RKS1E120MCNAFGGS

The RKS1E120MCNAFGGS is a conductive polymer aluminum solid electrolytic capacitor in an SMD radial can package, designed for demanding power and high-frequency decoupling applications. It delivers 12 µF capacitance at 25 V with low ESR and high allowable ripple current, offering reliable performance across a wide operating range.

With a rated temperature range of −55°C to 125°C and a 3000 hour endurance at 125°C, this component targets electronics that require stable capacitance and low-loss operation in elevated-temperature environments while supporting automated assembly through embossed carrier taping and moisture-proof packing.

Key Features

• Capacitance & Voltage — 12 µF nominal capacitance rated at 25 V with a tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• Low Loss / High Frequency Performance — Tangent of loss angle (tanδ) of 0.12 measured at 20°C, 120 Hz, and an ESR of 30 mΩ measured at 20°C, 100 kHz, enabling effective high-frequency decoupling.
• High Allowable Ripple Current — Rated ripple currents of 140 mA at 120 Hz and 1.4 A at 300 kHz support demanding power-rail smoothing and transient suppression duties.
• High-Temperature Endurance — Load life of 3000 hours at 125°C under rated voltage, providing proven stability for long-term high-temperature operation.
• Robust Operating Range — Wide operating temperature from −55°C to 125°C for use in thermally challenging environments.
• SMD Radial Can Package — Compact φ6.3 × 7.7 mm (D × L) footprint with surface-mount land size 6.6 × 6.6 mm; supplied in embossed carrier tape with moisture-proof packing for pick-and-place assembly.
• RoHS Compliant & Production Ready — Conforms to RoHS and is in mass production status for established supply availability.

Typical Applications

• Power-supply decoupling — Low ESR and high ripple current ratings make this capacitor suitable for smoothing and decoupling on regulated power rails.
• DC–DC converter output filtering — High allowable high-frequency ripple current and low loss characteristics support stable output filtering in compact converters.
• Telecom and networking equipment — Temperature endurance and long life at 125°C provide reliability for components exposed to continuous operation and elevated temperatures.
• Industrial control electronics — Wide −55°C to 125°C operating range and long load life suit control systems operating across varied thermal environments.

Unique Advantages

• Reliable high-temperature performance: 3000 hours endurance at 125°C ensures capacitance stability and controlled ESR under extended thermal stress.
• High ripple handling: 1.4 A at 300 kHz and 140 mA at 120 Hz allow tighter voltage regulation and reduced voltage ripple on power rails.
• Compact SMD form factor: φ6.3 × 7.7 mm can package with surface-mount land footprint supports space-constrained board designs and automated assembly.
• Low loss for high-frequency use: tanδ = 0.12 (20°C, 120 Hz) and 30 mΩ ESR at 100 kHz deliver efficient decoupling at switching frequencies.
• Production-ready packaging: Embossed carrier tape and moisture-proof packing streamline inventory handling and placement in volume manufacturing.
• Regulatory compliance: RoHS compliance supports deployment in regions requiring restricted substance conformity.
