RPS0J681MCN1GS

The RPS0J681MCN1GS is a surface-mount conductive polymer aluminum electrolytic capacitor from Nichicon’s RPS series, offering 680 µF capacitance at a 6.3 V rating. It combines low ESR and high ripple-current capability in a compact φ10 × 12.4 mm SMD can for general-purpose electronic designs.

This part is specified for operation from −55°C to 105°C with a rated load life of 2000 hours at 105°C, RoHS compliance, and embossed carrier taping with moisture-proof packing for automated assembly.

Key Features

• Capacitance and Voltage: 680 µF nominal capacitance with a rated voltage of 6.3 V and tolerance of −20% to +20%.
• Low Loss (DF): Tangent of loss angle (tan δ) = 0.15 measured at 20°C, 120 Hz, supporting stable AC performance.
• Low ESR for High-Frequency Use: ESR = 13 mΩ at 20°C/100 kHz, enabling effective high-frequency filtering and power decoupling.
• High Ripple Current Capability: Rated ripple current up to 520 mA at 120 Hz (low frequency) and 5.2 A at 300 kHz (high frequency), with frequency coefficients available for intermediate frequencies.
• Leakage Current: Specified leakage current of 642 µA (measured after 2 minutes at 20°C).
• Robust Temperature and Endurance: Operating temperature range −55°C to 105°C with an endurance (load life) of 2000 hours at 105°C.
• Surface-Mount Can Package: SMD radial can sized φ10 × 12.4 mm (L: 1.24 cm × D: 1.0 cm) with surface-mount land size L: 1.03 × W: 1.03 cm for PCB layout.
• Assembly and Handling: Embossed carrier taping and moisture-proof packing; compatible with lead-free reflow soldering conditions up to a 260°C peak as specified for the RPS series.
• Regulatory Compliance: RoHS compliant.

Typical Applications

• General-purpose electronics: Provides bulk capacitance and energy storage where a 680 µF, 6.3 V SMD solution is required for board-level power systems.
• Power filtering and decoupling in compact SMD designs: Low ESR (13 mΩ) and high ripple-current rating (up to 5.2 A at 300 kHz) support smoothing and decoupling in high-density power circuits.
• High-frequency power circuits: Designed to handle high-frequency ripple currents with frequency coefficients documented across 120 Hz–300 kHz to aid design margining.

Unique Advantages

• High capacitance in a compact can: 680 µF in a φ10 × 12.4 mm SMD package reduces board space compared with larger through-hole solutions.
• Low ESR at 100 kHz: 13 mΩ ESR enables improved voltage stability under transient and high-frequency load conditions.
• Elevated ripple capability: Support for 5.2 A ripple current at 300 kHz allows reliable operation in switching-power and high-frequency applications.
• Wide operating temperature and proven endurance: Rated from −55°C to 105°C with a 2000 hour life at 105°C for predictable long-term performance under elevated temperature stress.
• Assembly-ready packaging: Embossed carrier taping and moisture-proof packing simplify automated placement and storage, and the part meets lead-free reflow peak conditions up to 260°C as specified for the RPS series.
• Regulatory conformity: RoHS-compliant material construction supports regulatory and environmental requirements.
