RKS1D101MCNAFGGS

The RKS1D101MCNAFGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor (RKS series, Nichicon) offering 100 µF nominal capacitance at a 20 V rating. Its compact radial can SMD package (φ6.3 × 7.7 mm) and low ESR characteristics make it suited for compact power assemblies and high-frequency power circuits that require robust decoupling and filtering.

Designed for elevated operating temperatures (−55 °C to 125 °C) and long load life (3000 hours at 125 °C), this part targets applications that demand stable capacitance, low loss, and high ripple-current handling in a space-efficient SMD form factor. The device is RoHS compliant.

Key Features

• Dielectric / Architecture Conductive polymer aluminum solid electrolyte construction for stable capacitance and low-loss behaviour.
• Capacitance & Voltage 100 µF nominal capacitance with a rated voltage of 20 V and tolerance of −20% to +20%.
• Low Loss & Dissipation Tangent of loss angle (tan δ) of 0.12 measured at 20 °C, 120 Hz, supporting efficient energy handling at AC conditions.
• Low ESR ESR of 30 mΩ measured at 20 °C and 100 kHz, enabling effective high-frequency filtering and reduced power dissipation.
• High Ripple-Current Capability Low-frequency ripple current 140 mA (120 Hz) and high-frequency ripple current 1.4 A (300 kHz) for demanding switching environments.
• Leakage Current Specified leakage current up to 100 µA, supporting predictable DC behavior after voltage application.
• Thermal Endurance Rated to operate from −55 °C to 125 °C with a load-life specification of 3000 hours at 125 °C.
• Package & Mounting Surface-mount radial can (φ6.3 × 7.7 mm), supplied in embossed carrier taping with moisture-proof packing for automated assembly.

Typical Applications

• Switching Power Supplies Output filtering and decoupling in DC–DC converters benefiting from low ESR and high ripple-current capability at switching frequencies.
• High-Frequency Power Modules Local energy storage and smoothing for high-frequency regulators where compact SMD capacitors with stable HF performance are required.
• Embedded Power Electronics Decoupling and bulk capacitance in compact embedded systems operating in elevated-temperature environments up to 125 °C.

Unique Advantages

• High thermal endurance: 3000 hours load life at 125 °C provides predictable long-term performance in elevated-temperature assemblies.
• Low ESR for efficient filtering: 30 mΩ (100 kHz) reduces power loss and improves regulation in switching applications.
• High ripple-current handling: Rated for 1.4 A at 300 kHz and 140 mA at 120 Hz to support both high-frequency and low-frequency ripple environments.
• Compact SMD form factor: φ6.3 × 7.7 mm package enables space-efficient placement on densely populated PCBs.
• Stable dielectric performance: tan δ = 0.12 (20 °C, 120 Hz) and controlled leakage current (100 µA) for reliable AC and DC performance.
• Supply-ready packaging: Embossed carrier taping with moisture-proof packing supports automated surface-mount assembly.
