RKS1C821MCNAJLGS

The RKS1C821MCNAJLGS is a surface-mount conductive-polymer aluminum electrolytic capacitor in Nichicon’s RKS series, offering 820 µF capacitance at 16 V. Designed for general-purpose power applications, it combines high capacitance density with low ESR and high allowable ripple current for compact power and decoupling designs.

Key value propositions include solid-electrolyte reliability, a wide operating temperature range from −55 °C to 125 °C, and load life endurance rated to 3000 hours at 125 °C, making it suitable for demanding thermal and ripple-current environments.

Key Features

• Conductive-polymer solid electrolyte Provides stable electrical performance and long load-life characteristics compared with traditional wet electrolytes.
• Capacitance and voltage 820 µF nominal capacitance at a 16 V rating with ±20% tolerance for bulk energy storage in compact SMD form.
• Low ESR and high ripple capability ESR of 20 mΩ (measured at 100 kHz, 20 °C) with low-frequency ripple current of 200 mA (120 Hz) and high-frequency ripple current of 2 A (300 kHz), supporting high-current decoupling and filtering.
• Frequency/loss characteristics Tangent of loss angle (tan δ) of 0.12 measured at 20 °C, 120 Hz for predictable AC loss behavior.
• Wide temperature and proven endurance Operating range −55 °C to 125 °C and a rated life of 3000 hours at 125 °C under rated voltage.
• SMD radial can package Compact φ10 × 12.4 mm can (radial, SMD) suitable for surface-mount assembly. Packaging is embossed carrier taping with moisture-proof packing for production handling.
• Manufacturing compatibility and compliance Lead-free reflow soldering compatible to 260 °C peak and RoHS compliant for modern assembly and regulatory requirements.

Typical Applications

• General-purpose power filtering Bulk decoupling and smoothing in compact SMD power supplies where high capacitance and low ESR are needed.
• DC–DC converter output stages Low ESR and high allowable ripple current support stable output filtering in converter designs.
• High-frequency decoupling Useful where combined low-frequency bulk capacitance and high-frequency ripple handling are required.

Unique Advantages

• High capacitance in compact SMD 820 µF in a φ10 × 12.4 mm can reduces board area for bulk energy storage compared with larger discrete solutions.
• Low ESR for efficient power delivery 20 mΩ ESR at 100 kHz minimizes voltage drop and power loss under AC ripple conditions.
• Robust ripple-handling Rated ripple currents of 200 mA (120 Hz) and 2 A (300 kHz) accommodate both low- and high-frequency ripple demands.
• Extended high-temperature life 3000 hours at 125 °C endurance supports long-term reliability in elevated-temperature applications.
• Assembly-ready packaging Embossed carrier taping with moisture-proof packing streamlines automated SMD assembly and storage.
• Regulatory and process compatibility RoHS compliance and lead-free reflow compatibility (260 °C peak) align with modern manufacturing and environmental requirements.
