RKS1H820MCNAJJGS

The RKS1H820MCNAJJGS is a surface‑mount conductive polymer aluminum electrolytic capacitor in Nichicon’s RKS series, rated at 82 µF and 50 V. It combines low ESR and high allowable ripple current with a compact φ10×10L SMD can suitable for automated assembly.

Designed for general‑purpose power and decoupling use, this part targets applications requiring high frequency ripple handling, long-term reliability at elevated temperatures, and compact SMD packaging for production environments.

Key Features

• Capacitance & tolerance — 82 µF nominal with ±20% tolerance at 20°C, 120 Hz for predictable bulk and decoupling performance.
• Voltage rating — 50 V rated voltage suitable for mid‑voltage power rails.
• Low ESR — 25 mΩ equivalent series resistance measured at 100 kHz, minimizing loss and voltage drop at high frequencies.
• High allowable ripple current — 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) to support switching regulators and high‑frequency decoupling.
• Loss tangent (tan δ) — 0.12 measured at 20°C, 120 Hz, for controlled dielectric losses.
• Leakage current — 205 µA specified steady‑state leakage for predictable standby and power‑down behavior.
• Extended high‑temperature endurance — 3000 hours life rating at 125°C for robust operation in thermally demanding environments.
• Wide operating range — −55°C to +125°C, supporting broad environmental conditions.
• SMD can package & tape‑and‑reel — φ10×10L radial can in an SMD form factor with embossed carrier taping and moisture proof packing for automated PCB assembly.
• RoHS compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863) as stated in the product series datasheet.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple reduction on mid‑voltage rails where 50 V rating and 82 µF capacitance are required.
• Switching regulator decoupling — Low ESR and high high‑frequency ripple current capability support DC‑DC converter output filtering and transient suppression.
• General‑purpose industrial electronics — Robust temperature endurance and long life make it suitable for control boards and instrumentation operating across a wide thermal range.

Unique Advantages

• Low loss at high frequency: 25 mΩ ESR at 100 kHz and 1.6 A high‑frequency ripple capability reduce heating and improve regulator stability.
• Long life at elevated temperature: 3000 hours at 125°C supports reliability in thermally challenging designs.
• Compact SMD can with tape packaging: φ10×10L SMD can and embossed carrier taping simplify automated assembly and inventory handling.
• Wide operating temperature span: −55°C to +125°C accommodates diverse operating environments without derating the capacitor’s core characteristics.
• Measurable leakage and loss characteristics: Specified leakage current (205 µA) and tan δ (0.12) allow precise power‑budget and thermal planning.
