RKS1D820MCNAJLGS

The RKS1D820MCNAJLGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon’s RKS series. It delivers 82 µF nominal capacitance at a 20 V rating in a compact φ10 × 12.4 mm can-style SMD package, designed for general-purpose power applications.

With a wide operating temperature range of –55°C to 125°C and a rated load life of 3000 hours at 125°C, this capacitor targets designs that require stable capacitance, low ESR, and strong high-frequency ripple handling in compact assemblies.

Key Features

• Conductive polymer aluminum construction — Solid electrolytic chemistry for stable electrical characteristics and long life under heat stress.
• Nominal capacitance and tolerance — 82 µF with ±20% tolerance at 120 Hz, 20°C for predictable bulk storage and decoupling behavior.
• Rated voltage — 20 V DC rating suitable for a variety of low-voltage power rails.
• Low ESR — ESR of 20 mΩ measured at 100 kHz (20°C) to minimize losses and voltage drop under AC ripple.
• High allowable ripple current — 200 mA at 120 Hz (low frequency) and 2 A at 300 kHz (high frequency) to support high-frequency and switching-power environments.
• Wide temperature and long life — Operating range –55°C to 125°C and endurance of 3000 hours at 125°C for reliable performance in elevated-temperature applications.
• Leakage and dissipation — Leakage current specified at 100 µA and tanδ (DF) of 0.12 at 20°C, 120 Hz for controlled loss behavior.
• SMD-compatible packaging — Radial can SMD package supplied in embossed carrier tape with moisture-proof packing; compatible with lead‑free reflow up to 260°C peak per series soldering guidance.

Typical Applications

• Power supply filtering — Bulk and smoothing capacitor for low-voltage power rails where 82 µF and low ESR reduce ripple and improve regulation.
• Switching power converters — Handles high-frequency ripple currents (2 A at 300 kHz) for use on switching node and output stages in compact converters.
• Decoupling in densely packed boards — Compact φ10 × 12.4 mm SMD can provides capacitance and low loss where board real estate is limited.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 200 mA (120 Hz) and 2 A (300 kHz) let designs manage both low- and high-frequency stress without excessive heating.
• Low ESR for efficiency: 20 mΩ ESR at 100 kHz reduces I2R losses and improves transient response in high-frequency applications.
• Thermal robustness: –55°C to 125°C operating range and 3000-hour endurance at 125°C support long-term reliability in elevated-temperature environments.
• Compact SMD form factor: Can-style radial SMD package delivers high capacitance in a small footprint with moisture-proof embossed carrier tape for manufacturing compatibility.
• Controlled leakage and dissipation: 100 µA leakage and tanδ of 0.12 at 20°C, 120 Hz provide predictable loss and leakage behavior for precision power designs.
• RoHS compliance (series level): Series documentation indicates compliance with RoHS directive (2011/65/EU, (EU)2015/863).
