RDS1A181MCNAFEGS

The RDS1A181MCNAFEGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor providing 180 µF at 10 V in a compact φ6.3×5.7 mm can. It combines high capacitance and high ripple-current capability with a wide operating temperature range for board-level power applications.

Designed for compact, high-ripple environments, this SMD part delivers low ESR and long load life—features targeted at power conversion, filtering and decoupling applications in temperature-challenging electronics.

Key Features

• Core Electrical 180 µF nominal capacitance at a rated voltage of 10 V with tolerance of −20% to +20%.
• Low Loss / Stable Performance Tangent of loss angle (tan δ) of 0.12 measured at 20 °C, 120 Hz, supporting efficient energy transfer in AC/ripple conditions.
• Low ESR, High Ripple Capacity Equivalent series resistance of 25 mΩ measured at 100 kHz and rated ripple currents of 180 mA at 120 Hz and 1.8 A at 300 kHz for demanding ripple environments.
• Thermal and Endurance Rated for operation from −55 °C to +125 °C with a load life of 3000 hours at 125 °C, enabling sustained performance under elevated temperatures.
• Leakage and Reliability Leakage current specified at 700 µA (after 2 minutes at 20 °C) with endurance limits defined—capacitance, tan δ and ESR remain within specified margins after life test.
• Package and Assembly Compact φ6.3×5.7 mm SMD can (package case radial, can - SMD) supplied in embossed carrier taping with moisture-proof packing; compatible with lead‑free reflow up to 260 °C peak.
• Regulatory RoHS compliant.

Typical Applications

• Power-supply bulk decoupling — Provides energy storage and smoothing in compact DC‑DC converters and power modules where high ripple current capability is required.
• High-frequency filtering — Low ESR and specified ripple performance at 100–300 kHz make it suitable for board-level HF filtering and stabilization.
• Embedded and compact systems — Small φ6.3×5.7 mm SMD package fits space-constrained designs needing substantial capacitance at 10 V.
• Industrial electronics operating at elevated temperature — Rated to −55 °C to +125 °C with a 3000‑hour life at 125 °C for prolonged high-temperature operation.

Unique Advantages

• High ripple-current capability: Rated ripple current up to 1.8 A at 300 kHz and 180 mA at 120 Hz, reducing temperature rise under dynamic loads.
• Low ESR for improved power efficiency: 25 mΩ at 100 kHz supports lower conduction losses and tighter voltage regulation in power stages.
• Compact SMD can: φ6.3×5.7 mm form factor delivers high capacitance in a PCB-friendly surface-mount package.
• Long high-temperature life: 3000 hours at 125 °C provides predictable endurance for designs exposed to sustained elevated temperatures.
• Assembly-ready packaging: Embossed carrier taping with moisture-proof packing and compatibility with 260 °C lead‑free reflow simplify manufacturing integration.
• Verified leakage performance: Leakage current spec of 700 µA at 20 °C with clear post-test conditions for reliable margining in designs.
