy storage — 100 µF capacitance in a low-profile package for space-limited PCB layouts requiring bulk capacitance.

Unique Advantages

• Low-loss, high-frequency performance: 14 mΩ ESR at 100 kHz enables efficient handling of high-frequency ripple currents with reduced heating.
• High ripple-current capability: Rated ripple currents of 380 mA (120 Hz) and 3.8 A (300 kHz) provide predictable performance across a wide frequency range.
• Small, low-profile radial package: φ6.3×8 mm can and 2.5 mm lead spacing deliver a compact through-hole solution for tight-layout designs.
• Wide temperature endurance: −55°C to +105°C operating range and 2000-hour endurance at 105°C support sustained operation in elevated-temperature environments.
• Manufacturing-friendly packaging: Available in bulk (no terminal forming) or bag packing to match assembly and inventory workflows.
• Regulatory readiness: RoHS compliance for markets requiring restricted-substance conformity.

Why Choose RS81C101MCN1?
