RKS1D181MCNAHFGS

The RKS1D181MCNAHFGS is a surface-mount conductive polymer aluminum electrolytic capacitor delivering 180 µF at a 20 V rating. It combines high capacitance in a compact φ8 × 6.7 mm SMD can with low ESR and high allowable ripple current for demanding power electronics applications.

Designed for elevated operating temperatures, the device is specified for −55°C to 125°C with a rated life of 3000 hours at 125°C. It ships in embossed carrier taping with moisture-proof packing for automated assembly and mass-production workflows.

Key Features

• Electrical Performance — 180 µF nominal capacitance with tolerance −20% to 20% and tanδ (DF) of 0.12 measured at 20°C/120 Hz for predictable impedance behavior.
• Low ESR and High Ripple Handling — ESR of 30 mΩ at 20°C/100 kHz and high-frequency ripple current rated at 1.6 A (300 kHz), plus 160 mA at 120 Hz for robust filtering and decoupling.
• Leakage Current — Specified leakage current of 180 µA after standard conditioning to support stable bias behavior.
• Reliability & Endurance — Rated for 3000 hours life at 125°C under rated voltage, with documented endurance and damp-heat performance in the datasheet.
• Assembly-Ready SMD Package — φ8 × 6.7 mm radial can SMD package (package case: radial, can - SMD) compatible with lead-free reflow soldering profiles to 260°C peak and supplied in embossed carrier tape for pick-and-place.
• Wide Temperature Range — Operational from −55°C to 125°C to meet high-temperature board-level requirements.

Typical Applications

• Power supply decoupling — Low ESR and high ripple current capability make it suitable for bulk and output decoupling in compact power modules.
• DC–DC converter output smoothing — 180 µF capacitance and 20 V rating provide energy storage and stability for switching regulator outputs.
• Embedded and industrial electronics — Compact SMD can and extended temperature rating support space-constrained, high-reliability designs.
• High-frequency filtering — Low ESR at 100 kHz and rated high-frequency ripple current support local filtering in high-speed power systems.

Unique Advantages

• High capacitance in a compact SMD form: 180 µF in a φ8 × 6.7 mm package enables space-efficient designs without sacrificing energy storage.
• Improved thermal endurance: 3000 hours life at 125°C provides long-term stability in elevated-temperature environments.
• Robust ripple handling: 1.6 A high-frequency ripple rating and low ESR (30 mΩ) reduce voltage ripple and thermal stress on the capacitor.
• Reflow-compatible packaging: SMD can design and embossed carrier taping support automated assembly and lead-free reflow processes to 260°C peak.
• Predictable electrical behavior: Specified tanδ, leakage current, and tolerance values allow accurate margining in power and filtering designs.
