RKS1V180MCNAHFGS

The RKS1V180MCNAHFGS is a surface-mount conductive-polymer aluminum electrolytic capacitor designed for high-ripple, high-temperature applications. It delivers 18 µF capacitance at a 35 V rating with low ESR and a load-life specification of 3000 hours at 125°C.

Built for compact SMD assemblies, this radial can package combines high allowable ripple current and low loss (tanδ) to support demanding power-decoupling and smoothing roles across industrial and telecom electronics where elevated operating temperature and long-term reliability are required.

Key Features

• Electrical Performance: 18 µF capacitance with ±20% tolerance and a rated voltage of 35 V, offering a stable energy-storage element for power designs.
• Low Loss / Low ESR: tanδ of 0.12 (20°C, 120 Hz) and ESR of 30 mΩ at 20°C / 100 kHz, reducing dissipation in high-frequency and high-current circuits.
• High Ripple Current Capability: Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz), suitable for smoothing and decoupling in switching power stages.
• Extended High-Temperature Endurance: Rated for operation from −55°C to 125°C with a life/endurance of 3000 hours at 125°C, supporting elevated-temperature system deployments.
• Leakage and Reliability: Leakage current specified at 100 µA and endurance characteristics specified by the manufacturer to maintain capacitance, tanδ and ESR within defined limits after testing.
• SMD Radial Can Package: Compact φ8 × 6.7 mm can with surface-mount land recommendation 8.3 × 8.3 mm; supplied in embossed carrier taping and moisture-proof packing for automated assembly.
• RoHS Compliant: Manufactured to meet RoHS requirements.

Typical Applications

• Power Supply Filtering: Use as bulk or output smoothing in power supplies where low ESR and high ripple capability improve transient response and thermal behavior.
• DC–DC Converter Outputs: Suitable for decoupling and stabilization at converter outputs, leveraging low ESR and high-frequency ripple handling.
• Industrial Electronics: Designed for elevated-temperature environments and long-life operation, making it appropriate for industrial control and instrumentation modules.

Unique Advantages

• High-Temperature Reliability: 3000-hour rated life at 125°C provides predictable aging and endurance in hot-environment designs.
• High Ripple Tolerance: Specified high-frequency ripple current of 1.6 A at 300 kHz supports demanding switching applications without excessive heating.
• Low ESR and Loss: 30 mΩ ESR (100 kHz) and tanδ of 0.12 reduce power loss and improve efficiency in high-frequency circuits.
• Compact SMD Form Factor: φ8 × 6.7 mm can and embossed carrier taping simplify automated placement while saving PCB area compared with larger through-hole options.
• Manufacturing-Ready Packaging: Moisture-proof, embossed carrier tape packaging supports standard SMT assembly flows and lead‑free reflow profiles per the datasheet.
