RKS1V180MCNAHGGS

The RKS1V180MCNAHGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon's RKS series, rated 18 µF at 35 V. It combines low ESR and high allowable ripple current with a compact radial SMD can (φ8 × 7.7 mm) for space-constrained power designs.

Engineered for applications requiring durable high-temperature operation and reliable decoupling, this part delivers long endurance (3000 hours at 125°C), low loss (tan δ 0.12 at 20°C/120 Hz), and high-frequency performance backed by specified ESR and ripple-current ratings.

Key Features

• Core Technology Conductive polymer aluminum solid electrolyte construction for stable electrical characteristics and improved ripple handling.
• Capacitance & Voltage 18 µF nominal capacitance with ±20% tolerance, rated for 35 V operation.
• Low ESR & High-Frequency Performance ESR specified at 30 mΩ (20°C, 100 kHz) and a dissipation factor (tan δ) of 0.12 at 20°C/120 Hz, supporting effective high-frequency decoupling.
• Ripple Current Capability Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz), enabling robust filtering on power rails and DC-DC outputs.
• Reliability & Endurance Rated life of 3000 hours at 125°C under rated voltage, with leakage current specified at 100 µA.
• Temperature Range Operating temperature range −55°C to +125°C for elevated-temperature applications.
• SMD Package & Assembly Radial can SMD (φ8 × 7.7 mm) supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow soldering to a 260°C peak per series specification.
• RoHS Compliant Conforms to RoHS directive requirements as noted in the product documentation.

Typical Applications

• Power Supply Decoupling Use for bulk and post-regulation decoupling where low ESR and high ripple handling improve transient response and stability.
• DC–DC Converter Outputs Suitable for smoothing and filtering on converter output rails, leveraging 1.6 A high-frequency ripple capability and low ESR.
• High-Frequency Power Rails Applied where compact SMD capacitors are required to suppress high-frequency noise and provide local energy storage.
• Industrial Electronics Ideal for compact control and power modules operating across a wide temperature range (−55°C to +125°C) and requiring extended endurance.

Unique Advantages

• High ripple tolerance: The combination of 1.6 A high-frequency ripple rating and 30 mΩ ESR at 100 kHz helps reduce voltage ripple on sensitive rails.
• Extended high-temperature life: 3000 hours at 125°C provides design margin for elevated-temperature installations and long-term reliability.
• Compact SMD form factor: φ8 × 7.7 mm radial SMD can allows space-efficient placement while maintaining robust capacitance and performance.
• Low loss for efficient filtering: tan δ of 0.12 (20°C/120 Hz) contributes to lower dissipation in filtering and decoupling applications.
• Reflow-compatible packaging: Supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow profiles up to 260°C for surface-mount assembly.
• Measured, verifiable performance: Key parameters (ESR, ripple current, leakage, endurance) are specified and testable to support engineering validation.
