RPA1D561MCN1GS

The RPA1D561MCN1GS is a surface‑mount conductive polymer aluminum solid electrolytic capacitor in Nichicon's RPA series. It delivers 560 µF capacitance at a 20 V rating with low ESR and high ripple current capability, packaged in a compact φ10 × 12.4 mm SMD can.

Designed for general‑purpose power applications, this polarized SMD capacitor provides robust performance across a wide temperature range (‑55°C to 105°C) and a rated endurance of 2000 hours at 105°C, making it suited to compact board‑level power filtering and decoupling where reliable bulk capacitance and low losses are required.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a rated voltage of 20 V and tolerance of ‑20% to +20% at 120 Hz, 20°C.
• Conductive Polymer Aluminum Construction — Solid electrolyte design for stable electrical characteristics and low loss tangent (tanδ = 0.1 at 20°C, 120 Hz).
• Low ESR — ESR of 20 mΩ measured at 20°C / 100 kHz, enabling efficient high‑frequency decoupling and reduced heat generation.
• High Ripple Current Capability — Low‑frequency ripple current of 310 mA (120 Hz) and high‑frequency ripple current of 3.1 A (300 kHz) for demanding power stages.
• Leakage Current Specification — Leakage current of 2240 µA (measured per datasheet condition after 2 minutes at 20°C), supporting predictable bias behavior in power circuits.
• Reliability & Lifetime — Rated for 2000 hours at 105°C, with category temperature range from ‑55°C to 105°C for extended operational stability.
• Surface‑Mount Packaging — φ10 × 12.4 mm radial can in SMD form factor; supplied in embossed carrier taping with moisture proof packing for reflow assembly.
• RoHS Compliant — Environmental compliance indicated for restricted substances.

Typical Applications

• Power Supply Bulk Filtering — 560 µF at 20 V provides bulk energy storage and smoothing on compact DC power rails.
• Point‑of‑Load Decoupling — Low ESR (20 mΩ at 100 kHz) and high high‑frequency ripple capability support decoupling at switching converters and regulators.
• General‑Purpose Surface‑Mount Designs — Polarized SMD can designed for board‑level integration where compact bulk capacitance and robust thermal endurance are required.

Unique Advantages

• Compact high‑capacitance SMD package — φ10 × 12.4 mm can delivers 560 µF in a small footprint to save board area without sacrificing capacitance.
• Predictable high‑frequency performance — ESR specified at 100 kHz (20 mΩ) and ripple current data across frequencies enable easier thermal and ripple budgeting.
• Wide operating temperature range — Rated from ‑55°C to 105°C to maintain performance across harsh ambient conditions.
• Long endurance at elevated temperature — 2000 hours at 105°C supports designs targeting prolonged high‑temperature operation.
• Assembly‑friendly packaging — Supplied in embossed carrier taping with moisture proof packing for automated surface‑mount assembly and handling.
• Standards‑oriented measurements — Loss tangent, ESR, and leakage current values are provided with measurement conditions (20°C, specified frequencies, and post‑charge timing) for design verification.
