RKS1E180MCNAFGGS

The RKS1E180MCNAFGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It delivers 18 µF at 25 V in a compact φ6.3 × 7.7 mm radial can SMD package designed for applications requiring low ESR and elevated temperature endurance.

Engineered for high ripple-current and high-frequency use, this part is suited to power delivery and filtering roles where tight thermal and electrical performance are required, backed by a 3000-hour rated life at 125°C.

Key Features

• Capacitance & Tolerance: 18 µF nominal capacitance with tolerance of -20% to +20% (±20% at 120 Hz, 20°C).
• Rated Voltage & Polarization: 25 V rated voltage; polarized electrolytic design for DC power applications.
• Low ESR & High-Frequency Performance: ESR specified at 30 mΩ (20°C, 100 kHz) to minimize loss at switching and high-frequency conditions; high-frequency ripple current rating of 1.4 A at 300 kHz.
• Ripple Handling: Low-frequency ripple current of 140 mA at 120 Hz and high-frequency ripple capability of 1.4 A at 300 kHz for robust filtering under dynamic loads.
• Temperature & Endurance: Operating range from -55°C to +125°C with rated load life of 3000 hours at 125°C.
• Package & Mounting: Surface-mount radial can (φ6.3 × 7.7 mm) with recommended land size 6.6 × 6.6 mm; supplied in embossed carrier tape with moisture-proof packing for SMT assembly.
• Leakage & Dissipation: Leakage current specified at 100 µA and loss tangent (tan δ) of 0.12 measured at 20°C, 120 Hz.
• Regulatory Compliance: RoHS compliant.

Typical Applications

• Power supply filtering: Low ESR and high ripple-current capability make this capacitor suitable for bulk and output filtering in DC power rails.
• High-frequency decoupling: ESR specified at 100 kHz and high-frequency ripple rating support decoupling in switching converter stages operating into the 100–300 kHz range.
• Industrial and high-temperature electronics: Rated operation to 125°C with 3000-hour endurance targets designs exposed to elevated ambient temperatures.
• SMD high-current modules: Surface-mount radial can and embossed carrier taping facilitate automated placement in compact power modules and assemblies that require high allowable ripple current.

Unique Advantages

• High ripple-current tolerance: 1.4 A at 300 kHz and 140 mA at 120 Hz reduce heating and improve reliability in dynamic power systems.
• Low ESR chemistry: 30 mΩ ESR at 100 kHz lowers AC loss and supports efficient high-frequency operation.
• Extended high-temperature life: 3000-hour endurance at 125°C provides predictable long-term performance in hot environments.
• Compact SMD radial can: φ6.3 × 7.7 mm footprint balances capacitance and board space for area-constrained designs.
• Manufacturing-ready packaging: Embossed carrier taping with moisture-proof packing supports high-temperature reflow processes and automated assembly flows.
• Clear electrical limits: Specified leakage (100 µA) and tan δ (0.12 at 120 Hz, 20°C) enable straightforward design verification and margining.
