RFS1A680MCN1GS

The RFS1A680MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount can package. It delivers 68 µF capacitance at a 10 V rating, engineered for general-purpose electronic applications that require low equivalent series resistance and high ripple-current capability.

Packaged in a φ5 × 5.7 mm SMD can with embossed carrier taping and moisture-proof packing, the device combines a small footprint with performance characteristics useful for decoupling, smoothing and high-frequency ripple handling in board-level designs.

Key Features

• Capacitance & Voltage: 68 µF rated capacitance with a 10 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low Loss (tan δ): tanδ (DF) = 0.12 measured at 20°C, 120 Hz, supporting stable AC performance in filtering applications.
• Very Low ESR: ESR of 30 mΩ measured at 20°C/100 kHz, enabling efficient high-frequency performance and reduced heat build-up.
• High Ripple Current Handling: Rated ripple currents include 200 mA at 120 Hz (low frequency) and 2 A at 300 kHz (high frequency), matched to the RFS series frequency coefficients.
• Leakage Current: Maximum leakage current specified at 300 µA (measured after 2 minutes at 20°C).
• Robust Endurance: Load life rated to 2000 hours at 105°C under rated voltage conditions, per RFS series endurance specification.
• Wide Operating Temperature: Specified operating range from –55°C to +105°C for use across varied thermal environments.
• Assembly Compatibility: SMD package type with lead-free reflow compatibility to a 260°C peak for standard surface-mount assembly processes.
• Packaging & Production: Supplied in embossed carrier taping with moisture-proof packing; part is in mass production and is RoHS compliant.

Typical Applications

• General Purpose Electronics – Provides compact bulk capacitance and low ESR for board-level designs requiring stable AC performance.
• Power Filtering and Decoupling – Supports ripple smoothing and decoupling tasks at frequencies up to hundreds of kilohertz thanks to low ESR and specified high-frequency ripple ratings.
• Compact Surface-Mount Designs – Delivers 68 µF in a φ5 × 5.7 mm SMD can, suitable where board space is constrained and reliable performance is required.

Unique Advantages

• Low ESR for Improved Efficiency: 30 mΩ ESR at 100 kHz reduces loss and improves thermal behavior in high-frequency circuits.
• High-Frequency Ripple Capability: Rated for up to 2 A ripple at 300 kHz, enabling reliable performance in high-speed switching environments.
• Compact, Assembly-Ready Package: φ5 × 5.7 mm SMD can with embossed carrier tape and moisture-proof packing simplifies automated placement and handling.
• Temperature and Endurance Rated: –55°C to +105°C operating range and 2000-hour life at 105°C give predictable aging behavior under elevated temperatures.
• Measured Performance Metrics: Specified tanδ, leakage current, and ripple data provide verifiable parameters for design verification and thermal management.
• RoHS Compliant and Lead-Free Reflow Compatible: Compatible with lead-free manufacturing flows and meets RoHS requirements for environmental compliance.
