RKS1E181MCNAJLGS

The RKS1E181MCNAJLGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It delivers 180 µF capacitance at a 25 V rating in a compact φ10 × 12.4 mm can‑style SMD package.

Designed for general-purpose SMD applications that demand high-frequency performance and robust ripple handling, this part combines low ESR and high allowable ripple current with extended high-temperature endurance for reliable operation in demanding electronic power circuits.

Key Features

• Core Technology — Conductive Polymer Aluminum: Solid conductive polymer electrolyte provides stable electrical performance and supports high-frequency operation.
• Capacitance & Voltage: 180 µF capacitance with a 25 V rated voltage and tolerance of −20% to +20% at 20°C, 120 Hz.
• Low ESR & High Ripple Handling: ESR of 20 mΩ measured at 20°C/100 kHz and high-frequency ripple current rating of 2.0 A (specified at 300 kHz), supporting high ripple environments.
• Loss Tangent (tan δ): tanδ = 0.12 measured at 20°C/120 Hz for predictable dissipation characteristics in AC conditions.
• Leakage Current: Specified leakage current of 225 µA after standard conditioning, enabling low standby loss where required.
• Wide Temperature & Long Life: Rated for −55°C to +125°C with an endurance (load life) of 3000 hours at 125°C, suitable for extended high-temperature operation.
• Package & Assembly: φ10 × 12.4 mm radial can SMD (package case: Radial, Can - SMD) supplied in embossed carrier taping with moisture‑proof packing; compatible with lead-free reflow soldering (peak up to 260°C as specified for the series).
• Series Compliance: Part of the Nichicon RKS series, which is documented as compliant to the RoHS directive.

Typical Applications

• High‑frequency power circuits: Suitable where low ESR and stable high‑frequency performance are required.
• High‑ripple environments: Designed for SMD applications that require high allowable ripple current and robust ripple handling.
• General‑purpose SMD designs: Used in compact surface‑mount assemblies that benefit from conductive polymer aluminum capacitance and extended temperature capability.

Unique Advantages

• Low electrical loss: 20 mΩ ESR at 100 kHz reduces heat generation and voltage drop in high-frequency circuits.
• High ripple tolerance: 2.0 A high-frequency ripple current rating supports demanding power-stage and decoupling duties.
• Extended high-temperature endurance: 3000 hours at 125°C provides predictable lifetime performance in elevated-temperature applications.
• Compact SMD can package: φ10 × 12.4 mm form factor in an SMD-compatible can enables high capacitance in a small footprint for automated assembly.
• Manufacturing‑ready packaging: Embossed carrier taping with moisture-proof packing simplifies pick-and-place and storage handling.
• Documented RoHS compliance: Series-level compliance supports regulatory requirements for many global designs.
