RPS0G681MCN1GS

The RPS0G681MCN1GS is a surface-mount conductive polymer aluminum electrolytic capacitor delivering 680 µF at a 4 V rating. It combines a compact φ10×7.7 mm SMD can package with low ESR and high ripple-current capability for space-constrained power designs.

Engineered for general-purpose power applications, this device offers a wide operating temperature range from −55°C to +105°C, an endurance rating of 2000 hours at 105°C, and packaging suited for automated assembly (embossed carrier taping with moisture-proof packing).

Key Features

• Capacitance and Tolerance — 680 µF nominal capacitance with tolerance −20% to +20% (specified at 120 Hz, 20°C).
• Low ESR — ESR of 22 mΩ measured at 20°C/100 kHz, supporting efficient power delivery and reduced dissipation in high-frequency circuits.
• High Ripple Current — High-frequency ripple current capability of 3.8 A (at 300 kHz) and low-frequency ripple current of 380 mA (at 120 Hz), enabling stable operation under dynamic loads.
• Loss Angle — tanδ of 0.12 (measured at 20°C, 120 Hz) for predictable AC behavior in filtering and decoupling applications.
• Robust Thermal and Lifetime Performance — Rated operating range −55°C to +105°C with an endurance (load life) of 2000 hours at 105°C.
• SMD Can Package — φ10×7.7 mm can-style SMD package (radial can - SMD) with surface-mount land size and embossed carrier taping / moisture-proof packing for automated PCB assembly.
• Reflow Compatible — Designed to tolerate lead-free reflow soldering peak conditions up to 260°C per the series specification.
• RoHS Compliant — Meets RoHS requirements as specified in the product data.

Typical Applications

• Power supply decoupling and bulk smoothing — Provides bulk capacitance and low ESR to stabilize voltage rails in compact SMD power supplies and regulators.
• High-frequency switching circuits — Supports high-frequency ripple (3.8 A at 300 kHz) for switching converters and synchronous regulators.
• General-purpose embedded power — Suitable for embedded systems requiring robust temperature range (−55°C to +105°C) and a 2000-hour endurance at elevated temperature.

Unique Advantages

• Compact high-capacitance SMD solution: 680 µF in a φ10×7.7 mm can saves board area while delivering substantial bulk energy storage.
• Low dissipation under high-frequency load: 22 mΩ ESR at 100 kHz reduces power loss and thermal rise in high-speed switching environments.
• High ripple capability: 3.8 A HF ripple rating helps maintain voltage stability in converters and filters under dynamic current demands.
• Wide temperature and proven endurance: −55°C to +105°C range with 2000 hours life at 105°C provides predictable performance in thermally demanding applications.
• Assembly-friendly packaging: Embossed carrier tape with moisture-proof packing supports automated pick-and-place and reflow processes.
• Measured and specified electrical parameters: Tangent of loss angle (tanδ 0.12 at 120 Hz) and leakage current specified to aid predictable circuit design and verification.
