RKS1D101MCNAJJGS

The RKS1D101MCNAJJGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor providing 100 µF capacitance at a 20 V rating. It combines low ESR, high allowable ripple current, and a wide operating temperature range for demanding board-level power applications.

Designed for general-purpose use, this SMD radial-can capacitor delivers long-term reliability with a specified load life of 3000 hours at 125°C and RoHS compliance for modern assembly processes.

Key Features

• Dielectric / Construction — Conductive polymer aluminum solid electrolytic construction for stable performance and low loss (tanδ = 0.12 at 20°C, 120 Hz).
• Capacitance & Tolerance — 100 µF with tolerance of −20% to +20% at 20°C, 120 Hz, suitable for consistent bulk capacitance requirements.
• Voltage Rating — Rated at 20 V for a range of low-voltage power applications.
• Low ESR — ESR of 20 mΩ measured at 20°C / 100 kHz, supporting improved transient response and reduced dissipation.
• High Ripple Current Capability — Low-frequency ripple current 200 mA (120 Hz) and high-frequency ripple current 2.0 A (300 kHz) to handle switching and high-frequency loading.
• Leakage & Reliability — Leakage current specified at 100 µA and an endurance rating of 3000 hours at 125°C to support prolonged field operation.
• Wide Temperature Range — Operating from −55°C to +125°C for use across broad thermal environments.
• Package & Assembly — SMD radial can (φ10 × 10 mm) supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow soldering conditions up to a 260°C peak per the product specification.
• Regulatory — RoHS compliant.

Typical Applications

• General Purpose Power Filtering — Bulk decoupling and smoothing where 100 µF at 20 V with low ESR is required to stabilize supply rails.
• Switching Power Supplies — Handles high-frequency ripple currents (2.0 A @ 300 kHz) to support converters and regulators.
• Industrial Electronics — Suitable for board-level power subsystems operating across −55°C to +125°C and requiring long life (3000 h at 125°C).

Unique Advantages

• Low ESR for Improved Transient Response: 20 mΩ ESR at 100 kHz reduces voltage droop and switching losses in high-frequency circuits.
• High Ripple Handling: 2.0 A high-frequency ripple rating enables reliable performance in switching and pulse-loaded environments.
• High-Temperature Endurance: Rated 3000 hours at 125°C to support long-term reliability in elevated-temperature applications.
• Compact SMD Radial Package: φ10 × 10 mm SMD can simplifies board placement while delivering high capacitance density.
• Assembly-Ready: Supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow profiles up to 260°C peak.
• Regulatory Compliance: RoHS compliant to meet modern environmental and manufacturing requirements.
