RKS1H220MCNAHGGS

The RKS1H220MCNAHGGS is a Nichicon RKS series conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount can. It provides 22 µF capacitance at 50 V with low ESR and high allowable ripple current, designed for board-level power applications that require robust performance at elevated temperatures.

Key value propositions include low equivalent series resistance (30 mΩ at 100 kHz), high-frequency ripple handling (up to 1.6 A at 300 kHz), and long endurance (3000 hours at 125°C), all in an SMD package compatible with lead-free reflow processes.

Key Features

• Conductive polymer aluminum solid construction — Solid electrolyte design for stable performance and high-frequency response.
• Capacitance & tolerance — 22 µF with tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Voltage rating — Rated for 50 V DC operation.
• Low ESR — 30 mΩ specified at 20°C / 100 kHz to minimize voltage drop and internal heating in power circuits.
• High ripple current capability — 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) for demanding ripple environments.
• High-temperature endurance — Rated life of 3000 hours at 125°C, supporting long-term operation in elevated-temperature environments.
• Leakage and dissipation characteristics — Leakage current specified at 100 µA and tanδ (loss tangent) of 0.12 (20°C, 120 Hz).
• SMD package & assembly-ready — φ8 × 7.7 mm can-style SMD (radial can - SMD) with embossed carrier taping and moisture-proof packing; compatible with lead-free reflow to a 260°C peak.
• RoHS compliant — Conforms to RoHS requirements as specified in the product documentation.

Typical Applications

• High-ripple power rails — Input/output decoupling in power converters where the 1.6 A high-frequency ripple current rating and 30 mΩ ESR reduce voltage ripple and heat generation.
• Elevated-temperature power modules — Power assemblies and modules that require stable capacitance and long life at temperatures up to 125°C (3000 h endurance at rated conditions).
• SMD power assemblies — Surface-mount designs needing a compact, reflow-compatible aluminum polymer capacitor delivered in embossed carrier taping for automated placement.

Unique Advantages

• Low ESR for reduced loss: 30 mΩ at 100 kHz lowers internal dissipation and helps maintain voltage stability in high-frequency circuits.
• Strong ripple handling: High-frequency ripple rating of 1.6 A supports demanding switching supplies and DC-DC converters.
• Extended high-temperature life: 3000 hours at 125°C offers long-term reliability in thermally stressed applications.
• Reflow-ready SMD form factor: φ8 × 7.7 mm SMD can with lead-free reflow compatibility (260°C peak) simplifies surface-mount assembly and automated manufacturing.
• Controlled leakage and dielectric loss: Leakage current specified at 100 µA and tanδ of 0.12 (20°C, 120 Hz) enable predictable behavior in power circuits.
• Supply-chain friendly packaging: Embossed carrier taping and moisture-proof packing streamline handling and placement for volume production.
