RKS1C102MCNAJJGS

The RKS1C102MCNAJJGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 1000 µF capacitance at 16 V. Engineered for general-purpose power applications, it combines high capacitance density with low equivalent series resistance to support high-frequency ripple and bulk energy storage in compact SMD form factors.

With a wide operating range from –55 °C to 125 °C and a rated load life of 3000 hours at 125 °C, this part addresses demanding thermal and reliability requirements while supporting lead-free reflow assembly and moisture-proof taped packaging for automated production.

Key Features

• Capacitance & Voltage — 1000 µF rated capacitance at 16 V with tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Low ESR and Loss — ESR of 20 mΩ (measured at 20 °C, 100 kHz) and tanδ = 0.12 (20 °C, 120 Hz) for efficient high-frequency performance.
• High Ripple Current Capability — Low-frequency ripple current 210 mA (120 Hz) and high-frequency ripple current 2.1 A (300 kHz), enabling handling of switching noise and converter ripple currents.
• Leakage Current — Specified leakage current of 800 µA after voltage application.
• Wide Temperature & Long Life — Operating range −55 °C to 125 °C with endurance rated at 3000 hours at 125 °C for sustained high-temperature operation.
• SMD Package & Assembly — φ10 × 10 mm can (SMD radial can) supplied in embossed carrier taping with moisture-proof packing for automatic placement; compatible with lead-free reflow up to 260 °C peak.
• Environmental Compliance — Series-level compliance with RoHS directives as documented in the product datasheet.

Typical Applications

• Power supply decoupling — Bulk and output-side decoupling in DC–DC converters where 1000 µF and low ESR reduce voltage ripple and improve regulator stability.
• Switching power modules — Energy smoothing for high-frequency switching stages leveraging 2.1 A HF ripple capability and low-loss characteristics.
• Embedded and industrial electronics — Bulk energy storage and hold-up in compact SMD designs that require wide temperature operation and extended lifetime at elevated temperatures.

Unique Advantages

• High ripple tolerance: The combination of low ESR (20 mΩ) and 2.1 A HF ripple rating supports tighter voltage regulation in switching circuits.
• High-temperature endurance: Rated for 3000 hours at 125 °C, providing predictable performance in thermally demanding environments.
• Compact SMD can: φ10 × 10 mm package delivers high capacitance density in a small footprint for space-constrained designs and automated assembly.
• Reflow-compatible assembly: Designed for lead-free reflow (260 °C peak) and supplied in embossed carrier taping with moisture-proof packing, simplifying production flow.
• Measurable, verifiable specs: Key electrical parameters (capacitance, ESR, tanδ, leakage, ripple) are specified with measurement conditions for straightforward selection and validation.
