RKS1D181MCNAFGGS

The RKS1D181MCNAFGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor delivering 180 µF at 20 V with low ESR and high allowable ripple current. Its combination of high capacitance in a compact φ6.3 × 7.7 mm can, wide operating temperature range (‑55 °C to 125 °C) and a rated life of 3000 hours at 125 °C makes it suited for power-dense designs that require stable decoupling and smoothing under elevated temperature and ripple stress.

Key Features

• Electrical Performance — 180 µF nominal capacitance at 20 V with capacitance tolerance −20% to +20% and tanδ of 0.12 (measured at 20 °C, 120 Hz), enabling predictable AC performance.
• Low ESR and High Ripple Handling — ESR of 30 mΩ at 20 °C / 100 kHz and high-frequency ripple current rated 1.4 A (300 kHz), supporting efficient decoupling in high-frequency power stages.
• Dual-Frequency Ripple Ratings — Low-frequency ripple current 140 mA at 120 Hz plus the 1.4 A high-frequency rating gives designers measurable allowances across common ripple environments.
• Robust Thermal Endurance — Operating range −55 °C to 125 °C and a load life of 3000 hours at 125 °C for sustained performance in elevated-temperature systems.
• SMD Package & Assembly — Compact φ6.3 × 7.7 mm radial can designed for surface-mount assembly; packaged in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow profiles up to the specified soldering conditions.
• Leakage and Reliability — Leakage current specification up to 180 µA and datasheet-backed endurance and shelf-life tests ensure predictable behavior over time and after thermal or humidity exposure.
• Compliance — RoHS compliant construction for regulatory adherence in commercial and industrial product builds.

Typical Applications

• Power Supply Filtering — Bulk and output filtering where low ESR and high ripple capability reduce voltage ripple and support stable regulation at 20 V systems.
• DC‑DC Converter Output — Output-stage decoupling for converters requiring compact, high-capacitance SMD components with measurable high-frequency ripple capacity.
• Industrial and Harsh‑Environment Electronics — Applications operating across −55 °C to 125 °C that benefit from long life (3000 h at 125 °C) and temperature-resilient capacitive performance.
• SMD Assembly for High-Reliability Boards — Surface-mount designs assembled with lead-free reflow processes that need embossed carrier taping and moisture-proof packaging for production handling.

Unique Advantages

• High Capacitance in a Small Footprint — 180 µF in a φ6.3 × 7.7 mm can minimizes board area while providing substantial energy storage for local decoupling.
• Measurable Low ESR — 30 mΩ at 100 kHz offers designers a concrete ESR baseline to size damping networks and predict thermal rise under ripple load.
• Defined Ripple Ratings at Two Frequencies — Specified ripple current at 120 Hz and 300 kHz allows selection and verification across low- and high-frequency ripple environments.
• Proven High-Temperature Endurance — 3000 hours at 125 °C provides a quantified reliability metric for designs exposed to sustained elevated temperatures.
• Production‑Friendly Packaging — Embossed carrier taping and moisture-proof packing simplify automated SMD placement and inventory handling for manufacturing.
• RoHS Compliance — Conforms to RoHS requirements for streamlined regulatory acceptance in commercial products.
