The RHS1C681MCN1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount φ8×11.7 mm can. It delivers 680 µF at 16 V with a polymer electrolyte architecture designed for low ESR and high ripple-current performance.

Engineered for general-purpose electronics, this Nichicon RHS series part offers high-frequency performance, a wide operating temperature range of −55°C to 105°C, and a rated endurance of 2000 hours at 105°C for reliable operation in demanding assemblies.

Key Features

• Capacitance and Voltage — 680 µF nominal capacitance at a rated voltage of 16 V with tolerance −20% to +20% for predictable bulk energy storage.
• Conductive Polymer Construction — Solid polymer electrolyte formulation combined with aluminum anode to achieve low ESR and improved high-frequency behavior.
• Low ESR — ESR of 14 mΩ measured at 20°C / 100 kHz, supporting reduced losses and improved voltage stability under dynamic load.
• High Ripple-Current Capability — Rated ripple currents of 495 mA at 120 Hz and 4.95 A at 300 kHz, suitable for handling both low- and high-frequency ripple components.
• Thermal and Endurance Ratings — Operating temperature range from −55°C to 105°C with a load life/endurance rating of 2000 hours at 105°C.
• Compact SMD Can Package — φ8 × 11.7 mm radial can in an SMD-compatible form factor with embossed carrier taping and moisture-proof packing for assembly.
• Leakage and Dissipation — Leakage current specified at 2176 µA and tan δ of 0.12 (measured at 20°C, 120 Hz), enabling design trade-offs to be set precisely.
• RoHS Compliant — Conforms to RoHS requirements for restricted substances.

Typical Applications

• General-purpose electronics — Bulk energy storage and decoupling in a wide range of consumer and industrial circuits where reliable smoothing and low ESR are required.
• Power modules and supply rails — Handling ripple and transient currents on local power rails in compact surface-mount designs.
• High-frequency filtering — Providing low-ESR performance for high-frequency noise attenuation in power delivery networks.

Unique Advantages

• Measurable low-loss performance: 14 mΩ ESR at 100 kHz delivers lower loss under switching and high-frequency conditions, aiding thermal and efficiency goals.
• High-frequency ripple capability: 4.95 A ripple current rating at 300 kHz supports modern high-speed power conversion and filtering needs.
• Wide operating range: −55°C to 105°C operation and 2000-hour endurance at 105°C provide predictable lifetime behavior in elevated-temperature environments.
• SMD can in a compact footprint: φ8×11.7 mm package offers a space-efficient solution for surface-mount assemblies while retaining high capacitance.
• Manufacturing-ready packaging: Supplied in embossed carrier tape with moisture-proof packing to support automated assembly and storage.
• Regulatory alignment: RoHS compliance supports inclusion in designs targeting restricted-substance requirements.
