RKS1V120MCNAFEGS

The RKS1V120MCNAFEGS from Nichicon is a surface-mount conductive polymer aluminum electrolytic capacitor in the RKS series. It delivers 12 µF capacitance at a 35 V rating with a compact φ6.3 × 5.8 mm can-style SMD package.

Designed for applications that demand low ESR and high allowable ripple current, this component combines a wide operating temperature range (−55 °C to +125 °C) and a 3000‑hour endurance at 125 °C for robust performance in thermally demanding environments.

Key Features

• Capacitance & Voltage — 12 µF nominal capacitance with a rated voltage of 35 V and tolerance of −20% to +20% at 20 °C, 120 Hz.
• Low ESR — 60 mΩ ESR measured at 20 °C / 100 kHz to support low-loss operation and better transient response in high-frequency circuits.
• High Ripple Current Capability — Rated ripple currents of 90 mA at 120 Hz and 900 mA at 300 kHz enable effective smoothing on both low- and high-frequency rails.
• High Temperature Endurance — Rated life of 3000 hours at 125 °C, with endurance specifications showing capacitance change within ±20% and ESR/tan δ within 150% of initial values after the test.
• Leakage & Loss — Leakage current specified at 100 µA and tan δ (loss tangent) of 0.12 measured at 20 °C / 120 Hz.
• SMD Package & Reflow Compatibility — Compact φ6.3 × 5.8 mm can‑style SMD with surface mount land size 6.6 × 6.6 mm; compatible with lead‑free reflow soldering up to a 260 °C peak as defined in the series datasheet.
• Packaging & Compliance — Supplied in embossed carrier taping with moisture proof packing; RoHS compliant and in mass production.

Typical Applications

• Switching Power Supplies — Output smoothing and decoupling on high-frequency converters where 900 mA HF ripple capability and low ESR (60 mΩ) improve stability and reduce voltage ripple.
• Point-of-Load Regulation — Local decoupling for DC‑DC converters and regulators in compact electronics that require a 35 V rating and reliable operation across −55 °C to +125 °C.
• Industrial Power Modules — Bulk or filtering use in power modules and control electronics that benefit from 3000‑hour endurance at elevated temperature (125 °C).

Unique Advantages

• High ripple tolerance — 900 mA high‑frequency ripple current reduces thermal stress and improves lifespan in high switching‑speed designs.
• Low ESR for improved transient response — 60 mΩ ESR at 100 kHz minimizes voltage drop and supports fast load transients.
• Extended high‑temperature life — 3000 hours at 125 °C provides predictable long-term behavior in hot operating environments.
• Compact SMD form factor — φ6.3 × 5.8 mm package and standard land pattern (6.6 × 6.6 mm) simplify board layout in space‑constrained designs.
• Lead‑free reflow compatible — Designed for lead‑free reflow profiles up to 260 °C peak to match modern assembly processes.
• RoHS compliant supply — Meets regulatory requirements for lead‑free content for global electronics manufacturing.
