RKS1J120MCNAHFGS

The RKS1J120MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in a radial can SMD package (φ8 × 6.7 mm). It provides 12 µF capacitance at a 63 V rating with a -20% to +20% tolerance and is built for applications that demand sustained performance at elevated temperatures.

Key value propositions include high ripple-current capability, low ESR, and long-term high-temperature endurance: specified ESR is 40 mΩ at 100 kHz, high-frequency ripple current up to 1.1 A (300 kHz), and a rated life of 3000 hours at 125°C. The part ships in embossed carrier taping with moisture-proof packing and is in mass production.

Key Features

• Conductive Polymer Electrolyte — Solid polymer construction for stable electrical characteristics and low ESR; tanδ is 0.12 (measured at 20°C, 120 Hz).
• Low ESR & High Ripple Handling — ESR specified at 40 mΩ (20°C, 100 kHz), with ripple current ratings of 110 mA at 120 Hz and 1.1 A at 300 kHz.
• High-Temperature Endurance — Rated lifetime of 3000 hours at 125°C; operating temperature range from −55°C to +125°C.
• Leakage Current — Specified leakage current of 100 µA (measurement condition per datasheet).
• Compact SMD Radial Can — Package size φ8 × 6.7 mm (L: 6.7 × D: 8 mm) with recommended land pattern 8.3 × 8.3 mm for surface-mount assembly.
• Assembly Compatibility — SMD type compatible with lead‑free reflow soldering (peak 260°C, reflow up to two cycles as specified in the datasheet).
• Packaging & Availability — Supplied in embossed carrier taping with moisture-proof packing; product status: mass production.

Typical Applications

• Power-supply smoothing and bulk decoupling — High ripple current rating and low ESR make this capacitor suitable for smoothing in compact power modules and supplies.
• DC‑DC converters and point-of-load filtering — Low ESR and high-frequency ripple capability support stable output filtering in converter stages.
• Industrial and telecom power systems — Long life at 125°C and robust leakage/ESR performance support use in high-temperature power electronics environments.

Unique Advantages

• High-temperature durability: 3000-hour rated life at 125°C supports sustained operation in elevated-temperature designs.
• Improved power handling: 1.1 A high-frequency ripple current rating (300 kHz) and 40 mΩ ESR enable effective handling of fast switching currents.
• Compact SMD form factor: φ8 × 6.7 mm radial can SMD package minimizes board area while delivering 12 µF at 63 V.
• Assembly-ready: Designed for lead-free reflow up to 260°C per datasheet soldering profile for straightforward SMT line integration.
• Stable electrical parameters: Specified tanδ (0.12 at 20°C/120 Hz) and controlled leakage current support predictable performance in filtering and decoupling roles.

Why Choose RKS1J120MCNAHFGS?

RKS1J120MCNAHFGS positions itself as a robust SMD conductive polymer aluminum capacitor for designs that need a compact 12 µF, 63 V solution with low ESR and high ripple-current capability. Its 3000-hour endurance at 125°C and broad operating range (−55°C to +125°C) make it appropriate for demanding power-electronics and industrial applications where thermal and electrical reliability are important.

Engineers and procurement teams benefit from a component that combines measurable electrical performance (40 mΩ ESR at 100 kHz, tanδ 0.12) with assembly-ready packaging (embossed carrier taping, moisture-proof packing), simplifying BOM selection for higher-temperature, high-ripple designs.
