The RKS1V100MCNAFEGS from Nichicon is a surface-mount conductive polymer aluminum electrolytic capacitor offering 10 µF capacitance at a 35 V rating. Engineered for high-temperature endurance and elevated ripple handling, this SMD device targets designs that require low ESR at high frequencies and long operational life in compact packages.

With a rated temperature range of −55 °C to +125 °C and a specified load life of 3000 hours at 125 °C, the RKS series component delivers consistent capacitance, controlled dissipation factor, and predictable leakage for demanding power and high-frequency applications.

Key Features

• Capacitance & Voltage: 10 µF nominal capacitance with a rated voltage of 35 V and ±20% tolerance at 120 Hz, 20 °C.
• Low ESR for High-Frequency Performance: ESR of 60 mΩ measured at 100 kHz, 20 °C supports lower losses in high-frequency circuits.
• High Frequency & Low Frequency Ripple Handling: High-frequency ripple current rated at 900 mA (300 kHz) and low-frequency ripple current rated at 90 mA (120 Hz), enabling effective filtering across frequency ranges.
• Thermal Endurance: Rated operating temperature −55 °C to +125 °C with a load life of 3000 hours at 125 °C, providing long-term stability under elevated temperature stress.
• Reliable Leakage and Dissipation Characteristics: Leakage current specified at 100 µA and tan δ (DF) 0.12 measured at 20 °C, 120 Hz for predictable dielectric behavior.
• Compact SMD Package: Radial can SMD footprint with dimensions Ø6.3 × 5.8 mm (L × D) and recommended surface-mount land size 6.6 × 6.6 mm, supplied in embossed carrier taping with moisture-proof packing for production pick-and-place.
• RoHS Compliant: Conforms to RoHS requirements as indicated in product documentation.

Typical Applications

• Power supply decoupling and output filtering: Low ESR (60 mΩ at 100 kHz) and 900 mA high-frequency ripple capability make this capacitor suitable for smoothing and energy storage on DC‑DC converter outputs and regulator rails.
• High-frequency power stages: The combination of low dissipation factor and measured HF ripple current supports use in switching power stages and other high-frequency circuits.
• Industrial and telecom electronics: Extended temperature range (−55 °C to +125 °C) and 3000-hour life at 125 °C address reliability needs in industrial power modules and telecom power supplies.

Unique Advantages

• Consistent high-temperature endurance: 3000-hour rated life at 125 °C provides predictable ageing behavior for designs exposed to sustained elevated temperatures.
• Broad frequency ripple capability: Separate ripple ratings for low (120 Hz) and high (300 kHz) frequencies give designers quantifiable margins for both mains-related and switching noise.
• Compact footprint with SMD convenience: Ø6.3 × 5.8 mm can-style SMD package simplifies board layout while enabling automated assembly and moisture-safe handling.
• Measured high-frequency performance: ESR specified at 100 kHz (60 mΩ) and tan δ data allow engineers to model loss and thermal rise with confidence.
• Predictable leakage behavior: Leakage current spec of 100 µA supports designs that require controlled standby current and predictable voltage hold characteristics after power application.
