RHA1C271MCNBSQGS

The RHA1C271MCNBSQGS is a conductive polymer aluminum solid electrolytic capacitor in an SMD radial can package, offering 270 µF capacitance at a 16 V rating. It is designed for general-purpose electronic designs that require compact, high-capacitance SMD components.

This part combines low ESR (16 mΩ at 100 kHz) with high ripple-current capability (407 mA at 120 Hz and 4.07 A at 300 kHz) and extended endurance (5,000 hours at 105 °C), delivering reliable smoothing and bulk energy storage in compact surface-mount layouts.

Key Features

• Capacitance and Voltage — 270 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance, providing stable bulk capacitance for general-purpose power circuitry.
• Low ESR and High-Frequency Performance — ESR of 16 mΩ at 20 °C/100 kHz, supporting effective high-frequency ripple handling; frequency coefficients provided (e.g., 0.10 at 120 Hz, 1.00 at 100–300 kHz) to size ripple performance accurately.
• High Ripple Current Capability — Rated ripple currents of 407 mA at 120 Hz and 4.07 A at 300 kHz, enabling robust operation under AC ripple stress and high-frequency switching environments.
• Long Endurance — Load life specified at 5,000 hours at 105 °C, with defined limits for capacitance change, tan δ, ESR, and leakage after endurance testing.
• Wide Operating Temperature Range — Specified for −55 °C to +105 °C to cover a broad set of environmental and thermal conditions.
• Compact Surface-Mount Package — φ8 × 8.7 mm package (surface-mount radial can) with recommended land size 8.3 × 8.3 mm, offered in embossed carrier taping with moisture-proof packing for automated assembly.
• Low Loss — tan δ of 0.12 (120 Hz, 20 °C) to help maintain efficiency in AC and switching circuits.
• RoHS Compliant and Production Ready — RoHS-compliant construction and listed as mass production status.

Typical Applications

• Power Supply Filtering — Provides bulk smoothing and output filtering for DC–DC converters and linear regulators, leveraging low ESR and high ripple-current ratings.
• Switch-Mode Power Supplies — Suited to high-frequency switching environments where the 4.07 A ripple capability at 300 kHz and the frequency coefficient data support accurate ripple-current design.
• General Purpose Electronic Designs — Compact SMD form factor and broad temperature range make it suitable for a wide range of general-purpose board-level power applications.

Unique Advantages

• Low ESR for Improved Efficiency: 16 mΩ ESR at 100 kHz reduces power loss and heat generation in high-frequency circuits.
• High Ripple-Current Handling: Rated ripple currents up to 4.07 A (300 kHz) enable reliable performance under heavy AC stress from switching supplies.
• Extended High-Temperature Life: 5,000-hour endurance at 105 °C supports long-term reliability in thermally demanding designs.
• Compact SMD Radial Can: φ8 × 8.7 mm packaging delivers high capacitance in a small footprint for space-constrained PCBs.
• Design Predictability: Specified tan δ, leakage current, and frequency coefficients help engineers size and validate performance under real operating conditions.
• Manufacturing Ready: Embossed carrier taping and moisture-proof packing simplify automated placement and handling for volume assembly.
