RKS1J180MCNAHHGS

The RKS1J180MCNAHHGS from Nichicon is a surface‑mount conductive polymer aluminum solid electrolytic capacitor in the RKS series, offering 18 µF capacitance at a 63 V rating. It is engineered for SMD assemblies that require low ESR and high allowable ripple current in a compact radial can SMD package.

Managed for demanding thermal and lifecycle conditions, this part delivers long‑life stability (3,000 hours at 125°C) and is supplied in embossed carrier taping with moisture proof packing for automated assembly environments.

Key Features

• Capacitance & Voltage — 18 µF nominal capacitance with a rated voltage of 63 V and a tolerance of −20% to +20%.
• Low ESR — Equivalent series resistance of 40 mΩ measured at 20°C and 100 kHz, supporting efficient high‑frequency performance.
• High Ripple Current Capability — Rated ripple currents of 110 mA at 120 Hz (low frequency) and 1.1 A at 300 kHz (high frequency) for applications with significant AC stress.
• Thermal and Lifetime Performance — Rated operating temperature range −55°C to +125°C with a load life endurance of 3,000 hours at 125°C.
• Dielectric Loss — Tangent of loss angle (tan δ) specified at 0.12 (measured at 20°C, 120 Hz), useful for evaluating dissipation in your design.
• Leakage Current — Leakage current specified at 100 µA (after two minutes at rated voltage or per datasheet conditioning), aiding predictable standby and bias behavior.
• SMD Can Package — Radial, can‑style SMD package with dimensions φ8 × 8.7 mm and recommended land size L: 8.3 × W: 8.3 mm, optimized for automated placement and reflow.
• Reflow Compatibility — Designed for lead‑free reflow processes; withstands peak solder temperatures up to 260°C per the datasheet soldering profile.
• Packaging for Production — Supplied in embossed carrier taping with moisture‑proof packing to support high‑volume pick‑and‑place assembly.

Typical Applications

• High‑ripple power stages — Use where low ESR and high allowable ripple current are required to stabilize supply rails under fluctuating loads.
• Compact SMD power assemblies — Suited for space‑constrained boards that require radial can SMD capacitors with good thermal endurance.
• Elevated temperature environments — Applicable where operation across −55°C to +125°C and extended life at high temperature are necessary.

Unique Advantages

• Predictable high‑frequency behavior: Low ESR (40 mΩ at 100 kHz) and specified tan δ support stable AC performance in high‑frequency circuits.
• High ripple tolerance: Rated ripple currents (110 mA @120 Hz and 1.1 A @300 kHz) reduce thermal stress and improve lifetime in ripple‑heavy applications.
• Extended high‑temperature lifetime: 3,000 hours at 125°C provides a clear reliability baseline for thermal designs requiring long‑term operation.
• Manufacturing ready: Embossed carrier taping with moisture proof packing and compatibility with 260°C peak reflow simplifies integration into automated SMT lines.
• Compact radial SMD form factor: φ8 × 8.7 mm package offers a small footprint while delivering 63 V rated capability for dense power layouts.
