RKS1J220MCNAHHGS

The RKS1J220MCNAHHGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in the Nichicon RKS series. It delivers 22 µF at 63 V in a compact radial can SMD package (φ8 × 8.7 mm) optimized for applications requiring low ESR, high allowable ripple current and elevated-temperature endurance.

Designed for SMD assembly, the part supports lead‑free reflow soldering profiles and offers long-term stability with a rated operating range of −55 °C to 125 °C and a 3000‑hour endurance at 125 °C.

Key Features

• Core Electricals: 22 µF nominal capacitance with tolerance ±20% (−20% to 20%) and a rated voltage of 63 V, providing stable capacitance for mid‑voltage applications.
• Low Loss / High Ripple Capability: ESR of 40 mΩ measured at 20 °C/100 kHz and a high‑frequency ripple current of 1.1 A (at 300 kHz), plus a low‑frequency ripple rating of 110 mA (at 120 Hz), enabling effective smoothing in high‑ripple environments.
• Leakage and Dissipation: Specified leakage current of 100 µA and tangent of loss angle (tan δ) of 0.12 (measured at 20 °C, 120 Hz), supporting predictable loss and leakage behavior.
• High‑Temperature Endurance: Rated for −55 °C to 125 °C with a load life of 3000 hours at 125 °C, maintaining capacitance, tan δ and ESR within defined limits after endurance testing.
• SMD Package and Assembly: Radial, can‑style SMD package (φ8 × 8.7 mm, surface mount land 8.3 × 8.3 mm) supplied in embossed carrier taping with moisture‑proof packing for automated assembly.
• Reflow Compatibility: Compatible with lead‑free reflow soldering up to a 260 °C peak per the series soldering specification, enabling modern SMT processes.
• RoHS Compliance: Series documentation indicates compliance with the RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• SMD high‑ripple current circuits — Low ESR and a 1.1 A high‑frequency ripple rating make this part suited where sustained ripple handling in an SMD form factor is required.
• Elevated‑temperature systems — Continuous operation up to 125 °C and a 3000‑hour load life at that temperature support designs exposed to high ambient or internal heating.
• Surface‑mount assemblies requiring lead‑free reflow — Package and soldering specifications support automated SMT lines and lead‑free reflow processes.

Unique Advantages

• Low ESR for improved ripple performance: 40 mΩ ESR at 100 kHz reduces voltage drop and heating under high‑frequency ripple loads.
• High ripple current capability: 1.1 A at 300 kHz and 110 mA at 120 Hz enable robust filtering and smoothing in demanding AC and switching environments.
• Extended high‑temperature life: 3000 hours at 125 °C provides long‑term reliability in thermally stressed designs.
• SMD radial can with tape packaging: Compact φ8 × 8.7 mm package and embossed carrier taping simplify placement and board‑level integration.
• Predictable leakage and dissipation: Specified leakage current (100 µA) and tan δ (0.12) support accurate power and thermal budgeting.
• Lead‑free reflow compatibility: Support for 260 °C peak reflow enables use in modern assembly processes without special soldering handling.
