RPA1A331MCN1GS

The RPA1A331MCN1GS is a conductive polymer aluminum solid electrolytic surface-mount capacitor offering 330 µF capacitance at a 10 V rating. It delivers low ESR and high ripple capability in a compact φ10 × 7.7 mm SMD can, targeted for general-purpose surface-mount power designs.

Key value comes from a combination of low equivalent series resistance (20 mΩ at 20°C/100 kHz), high high‑frequency ripple current (3.6 A at 300 kHz), a wide operating temperature range (−55°C to +105°C), and endurance rated to 2000 hours at 105°C—providing measurable performance for power filtering and decoupling in compact assemblies.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with ±20% tolerance and a rated voltage of 10 V.
• Low ESR — 20 mΩ equivalent series resistance measured at 20°C/100 kHz for lower loss and improved high‑frequency performance.
• High Ripple Handling — Low‑frequency ripple current 360 mA (120 Hz) and high‑frequency ripple current 3.6 A (300 kHz) to support demanding ripple environments.
• Leakage & Loss — Specified leakage current of 660 µA and a tangent of loss angle (tan δ) of 0.12 (measured at 20°C, 120 Hz).
• Temperature & Endurance — Operating range −55°C to +105°C with a rated life/ endurance of 2000 hours at 105°C.
• Package & Mounting — Surface mount radial can (φ10 × 7.7 mm) in embossed carrier tape with moisture‑proof packing; compatible with lead‑free reflow peak 260°C per series data.
• Compliance — RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk decoupling and smoothing where 330 µF and a 10 V rated part are required for board-level power rails.
• High-frequency rail stabilization — Low ESR (20 mΩ @100 kHz) and high ripple current capability (3.6 A @300 kHz) for switching regulator output stabilization and high‑frequency noise suppression.
• Compact SMD assemblies — Small φ10 × 7.7 mm can package suitable for space‑constrained surface‑mount designs and automated placement.

Unique Advantages

• Measurable low-loss performance: 20 mΩ ESR at 100 kHz reduces I²R losses and improves efficiency in high‑frequency circuits.
• High ripple tolerance: 3.6 A ripple rating at 300 kHz supports demanding switching power supplies and converters.
• Wide operating temperature: −55°C to +105°C enables consistent behavior across industrial temperature ranges.
• Designed endurance: 2000 hours at 105°C provides a defined lifetime metric for thermal stress planning.
• SMD-ready packaging: Embossed carrier tape with moisture‑proof packing and lead‑free reflow compatibility simplifies assembly and storage.
• Standards compliance: RoHS compliance aligns with common environmental requirements.
