RKS1V181MCNAJLGS

The RKS1V181MCNAJLGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor in the RKS series. It provides 180 µF capacitance at a 35 V rating in a compact φ10 × 12.4 mm can-style SMD package suited for general-purpose power management.

Designed for demanding thermal and ripple conditions, this capacitor delivers low ESR and high allowable ripple current with a rated operating range of −55°C to 125°C and a rated life of 3000 hours at 125°C, making it appropriate for boards that require stable filtering and decoupling on 35 V rails.

Key Features

• Electrical Performance — 180 µF capacitance with ±20% tolerance and a tanδ (DF) of 0.12 measured at 20°C, 120 Hz for predictable AC behavior.
• Low ESR — ESR of 20 mΩ measured at 20°C/100 kHz, supporting low-loss operation and improved power delivery at high frequencies.
• High Ripple Handling — Low-frequency ripple current of 200 mA (120 Hz) and high-frequency ripple current of 2.0 A (300 kHz) for effective smoothing and decoupling of switching supplies.
• Wide Temperature & Long Life — Operating temperature range of −55°C to 125°C with a rated life of 3000 hours at 125°C for durability in thermally stressed environments.
• Surface-Mount Can Package — Radial can, SMD package (φ10 × 12.4L) optimized for automated placement; available in embossed carrier taping with moisture-proof packing for production lines.
• Leakage & Reliability — Specified leakage current of 315 µA and endurance/shelf-life characteristics consistent with long-term board reliability.
• Lead-Free Reflow Compatible — Compatible with lead-free reflow soldering conditions up to a 260°C peak per the datasheet soldering profile.
• Regulatory Status — RoHS compliant for use in lead-free manufacturing environments.

Typical Applications

• Power supply bulk filtering — Smoothing and energy storage on 35 V rails where 180 µF and low ESR help stabilize voltage under load.
• DC–DC converter output filtering — High-frequency ripple current capability and low ESR support switching regulator outputs and post-regulation decoupling.
• Industrial and consumer electronics — General-purpose decoupling and filtering in assemblies requiring wide operating temperature and extended life.
• High-frequency power modules — Use in modules and boards where 100 kHz+ performance and low loss are important for efficiency.

Unique Advantages

• Low ESR reduces thermal loss: 20 mΩ ESR at 100 kHz lowers dissipation and improves efficiency in high-frequency circuits.
• High ripple current capability: 2.0 A at 300 kHz enables effective handling of switching noise and transient currents.
• Extended high-temperature life: 3000 hours at 125°C provides durability for thermally challenging designs.
• Compact SMD can package: φ10 × 12.4 mm form factor offers a balance of capacitance and board space for automated assembly.
• Manufacturing-ready packaging: Embossed carrier taping with moisture-proof packing simplifies high-volume pick-and-place workflows.
• RoHS compliant: Conforms to lead-free manufacturing requirements for broad deployment.
