RKS1V181MCNAJJGS

The RKS1V181MCNAJJGS is a surface-mount conductive polymer aluminum electrolytic capacitor in the Nichicon RKS series, specified at 180 µF and 35 V. It combines high capacitance in a compact φ10 × 10 mm SMD can with low ESR and high allowable ripple current to address general-purpose power applications that require robust filtering and energy buffering.

Designed for SMD assembly with embossed carrier taping and moisture-proof packing, this part offers a wide operating temperature range of −55 °C to 125 °C and a rated life of 3000 hours at 125 °C, delivering reliable performance in high-temperature environments.

Key Features

• Capacitance and Voltage — 180 µF nominal capacitance with a 35 V rated voltage and capacitance tolerance of −20% to +20%.
• Low ESR — Equivalent series resistance of 20 mΩ measured at 20 °C / 100 kHz for improved power delivery and reduced losses.
• High Ripple Handling — Low-frequency ripple current of 200 mA (120 Hz) and high-frequency ripple current of 2.0 A (300 kHz) to support demanding power circuits.
• Solid Polymer Electrolyte — Conductive polymer construction for stable performance, low loss (tanδ = 0.12 at 20 °C, 120 Hz) and controlled leakage (315 µA).
• High Temperature Endurance — Load life rated 3000 hours at 125 °C, with endurance limits for capacitance, tanδ and ESR defined by the RKS series specifications.
• SMD Can Package & Assembly — φ10 × 10 mm radial can in an SMD package with embossed carrier taping and moisture-proof packing; compatible with lead-free reflow soldering conditions (260 °C peak).
• Wide Operating Range — Specified for −55 °C to +125 °C operation to suit elevated-temperature board-level environments.
• Regulatory Compliance — RoHS compliant per provided product data.

Typical Applications

• General-purpose power decoupling — Use for board-level smoothing and decoupling where 180 µF capacitance, low ESR (20 mΩ) and a 35 V rating are required.
• High-ripple power rails — Suitable for circuits that demand high ripple handling thanks to 2.0 A high-frequency ripple current capability (300 kHz).
• Elevated-temperature systems — Fits applications needing sustained performance at up to 125 °C, supported by a 3000‑hour life rating at that temperature.

Unique Advantages

• High capacitance in a compact SMD can: 180 µF in a φ10 × 10 mm package minimizes board area for bulk energy storage.
• Low loss and low ESR: 20 mΩ ESR and tanδ of 0.12 reduce power dissipation and improve efficiency in high-frequency power paths.
• High ripple capability: 2.0 A at 300 kHz and 200 mA at 120 Hz let designers handle both high- and low-frequency ripple conditions.
• Robust thermal endurance: Rated for −55 °C to 125 °C with a 3000‑hour life at 125 °C for sustained reliability in hot environments.
• Assembly-ready packaging: Embossed carrier taping and moisture-proof packing streamline automated SMD processes and storage.
• Regulatory alignment: RoHS compliance supports environmentally conscious manufacturing requirements.
