RDS0J181MCNAFEGS

The RDS0J181MCNAFEGS is a conductive polymer aluminum solid electrolytic capacitor in Nichicon’s RDS series, delivering 180 µF at 6.3 V in a compact surface-mount can. It combines high capacitance and low ESR with high ripple-current capability to support power filtering and energy smoothing in space-constrained assemblies.

Designed for high-temperature environments, this part offers a rated operating range of –55 °C to +125 °C and a rated load life of 3000 hours at 125 °C. The SMD package is compatible with lead‑free reflow soldering (260 °C peak) and is RoHS compliant.

Key Features

• Electrical Performance — 180 µF nominal capacitance at 6.3 V with ±20% tolerance, suitable for bulk decoupling and energy storage in compact circuits.
• Low ESR — ESR of 25 mΩ measured at 100 kHz (20 °C), helping reduce AC voltage drop and heat generation at switching frequencies.
• High Ripple Current — Rated ripple current of 105 mA at 120 Hz and 1.05 A at 300 kHz, enabling robust handling of both low‑ and high‑frequency ripple in power converters.
• High-Temperature Endurance — Load life of 3000 hours at 125 °C under rated voltage, supporting extended operation in elevated-temperature applications.
• Surface-Mount Can Package — SMD radial can with dimensions φ6.3 × 5.7 mm and recommended land pattern 6.5 × 6.5 mm, enabling compact PCB layouts.
• Manufacturing Compatibility — Compatible with lead‑free reflow soldering conditions up to a 260 °C peak, easing integration into standard SMT assembly flows.
• Environmental Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply output filtering — High capacitance and low ESR make this capacitor suitable for smoothing and filtering outputs of DC‑DC converters and switching regulators.
• High-frequency switching supplies — Rated ripple current of 1.05 A at 300 kHz supports handling of high-frequency ripple in compact power stages.
• Compact industrial electronics — Small SMD can (6.3 × 5.7 mm) and wide operating temperature range (–55 °C to +125 °C) fit dense boards and elevated‑temperature industrial environments.
• Energy buffering for communication modules — The combination of capacitance and low ESR provides short-term energy storage for transient loads in modular electronics.

Unique Advantages

• High capacitance in a small footprint: 180 µF in a φ6.3 × 5.7 mm SMD can reduces board area compared with larger through-hole options.
• Low AC losses at switching frequencies: 25 mΩ ESR at 100 kHz minimizes dissipated power during high-frequency operation.
• Designed for high ripple environments: Specified ripple currents at 120 Hz and 300 kHz allow predictable thermal and electrical performance in both line-frequency and switching scenarios.
• Proven high-temperature reliability: 3000 hours rated life at 125 °C supports long-term use in elevated-temperature designs.
• SMT-friendly assembly: Lead‑free reflow compatibility (260 °C peak) aligns with modern lead‑free manufacturing processes.
• Regulatory compliance: RoHS conformity supports product-level environmental requirements.
