RKS1J180MCNAHGGS

The RKS1J180MCNAHGGS is a surface-mount conductive polymer aluminum electrolytic capacitor designed for high-temperature operation and high ripple-current applications. It delivers 18 µF capacitance at a 63 V rating with low ESR and long endurance, making it suitable for demanding board-level power decoupling and filtering in thermally stressed environments.

Packaged in an SMD radial can (φ8 × 7.7 mm) and supplied in embossed carrier taping with moisture-proof packing, this part supports lead‑free reflow processes and is RoHS compliant.

Key Features

• Capacitance & Voltage — 18 µF capacitance with a rated voltage of 63 V and capacitance tolerance of -20% to +20%.
• Low Loss & ESR — tanδ (DF) = 0.12 (measured at 20°C, 120 Hz) and ESR = 40 mΩ (measured at 20°C, 100 kHz), supporting efficient AC performance.
• High Ripple Current Capability — Low-frequency ripple current 110 mA (120 Hz) and high-frequency ripple current 1.1 A (300 kHz) for robust handling of switching currents.
• Leakage & Polarization — Leakage current specified at 100 µA; polarized construction for correct orientation in DC circuits.
• High-Temperature Endurance — Rated operating temperature range from -55°C to +125°C with a load-life specification of 3000 hours at 125°C.
• Surface-Mount Package — Radial can SMD package (φ8 × 7.7 mm) with recommended land pattern L: 8.3 × W: 8.3 mm; compatible with lead‑free reflow up to 260°C peak.
• Packaging & Compliance — Supplied in embossed carrier taping / moisture-proof packing and compliant with RoHS requirements.

Typical Applications

• Power supply decoupling — Low ESR and high ripple-current ratings make this capacitor suitable for board-level decoupling in power-regulation circuits operating at elevated temperatures.
• Switching regulator output filtering — High-frequency ripple current capability and low loss tangent support stable filtering at switching frequencies.
• Industrial electronics — Long life at 125°C (3000 hours) and wide operating temperature range address thermal stress in industrial power modules and control electronics.

Unique Advantages

• High-temperature reliability: Rated for -55°C to +125°C with a 3000-hour life at 125°C, enabling sustained operation in hot environments.
• Superior AC performance: Low tanδ and 40 mΩ ESR at 100 kHz reduce loss and heat generation under AC ripple.
• Robust ripple handling: 1.1 A high-frequency ripple current rating supports modern switching power architectures.
• SMD convenience with reflow compatibility: Radial can SMD form factor and lead‑free reflow compatibility (up to 260°C peak) simplify automated assembly.
• Ready-to-use packaging: Embossed carrier taping with moisture‑proof packing eases surface-mount assembly and storage.
• Regulatory compliance: RoHS‑compliant construction aligns with environmental requirements.
