RPS1E331MCNASQGS

The RPS1E331MCNASQGS from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount (SMD) can-style package. It provides 330 µF capacitance at 25 V with a low ESR construction and high ripple-current capability, targeted for general-purpose power electronics applications.

Designed for demanding thermal and ripple environments, this device delivers a combination of low loss (tanδ 0.08 at 20°C, 120 Hz), high frequency performance, and a long rated life of 5000 hours at 105°C.

Key Features

• Capacitance & Voltage: 330 µF rated capacitance with a 25 V rated voltage and tolerance of -20% to +20% for predictable energy storage.
• Low Loss / High Frequency Performance: tanδ = 0.08 (20°C, 120 Hz) and ESR = 14 mΩ measured at 20°C/100 kHz, supporting efficient high-frequency decoupling and filtering.
• High Ripple Current Capacity: Low-frequency ripple current 500 mA (120 Hz) and high-frequency ripple current 5 A (300 kHz) for robust handling of AC stress on power rails.
• Thermal and Endurance Rating: Operating temperature range −55°C to +105°C with a load life specification of 5000 hours at 105°C.
• Surface-Mount Can Package: φ10 × 12.4 mm can-style SMD package (size L: 1.24 cm × D: 1.00 cm) suitable for automated assembly; supplied in embossed carrier taping with moisture-proof packing.
• Leakage and Reliability: Leakage current rated at 1650 µA (per datasheet measurement standard), supporting predictable bias behavior after warm-up and voltage application.
• Compliance: RoHS compliant.

Typical Applications

• General-purpose power electronics: Use where a 25 V polymer aluminum SMD capacitor is required for energy storage, smoothing, or bulk decoupling in board-mounted power circuits.
• High-frequency power rails: Applicable where low ESR (14 mΩ at 100 kHz) and high-frequency ripple handling (5 A at 300 kHz) are needed to stabilize switching converter outputs.
• Thermally demanding environments: Suitable for designs operating up to 105°C with a rated endurance of 5000 hours at that temperature.

Unique Advantages

• Low ESR at high frequency: 14 mΩ (20°C/100 kHz) minimizes voltage drop and heat generation in high-speed switching applications.
• Strong ripple-current capability: Rated for 5 A at 300 kHz and 500 mA at 120 Hz, enabling reliable handling of both HF switching ripple and low-frequency fluctuations.
• Extended high-temperature life: 5000 hours at 105°C provides long-term stability for designs exposed to elevated operating temperatures.
• Compact SMD can packaging: φ10 × 12.4 mm form factor offers a high-capacitance, board-mountable solution with embossed carrier taping for assembly efficiency.
• Predictable loss characteristics: tanδ of 0.08 (20°C, 120 Hz) supports low dissipation and consistent AC performance.
