RHA1C271MCN9GS

The RHA1C271MCN9GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package. It delivers 270 µF at 16 V with low ESR and high ripple-current capability for compact power and decoupling applications.

Designed for general-purpose electronic systems, this SMD capacitor supports wide operating temperatures (−55 °C to 105 °C) and a rated life of 2000 hours at 105 °C, making it suitable for space‑constrained power modules and high-frequency filtering tasks.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with ±20% tolerance, rated for 16 V operation.
• Low Loss / Stable AC Performance — tan δ = 0.12 (measured at 20 °C, 120 Hz), helping minimize dissipation in AC and ripple conditions.
• Very Low ESR — 16 mΩ measured at 20 °C / 100 kHz, enabling efficient high-frequency energy transfer and reduced heat generation.
• High Ripple Current Capability — 400 mA at 120 Hz (low frequency) and up to 4 A at higher frequencies (300 kHz coefficient = 1.00), suitable for DC‑DC converter outputs and switching power supplies.
• Leakage Current — 864 µA (measured after 2 minutes at 20 °C), providing predictable standby characteristics.
• Reliability / Endurance — Rated load life of 2000 hours at 105 °C under rated voltage conditions.
• Package & Mounting — Surface-mount radial can, size φ8 × 8.7 mm (L), with recommended land size L: 8.3 × W: 8.3 mm; supplied in embossed carrier taping with moisture‑proof packing.
• Reflow Compatibility — SMD type suitable for lead‑free reflow soldering with peak correspondence at 260 °C.
• Environmental — RoHS compliant.

Typical Applications

• DC‑DC converter output filtering — Low ESR and high ripple current capacity reduce output voltage ripple and thermal stress in compact converter designs.
• Power-supply decoupling — High capacitance in a small φ8 package supports local decoupling for point‑of‑load regulation and power integrity.
• Switching power stages — Stable high-frequency performance (ESR at 100 kHz) and tan δ characteristics help manage losses in switching environments.
• Compact power modules — Small SMD radial can footprint and embossed-tape packaging simplify automated assembly in space‑constrained boards.

Unique Advantages

• High capacitance in a compact SMD can — 270 µF in a φ8×8.7 mm package reduces board area while delivering bulk energy storage.
• Predictable high‑frequency behavior — ESR specified at 100 kHz (16 mΩ) and frequency coefficients support designers targeting high-frequency ripple handling.
• Robust thermal endurance — 2000 hours at 105 °C rating gives designers a clear reliability baseline for elevated-temperature operation.
• Manufacturing-ready packaging — Embossed carrier taping with moisture-proof packing and lead-free reflow compatibility streamline assembly and handling.
• Measured leakage specification — Specified leakage current (864 µA) measured under standard conditions provides clear leakage budgeting for power designs.
• Regulatory compliance — RoHS compliance supports use in regions and supply chains requiring lead‑free components.
