RKS1V680MCNAJJGS

The RKS1V680MCNAJJGS is a surface-mount conductive-polymer aluminum electrolytic capacitor in Nichicon's RKS series, optimized for general-purpose power applications that require high capacitance in a compact SMD can. It combines 68 µF capacitance at a 35 V rating with low ESR and rated ripple capability to support decoupling and filtering in high-frequency and high-reliability designs.

Designed for robust operation across a wide temperature range (−55°C to 125°C) and a long load life (3000 hours at 125°C), this part addresses demands for thermal endurance, stable electrical performance and production-ready packaging.

Key Features

• Capacitance & Voltage — 68 µF nominal capacitance with a 35 V rated voltage and tolerance of −20% to +20% for reliable charge storage in power rails.
• Low ESR & High Ripple Handling — ESR of 20 mΩ (measured at 20°C/100 kHz) combined with 200 mA low-frequency ripple (120 Hz) and 2.0 A high-frequency ripple (300 kHz) to reduce voltage ripple and thermal stress in power circuits.
• Temperature & Endurance — Operating range −55°C to 125°C with a rated life of 3000 hours at 125°C for long-term stability under elevated temperatures.
• Leakage & Loss Angle — Leakage current specified at 119 µA and tanδ (loss tangent) of 0.12 (20°C, 120 Hz), enabling predictable leakage and dissipation characteristics for system power budgets.
• Surface-mount Package — Radial can SMD package sized φ10 × 10 mm for compact board-level integration and automated assembly compatibility.
• Production-ready Packaging — Supplied in embossed carrier taping with moisture-proof packing for streamlined pick-and-place and storage handling.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance in shipped product.

Typical Applications

• Power supply decoupling — Low ESR and 2.0 A high-frequency ripple capability make this part suitable for output and bulk decoupling in switching power supplies and DC-DC converters.
• High-frequency power circuits — The 20 mΩ ESR at 100 kHz and low tanδ support stability and reduced dissipation in high-frequency filtering tasks.
• Industrial and embedded electronics — Long endurance at 125°C and wide operating temperature range fit compact, thermally demanding industrial or embedded designs where sustained performance is required.

Unique Advantages

• Long high-temperature life: 3000 hours of rated endurance at 125°C supports designs that require sustained performance in elevated-temperature environments.
• High ripple tolerance with low ESR: 2.0 A high-frequency ripple rating and 20 mΩ ESR reduce voltage variation and heat build-up, improving power-train stability.
• Predictable leakage and dissipation: Specified leakage current (119 µA) and tanδ (0.12) allow accurate power-loss and standby-leakage budgeting in system design.
• SMD can in compact footprint: φ10 × 10 mm radial can SMD package delivers high capacitance in a small board area for space-constrained layouts.
• Manufacturing-friendly packaging: Embossed carrier taping and moisture-proof packing simplify automated assembly and storage handling.
• RoHS compliance: Meets environmental regulatory requirements for modern electronics production and distribution.
