RKS1V220MCNAHFGS

The RKS1V220MCNAHFGS from Nichicon is a surface‑mount conductive polymer aluminum solid electrolytic capacitor in the RKS series. It provides 22 µF capacitance at a 35 V rating with low ESR and high allowable ripple current for compact power and high‑frequency SMD designs.

Designed for applications that demand high temperature endurance and stable high‑frequency performance, this φ8 × 6.7 mm radial can SMD package delivers 3000 hours of load life at 125°C and RoHS‑compliant construction for reliable long‑term operation.

Key Features

• Electrical Performance — 22 µF capacitance at 35 V with ±20% tolerance; tanδ (DF) = 0.12 measured at 20°C, 120 Hz for predictable AC behavior.
• Low ESR & High Ripple Handling — ESR 30 mΩ at 20°C/100 kHz and high‑frequency ripple current rating of 1.6 A (300 kHz), supporting high‑frequency decoupling and power stages.
• Leakage Current — Rated leakage current of 100 µA, suitable for power‑sensitive circuits requiring low stand‑by loss.
• Thermal Endurance — Operating temperature range −55°C to +125°C with a rated life of 3000 hours at 125°C, enabling use in elevated temperature environments.
• Robust SMD Package — Compact φ8 × 6.7 mm radial can (SMD) package with recommended land size 8.3 × 8.3 mm and embossed carrier taping with moisture‑proof packing for SMT assembly.
• Soldering Compatibility — Designed for lead‑free reflow soldering (peak temperature compatibility noted in series datasheet), facilitating modern assembly processes.
• Regulatory — RoHS compliant.

Typical Applications

• High‑frequency power rails — Use where low ESR and strong high‑frequency ripple current capability are required for stable voltage filtering.
• Switching power supplies and converters — Suitable for SMD implementations that need durable capacitors with high ripple tolerance and elevated temperature life.
• Power management modules — Compact radial can SMD form factor and low leakage support space‑constrained power subsystem designs.

Unique Advantages

• High ripple tolerance: 1.6 A at 300 kHz and 160 mA at 120 Hz ratings reduce the need for parallel components in high‑frequency designs.
• Low ESR for improved transient response: 30 mΩ at 100 kHz helps maintain low impedance across switching frequencies.
• Extended high‑temperature life: 3000 hours at 125°C provides predictable end‑of‑life behavior for designs exposed to elevated temperatures.
• SMT‑friendly packaging: Embossed carrier taping and moisture‑proof packing streamline automated assembly and storage.
• Compact radial can form: φ8 × 6.7 mm footprint balances capacitance and board space for dense layouts.
