RHA1C471MCN1GS

The RHA1C471MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount can package (series: RHA). With 470 µF nominal capacitance at 16 V and a wide operating temperature range of −55 °C to 105 °C, it is designed for general-purpose power applications that require high capacitance, low loss and robust ripple performance. Its combination of low ESR and high ripple current capability supports power rail smoothing, decoupling and bulk energy storage in compact SMD assemblies.

Key Features

• Capacitance & Tolerance — 470 µF nominal with ±20% tolerance at 120 Hz, 20 °C for predictable bulk storage.
• Voltage Rating — Rated for 16 V operation for common low-voltage power rails.
• Low Loss & Stability — Tangent of loss angle (tanδ) of 0.12 and ESR of 16 mΩ measured at 20 °C/100 kHz, enabling efficient high-frequency performance.
• High Ripple Current Handling — Rated ripple current 400 mA at 120 Hz and 4 A at 300 kHz (frequency coefficient supported), suitable for both low- and high-frequency filtering.
• Reliability & Life — Endurance rated for 2000 hours at 105 °C under rated voltage conditions, with leakage current specified at 1504 µA after standard conditioning.
• Package & Mounting — Surface-mount radial can (φ8 × 8.7 mm), surface mount land size L: 8.3 × W: 8.3 mm, supplied in embossed carrier taping with moisture-proof packing.
• RoHS Compliant — Meets RoHS requirements for restricted substances.
• Assembly Compatibility — SMD type supports lead-free reflow soldering process with a 260 °C peak reflow condition (series specification).

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple reduction on low-voltage DC power rails, leveraging 470 µF capacitance and 4 A ripple capability at high frequency.
• DC‑DC Converter Output — Output decoupling and energy storage for switching converters where low ESR (16 mΩ @100 kHz) reduces voltage ripple and loss.
• High‑Frequency Decoupling — Local decoupling for high-frequency circuits using the capacitor’s low tanδ (0.12) and high ripple current at 300 kHz.
• General Purpose Electronic Modules — Compact SMD bulk capacitance for embedded and board-level power conditioning in consumer and industrial modules.

Unique Advantages

• High Capacitance in a Compact SMD Can — 470 µF in a φ8 × 8.7 mm package provides substantial bulk energy storage while keeping board area small.
• Low ESR at High Frequency — 16 mΩ at 20 °C/100 kHz minimizes loss and heat generation during high-frequency operation.
• Strong Ripple Performance — Dual ripple specs (400 mA at 120 Hz and 4 A at 300 kHz) support both mains-frequency smoothing and fast switching applications.
• Wide Temperature Range — Rated −55 °C to 105 °C to tolerate a broad set of operating environments.
• Production‑Ready Packaging — Embossed carrier taping with moisture-proof packing simplifies automated assembly and inventory handling.
• Designed for Reflow Assembly — Compatible with lead-free reflow processes (260 °C peak specification) for modern surface-mount manufacturing.
