RHA1C271MCN1GS

The RHA1C271MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial-can (φ8) package delivering 270 µF at 16 V. It provides low ESR and high ripple current performance in a compact SMD form factor, targeted for general-purpose surface-mount applications that require reliable bulk capacitance and power filtering.

This part is designed for elevated-temperature operation with a rated temperature range of −55 °C to 105 °C and a specified load life of 2000 hours at 105 °C. It is compatible with lead-free reflow soldering (260 °C peak) and is RoHS compliant.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance at 16 V provides substantial bulk energy storage for power rail stabilization and transient suppression.
• Low ESR — 22 mΩ ESR measured at 100 kHz (20 °C) reduces internal losses and improves high-frequency performance.
• High Ripple Current — Rated ripple current of 330 mA at 120 Hz and 3.3 A at 300 kHz supports demanding AC and switching environments.
• Temperature & Lifetime — Operating range −55 °C to 105 °C with a load life rating of 2000 hours at 105 °C for sustained high-temperature use.
• SMD Package & Land Pattern — Compact dimensions L: 6.7 × D: 8 mm with recommended land size 8.3 × 8.3 mm for space-constrained surface-mount assemblies.
• Assembly Compatibility — Suitable for lead-free reflow soldering with peak temperature up to 260 °C.
• Regulatory — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized — Polar capacitor for correct-oriented SMD power designs; capacitance tolerance −20% to 20%.

Typical Applications

• General-purpose surface-mount power filtering — Bulk capacitance and low ESR make the part suited to smoothing and stabilizing power rails in compact assemblies.
• High-frequency ripple suppression — High ripple current rating at 300 kHz supports switching regulator output filtering and decoupling near power stages.
• Elevated-temperature electronics — Rated for −55 °C to 105 °C with a 2000-hour life at 105 °C for sustained operation in thermally demanding environments.

Unique Advantages

• High ripple current capability: 3.3 A at 300 kHz lets designers handle significant AC stress without oversizing the capacitor bank.
• Low ESR reduces losses: 22 mΩ at 100 kHz lowers conduction losses and improves voltage stability under load.
• Compact SMD radial-can footprint: 6.7 × 8 mm case and 8.3 × 8.3 mm recommended land save board area while providing high capacitance.
• Lead-free reflow compatible: Peak reflow temperature rating of 260 °C supports modern lead-free assembly processes.
• Durable at temperature: 2000-hour load life at 105 °C offers predictable performance for designs that operate at elevated temperatures.
• RoHS compliance: Meets RoHS requirements (2011/65/EU, (EU)2015/863) for regulatory conformity.
