RKS1E101MCNAHGGS

The RKS1E101MCNAHGGS from Nichicon is a surface-mount conductive-polymer aluminum electrolytic capacitor offering 100 µF nominal capacitance at a 25 V rating. It combines low equivalent series resistance (ESR) and high allowable ripple currents with a wide operating temperature range to support demanding power and high-frequency decoupling needs.

Engineered for robust thermal endurance, the part is specified for operation from −55 °C to 125 °C with a rated load life of 3000 hours at 125 °C, making it suitable for designs that require sustained performance under elevated temperature and high ripple conditions.

Key Features

• Capacitance & Voltage: 100 µF nominal capacitance with a 25 V rated voltage and tolerance of −20% to +20% for predictable bulk and decoupling behavior.
• Low Loss / Low DF: tanδ (DF) of 0.12 measured at 20 °C, 120 Hz, minimizing dissipation in AC or ripple environments.
• Low ESR: 30 mΩ ESR specified at 20 °C, 100 kHz, enabling efficient high-frequency performance and reduced heating.
• High Ripple Current Capability: 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) for handling switching and high-frequency ripple on power rails.
• Leakage Current: Specified leakage current of 125 µA after standard conditioning for predictable bias behavior.
• High Temperature Endurance: Load life rated 3000 hours at 125 °C, supporting long-term operation in elevated-temperature environments.
• Surface-Mount Can Package: Radial can SMD package, size φ8 × 7.7 mm (diameter × length), supplied in embossed carrier taping with moisture-proof packing for pick-and-place compatibility.
• Assembly Compatibility: Designed for lead-free reflow soldering with peak temperature compatibility up to 260 °C as specified for reflow conditions.
• Regulatory: RoHS compliant.

Typical Applications

• High-frequency power rails: Low ESR (30 mΩ @100 kHz) and 1.6 A ripple capability at 300 kHz make this capacitor well suited for smoothing and decoupling on switching regulators and high-frequency converters.
• Bulk energy storage near loads: 100 µF capacitance and low loss characteristics provide bulk capacitance for local energy buffering in compact SMD layouts.
• High-temperature electronics: Rated for −55 °C to 125 °C with 3000-hour life at 125 °C, supporting designs that must maintain capacitance and ESR under sustained elevated temperatures.

Unique Advantages

• High ripple handling: Specified ripple current values at both low and high frequencies allow designers to manage switching noise and large current swings without excessive heating.
• Thermal robustness: 3000-hour life at 125 °C provides predictable long-term performance in high-temperature environments, reducing the need for frequent derating or overspecification.
• Low ESR for compact designs: 30 mΩ ESR at 100 kHz helps reduce voltage drop and power loss, enabling smaller capacitance networks or fewer parallel components.
• Reflow-compatible SMD can: Embossed carrier taping and moisture-proof packing combined with 260 °C reflow compatibility streamline automated assembly processes.
• Predictable leakage and loss: Specified leakage current (125 µA) and tanδ (0.12 @120 Hz) support accurate modeling of standby and AC-loss behavior in power-sensitive designs.
