Overview of RKS1J120MCNAFGGS – Surface-Mount Conductive Polymer Aluminum Electrolytic Capacitor, 12 µF / 63 V

The RKS1J120MCNAFGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor designed for demanding thermal and ripple-current environments. It delivers a compact SMD can package with a 12 µF capacitance at 63 V and is engineered for high-frequency ripple handling and extended high-temperature endurance.

Targeted at electronics that require stable decoupling and filtering under elevated temperatures, this part combines a measured ESR, controlled loss tangent, and long load life to support reliable power delivery in compact assemblies.

Key Features

  • Capacitance and Voltage — 12 µF nominal capacitance rated at 63 V with a tolerance of −20% to +20%.
  • Conductive Polymer Electrolyte — Solid conductive polymer construction for stable performance over frequency and temperature.
  • Loss Tangent (tan δ) — Specified tan δ of 0.12 measured at 20 °C, 120 Hz for predictable dissipation characteristics.
  • ESR — Equivalent series resistance of 80 mΩ measured at 20 °C, 100 kHz, supporting lower ripple-induced voltage drop at high frequencies.
  • Ripple Current Capability — Rated low-frequency ripple current of 90 mA at 120 Hz and high-frequency ripple current of 900 mA at 300 kHz to handle dynamic power stages.
  • Leakage Current — Maximum leakage current of 100 µA after the specified conditioning.
  • High-Temperature Endurance — Load life rated to 3000 hours at 125 °C under rated voltage for long-term stability in hot operating conditions.
  • Wide Operating Temperature — Specified operating range from −55 °C to 125 °C to accommodate harsh thermal environments.
  • Surface-Mount Radial Can Package — Compact φ6.3 mm SMD can with an SMD-compatible surface-mount land size of 6.6 × 6.6 mm; supplied in embossed carrier taping with moisture-proof packing for automated assembly.
  • RoHS Compliance — Product series is stated as compliant with the RoHS directive (2011/65/EU, (EU)2015/863) per the datasheet.

Typical Applications

  • Industrial power supplies — Use for decoupling and smoothing in high-temperature power modules where long load life and high ripple handling are required.
  • DC–DC converters — Supports input/output filtering in compact converter stages with elevated switching frequencies and significant ripple currents.
  • Communications and RF modules — Suitable for high-frequency decoupling where low ESR at 100 kHz and specified high-frequency ripple current are important.

Unique Advantages

  • High-temperature endurance: 3000 hours at 125 °C ensures sustained performance in hot environments, reducing maintenance and replacement frequency.
  • High-frequency performance: 80 mΩ ESR at 100 kHz and 900 mA ripple capability at 300 kHz support effective decoupling in fast-switching power stages.
  • Predictable dissipation: Specified tan δ (0.12 at 20 °C, 120 Hz) provides consistent loss characteristics for thermal and circuit design.
  • Compact SMD can: φ6.3 mm package and standard embossed carrier taping enable automated placement in space-constrained PCBs.
  • Low leakage: 100 µA leakage current limit helps maintain charge integrity in bias and hold-up applications.
  • Supply-chain friendly packaging: Moisture-proof, embossed carrier taping supports surface-mount assembly processes and handling.
