RKS1J120MCNAHGGS

The RKS1J120MCNAHGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor providing 12 µF capacitance at a 63 V rated voltage. Designed for high-frequency, high-ripple applications, it combines low ESR and measured high-frequency ripple capability with a compact radial SMD can package.

With an operating temperature range from −55 °C to 125 °C and a rated load life of 3000 hours at 125 °C, this part targets power electronics and high-temperature embedded systems that require stable capacitance, low loss, and durable performance under elevated temperatures and ripple stress.

Key Features

• Conductive polymer aluminum construction — Solid electrolytic design for improved high-frequency performance and stable ESR characteristics.
• Capacitance and tolerance — 12 µF with tolerance −20% to +20% measured at 20 °C, 120 Hz.
• Rated voltage — 63 V DC for mid-voltage power applications.
• Low ESR — 40 mΩ specified at 20 °C, 100 kHz, supporting low-loss operation in high-frequency circuits.
• High ripple capability — 110 mA at 120 Hz and 1.1 A at 300 kHz (high-frequency ripple current) for demanding switching environments.
• Leakage current — Specified at 100 µA (or per datasheet leakage condition), supporting predictable bias behavior.
• High-temperature endurance — Rated life of 3000 hours at 125 °C, enabling use in elevated temperature duty cycles.
• Surface-mount, radial can package — φ8 × 7.7 mm size (L: 7.7 × D: 8 mm) with embossed carrier taping and moisture-proof packing for automated assembly.
• Reflow compatible — Compatible with lead-free reflow soldering peak temperatures up to 260 °C as specified for SMD processing.
• RoHS compliant — Conforms to RoHS directive per product data.

Typical Applications

• High-frequency power modules — Low ESR and specified ripple current at 300 kHz make this capacitor suitable for decoupling and smoothing in high-frequency converters and switching regulators.
• Industrial electronics — Long life at elevated temperature (3000 h at 125 °C) supports power subsystems used in thermally demanding environments.
• Communications and computing power rails — Stable capacitance and low loss at 100 kHz help maintain voltage stability on intermediate and output rails.

Unique Advantages

• High ripple current handling: Rated ripple currents (110 mA at 120 Hz; 1.1 A at 300 kHz) reduce the need for parallel capacitors in many high-frequency designs.
• Low ESR at high frequency: 40 mΩ at 100 kHz lowers power loss and thermal rise in switching applications.
• Robust high-temperature endurance: 3000 hours at 125 °C provides predictable life performance in hot operating conditions.
• SMD-ready packaging and reflow compatibility: Radial can SMD package with embossed carrier taping and moisture-proof packing supports automated assembly and lead‑free reflow processes.
• Compact footprint: φ8 × 7.7 mm size offers a high-capacitance option for space-constrained power electronics layouts.
• Predictable leakage behavior: Specified leakage limits enable reliable bias and startup characteristics in power systems.
