RKS1J100MCNAHFGS

The RKS1J100MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 10 µF capacitance at a 63 V rated voltage. It combines low equivalent series resistance and high allowable ripple current in a compact φ8 × 6.7 mm can-style SMD package optimized for high-frequency power applications.

Designed for demanding thermal and lifetime environments, this capacitor supports operation from −55°C to 125°C with a rated load life of 3000 hours at 125°C and is supplied in embossed carrier taping with moisture-proof packing for automated assembly.

Key Features

• Capacitance & Voltage — 10 µF nominal capacitance with a 63 V rated voltage and tolerance of −20% to +20% at 20°C, 120 Hz.
• Low ESR — ESR of 40 mΩ measured at 20°C, 100 kHz for improved power integrity and reduced dissipation in high-frequency circuits.
• High Ripple Current Capacity — Low-frequency ripple current 110 mA (120 Hz) and high-frequency ripple current 1.1 A (300 kHz) to support switching power stages and high-frequency decoupling.
• Wide Temperature & Long Life — Operating range −55°C to +125°C with a load life/endurance of 3000 hours at 125°C under rated voltage.
• Surface-Mount Package — Radial can SMD package (φ8 × 6.7 mm) with recommended land pattern L: 8.3 × W: 8.3 mm; supplied in embossed carrier taping and moisture-proof packing for pick-and-place assembly.
• Low Loss Tangent — tan δ of 0.12 (measured at 20°C, 120 Hz) for stable performance in AC-biased and ripple-prone applications.
• Leakage Current Performance — Leakage current specified at 100 µA (after 2 minutes at rated voltage) to support low-leakage designs.
• RoHS Compliant — Product conforms to the RoHS directive as noted in the series datasheet.

Typical Applications

• Power supply decoupling — Low ESR and 1.1 A ripple capability at high frequency make this capacitor suitable for output filtering and decoupling in switching supplies.
• Switching regulator output filtering — Stable capacitance over −55°C to 125°C and high ripple handling support use on regulator outputs in thermally challenging environments.
• High-frequency power modules — Compact SMD can package with low loss tangent and high-frequency ripple current ratings supports board-level integration in high-density power assemblies.

Unique Advantages

• High ripple tolerance: Rated for 1.1 A at 300 kHz and 110 mA at 120 Hz, enabling use in demanding switching and ripple-heavy circuits.
• Low dissipation in compact form: 40 mΩ ESR at 100 kHz reduces heat generation while fitting a φ8 × 6.7 mm SMD footprint for space-constrained designs.
• Long high-temperature lifetime: 3000 hours at 125°C provides predictable endurance and reliability for long-term deployments in hot operating environments.
• SMD assembly-ready: Supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow profiles specified in the series datasheet.
• Stable electrical characteristics: tan δ 0.12 and a controlled leakage current (100 µA) support consistent performance across frequency and temperature ranges.
