The RKS1D820MCNAHHGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 82 µF at a 20 V rating. It combines low ESR and high allowable ripple current with a long endurance rating to support demanding board-level power applications.

Engineered for high-temperature operation and SMD assembly, this part delivers a specified operating range of -55°C to 125°C and a rated load life of 3000 hours at 125°C, making it suitable where stable capacitance, low loss, and thermal robustness are required.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance at a rated voltage of 20 V with capacitance tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Low Loss / Low ESR — Tangent of loss angle (tan δ) specified at 0.12 (20°C, 120 Hz) and ESR 30 mΩ at 20°C / 100 kHz, supporting efficient high-frequency performance.
• High Ripple Current Capability — Low-frequency ripple current of 160 mA (120 Hz) and high-frequency ripple current of 1.6 A (300 kHz) for handling switching and transient currents.
• Long High-Temperature Life — Rated endurance of 3000 hours at 125°C under rated voltage, with defined limits for capacitance change, tan δ and ESR after life test.
• Wide Operating Temperature — Specified for use from -55°C to 125°C to maintain performance across harsh thermal environments.
• SMD Radial Can Package — Compact φ8 × 8.7 mm can-style SMD package with surface-mount land recommendations (8.3 × 8.3 mm); supplied in embossed carrier tape with moisture-proof packing for automated placement.
• Reflow Compatible — Designed for lead-free reflow soldering up to a 260°C peak with recommended pre-heat profiles and up to two reflow cycles at ≤260°C, per the product series soldering heat specifications.
• Leakage Current — Specified leakage current up to 100 µA (after standard conditioning), suitable for power applications where controlled leakage is required.
• RoHS Compliance — The product series is stated as compliant with the RoHS directive (2011/65/EU, (EU)2015/863) in product documentation.

Typical Applications

• High-temperature power stages — Provides stable capacitance and low ESR in power electronics operating at elevated temperatures.
• Switching power supplies and converters — Handles both low- and high-frequency ripple currents for smoothing and decoupling in switching environments.
• SMD power modules — Compact radial-can SMD package and embossed carrier taping support automated placement in power-density designs.
• Board-level bulk and decoupling — Useful where long high-temperature life and controlled leakage are needed for reliable bulk energy storage and decoupling.

Unique Advantages

• Performance at elevated temperature: Rated 3000 hours at 125°C, delivering predictable end-of-life characteristics for thermal-stressed applications.
• High ripple tolerance with low ESR: 1.6 A at 300 kHz combined with 30 mΩ ESR (100 kHz) reduces power losses and temperature rise under AC stress.
• SMD-ready packaging: Embossed carrier taping and moisture-proof packing simplify integration into automated assembly lines.
• Lead‑free reflow compatibility: Specified peak reflow temperature up to 260°C (with recommended pre-heat and reflow limits) for modern Pb‑free assembly processes.
• Compact form factor: φ8 × 8.7 mm can-style SMD provides high capacitance in a small board footprint for space-constrained designs.
