RS81C271MDN1

The RS81C271MDN1 is a Nichicon RS8 series conductive polymer aluminum solid electrolytic capacitor in a radial-lead can. It provides 270 µF capacitance at a 16 V rating with a low-profile φ6.3 × 8 mm package and 2.5 mm lead spacing for compact through‑hole designs.

Designed for general-purpose applications that require low equivalent series resistance and high ripple handling, this part delivers measurable benefits in power filtering, decoupling and output smoothing across a wide operating temperature range.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance at a 16 V rated voltage with tolerance ±20% (–20% to +20%) measured at 120 Hz, 20°C.
• Low ESR — ESR of 15 mΩ measured at 20°C / 100 kHz, supporting reduced voltage ripple and lower power dissipation in high-frequency circuits.
• High Ripple Current Capability — Rated ripple current of 380 mA at 120 Hz (low frequency) and 3.8 A at 300 kHz (high frequency) for demanding AC/ switching environments.
• Thermal & Endurance Specs — Operating temperature range from –55°C to +105°C with a rated life of 2000 hours at 105°C.
• Loss Tangent — tan δ = 0.10 (measured at 20°C, 120 Hz) for predictable dielectric loss performance.
• Leakage Current — Specified leakage current of 1296 µA (after 2 minutes at rated voltage, 20°C).
• Form Factor & Mounting — Radial lead can (φ6.3 × 8 mm) with 2.5 mm lead spacing (tolerance ±0.5 mm) for through‑hole assembly.
• Packaging & Compliance — Available in bulk (no terminal forming) and bag packing; RoHS compliant and in mass production.

Typical Applications

• Power supply decoupling — Low ESR and high ripple current capability help reduce output voltage ripple in switching and linear supplies.
• Point‑of‑load filtering — Compact, low‑profile radial package supports tight board layouts for local filtering at regulator outputs.
• General-purpose electronics — Suitable for a wide range of general-purpose circuits that require reliable capacitance and thermal endurance.

Unique Advantages

• Measurable low-loss performance — 15 mΩ ESR at 100 kHz and tan δ = 0.10 enable lower dissipation and predictable AC behavior in high-frequency circuits.
• High ripple tolerance — Rated ripple currents up to 3.8 A at high frequency reduce self-heating and extend operational stability in switching environments.
• Compact low-profile package — φ6.3 × 8 mm can with 2.5 mm lead spacing minimizes board area while supporting through‑hole mounting and robust mechanical retention.
• Wide temperature range and proven life — –55°C to +105°C operating range and 2000 h endurance at 105°C provide reliability in thermally demanding applications.
• Pick-and-place friendly packaging options — Bulk and bag packing choices accommodate different assembly workflows.
• RoHS compliant and production-ready — Mass production status and RoHS compliance support procurement and regulatory requirements.
