RKS1J101MCNAJLGS

The RKS1J101MCNAJLGS is a surface-mount conductive polymer aluminum electrolytic capacitor offering 100 µF capacitance at a 63 V rating. It combines low equivalent series resistance and significant ripple-current capability with a compact radial can SMD package for general-purpose power applications.

Engineered for extended operation, this part is specified for 3,000 hours at 125°C and operates across a wide temperature range from −55°C to 125°C, making it suitable for designs that require stable capacitance and reliable power-conditioning performance in challenging thermal environments.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a rated voltage of 63 V and tolerance of −20% to +20%.
• Low Loss / Dissipation — tanδ (loss tangent) specified at 0.12 (20°C, 120 Hz) for predictable AC performance.
• Low ESR — ESR of 30 mΩ measured at 20°C / 100 kHz, supporting lower power loss and improved efficiency in high-frequency circuits.
• High Ripple Current Capability — Low-frequency ripple current of 140 mA (120 Hz) and high-frequency ripple current of 1.4 A (300 kHz) for robust filtering and decoupling.
• Long Endurance — Rated life of 3,000 hours at 125°C to maintain capacitance, tanδ and ESR within specified limits over extended operation.
• Wide Temperature Range — Operational range from −55°C to 125°C for reliable performance across diverse environments.
• Surface Mount, Radial Can Package — φ10 × 12.4 mm radial can SMD form factor with embossed carrier taping and moisture-proof packing for automated assembly.
• Leakage Current — Specified leakage current of 315 µA to support predictable standby and idle-state behavior.
• RoHS Compliant — Meets RoHS requirements as specified in the product data.

Typical Applications

• Power supply decoupling — Low ESR and high ripple-current handling make this capacitor suitable for smoothing and stabilizing DC rails in power supplies.
• Input filtering for power modules — The 63 V rating and high-frequency ripple capability support input-side filtering for converters and regulators.
• Bulk energy storage in compact assemblies — 100 µF capacitance in a small φ10 × 12.4 mm SMD can provides bulk capacitance where board space is constrained.

Unique Advantages

• Stable high-temperature endurance: 3,000-hour life at 125°C ensures longer service intervals and predictable ageing for thermal-stressed designs.
• Efficient high-frequency performance: 30 mΩ ESR at 100 kHz and 1.4 A high-frequency ripple rating reduce temperature rise and power loss in switching environments.
• Compact SMD radial-can footprint: φ10 × 12.4 mm size with embossed carrier taping simplifies placement in automated SMT lines while delivering high capacitance density.
• Controlled leakage and dissipation: Specified leakage current and tanδ provide designers with measurable parameters for power budgeting and stability analysis.
• Series-level quality characteristics: Conductive polymer aluminum construction and series specifications support consistent electrical performance across production lots.
