RKS1E820MCNAJJGS

The RKS1E820MCNAJJGS is a surface-mount conductive-polymer aluminum solid electrolytic capacitor with a rated capacitance of 82 µF and a rated voltage of 25 V. It is presented in a compact φ10 × 10 mm can-style SMD package and is supplied in embossed carrier tape with moisture-proof packing for production assembly.

Engineered for general-purpose power applications, the device combines low equivalent series resistance (20 mΩ at 100 kHz) with high allowable ripple current (2.0 A at 300 kHz) and a wide operating temperature range of −55 °C to +125 °C. The part is specified for 3,000 hours of life at 125 °C.

Key Features

• Capacitance & Voltage: 82 µF capacitance at a 25 V rated voltage suitable for a broad range of power supply decoupling and bulk storage needs.
• Low ESR: 20 mΩ ESR measured at 20 °C / 100 kHz for reduced voltage drop and heat generation under high-frequency switching conditions.
• High Ripple Handling: High-frequency ripple current rating of 2.0 A (300 kHz) and low-frequency ripple current of 200 mA (120 Hz) to support switching regulators and noisy power rails.
• Loss Tangent (tan δ): tan δ = 0.12 measured at 20 °C, 120 Hz, providing predictable AC loss characteristics for filtering and decoupling.
• Leakage Current: Specified leakage current of 102 µA after rated voltage application, supporting stable long-term bias behavior.
• High Temperature Endurance: Rated endurance of 3,000 hours at 125 °C, enabling sustained operation in elevated-temperature environments.
• Wide Temperature Range: Operates from −55 °C to +125 °C to accommodate a variety of embedded and industrial thermal profiles.
• Packaging & Assembly: φ10 × 10 mm SMD can package in embossed carrier taping with moisture-proof packing for automated placement and storage.
• Regulatory: Series documentation indicates compliance with RoHS directive requirements.

Typical Applications

• Power-supply filtering: Use on DC-DC converter outputs and regulator outputs where 82 µF and low ESR reduce output ripple and improve transient response.
• Switching regulator decoupling: Supports high-frequency ripple currents up to 2.0 A, making it suitable for decoupling around switching power stages.
• Bulk energy storage on PCBs: Compact SMD can-package provides bulk capacitance in space-constrained embedded and industrial designs.

Unique Advantages

• Low-power loss in high-frequency environments: 20 mΩ ESR at 100 kHz and a tan δ of 0.12 minimize dissipation in switching applications.
• High ripple tolerance: 2.0 A high-frequency ripple current rating allows the capacitor to handle aggressive switching currents without excessive heating.
• Extended high-temperature life: 3,000-hour rated life at 125 °C provides predictable longevity in thermally demanding systems.
• Compact SMD form factor: φ10 × 10 mm can package and taped packaging reduce board footprint while remaining assembly-friendly.
• Stable leakage behavior: Specified leakage current of 102 µA helps maintain predictable bias conditions in power rails and hold-up circuits.
• RoHS-aligned series documentation: Series-level compliance information supports environmental requirements for modern electronics production.
