RKS1C681MCNAJLGS

The RKS1C681MCNAJLGS from Nichicon is a surface-mount conductive polymer aluminum electrolytic capacitor delivering 680 µF nominal capacitance at a 16 V rating. It combines high capacitance in a compact radial can SMD package with low loss (tanδ) and low ESR to support power filtering and decoupling in compact electronics.

Designed for general-purpose use, this part targets applications that require high ripple handling and stable performance across a wide temperature range, backed by a 3000-hour rated life at 125°C and moisture-proof embossed carrier taping for automated assembly.

Key Features

• Capacitance & Tolerance — 680 µF nominal with -20% to +20% tolerance (measured at 20°C, 120 Hz).
• Rated Voltage — 16 V DC rated for typical low-voltage power rails and decoupling duties.
• Low Loss & Stable Performance — tanδ (loss tangent) of 0.12 at 20°C/120 Hz for low dissipation in filtering applications.
• Low ESR & High Ripple Capability — ESR of 20 mΩ at 20°C/100 kHz and high-frequency ripple current rating of 2.0 A (at 300 kHz), plus 200 mA at 120 Hz for low- and high-frequency ripple management.
• Long Life & Wide Temperature Range — Rated for 3000 hours at 125°C and operating range from -55°C to 125°C for demanding thermal environments.
• Surface-Mount Radial Can Package — Compact φ10 × 12.4 mm (D × L) package optimized for SMD assembly; supplied in embossed carrier taping with moisture-proof packing for production use.
• Leakage Current — Specified leakage current of 544 µA (measured per product data conditions).
• RoHS Compliance (series) — Series documentation indicates compliance with RoHS directives for lead-free assemblies and reflow processing to a 260°C peak.

Typical Applications

• Power Supply Filtering — Bulk and output filtering on low-voltage DC rails where 680 µF and low ESR improve ripple suppression and transient response.
• DC‑DC Converter Output — Smoothing and decoupling on converter outputs that require compact, high-capacitance SMD solutions with high ripple capability.
• Embedded and Industrial Electronics — General-purpose energy storage and smoothing in compact boards operating across -55°C to 125°C.

Unique Advantages

• High Capacitance in a Compact SMD Can: 680 µF in a φ10 × 12.4 mm package reduces board area while providing substantial energy storage.
• Low ESR at High Frequency: 20 mΩ at 100 kHz and a 2.0 A high-frequency ripple rating enable effective decoupling for fast switching supplies.
• Extended High‑Temperature Life: 3000 hours at 125°C supports long-term reliability in thermally demanding designs.
• Assembly-Ready Packaging: Embossed carrier taping with moisture-proof packing simplifies automated placement and board assembly workflows.
• Stable Loss Characteristics: tanδ of 0.12 at 20°C/120 Hz delivers predictable dissipation for thermal budgeting and performance planning.
