Overview of RKS1D821MCNAJLGS – Surface-Mount Conductive Polymer Aluminum Capacitor, 820 µF, 20 V

The RKS1D821MCNAJLGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 820 µF of capacitance at a 20 V rating. It combines high capacitance density with low equivalent series resistance (ESR) and high allowable ripple current for demanding SMD power applications.

Designed for general-purpose use across a wide temperature range, this part delivers long-term stability with a rated life of 3000 hours at 125°C and packaged for automated assembly with embossed carrier taping and moisture-proof packing.

Key Features

  • Capacitance & Voltage: 820 µF nominal capacitance with a rated voltage of 20 V and tolerance of -20% to +20%.
  • Low Loss / Low ESR: ESR specified at 20 mΩ measured at 20°C / 100 kHz, supporting efficient high-frequency performance and reduced heat generation.
  • High Ripple Current Capability: Specified low-frequency ripple current of 200 mA (120 Hz) and high-frequency ripple current of 2.0 A (300 kHz), enabling robust handling of dynamic loads.
  • Leakage Current: Leakage current specified at 820 µA, providing predictable bias characteristics for system design.
  • Extended High‑Temperature Life: Rated endurance of 3000 hours at 125°C under rated voltage conditions for reliable long-term operation.
  • Wide Operating Temperature Range: –55°C to +125°C to support designs exposed to harsh thermal environments.
  • Compact SMD Can Package: Radial can SMD package with dimensions φ10 × 12.4 mm (D × L) and surface-mount mounting for space-constrained PCBs.
  • Assembly-Ready Packaging: Embossed carrier taping with moisture-proof packing for compatibility with automated placement and handling.
  • RoHS Compliance (series information): The series information indicates compliance with RoHS requirements as noted in the product documentation.

Typical Applications

  • General-Purpose SMD Designs: Intended for general-purpose surface-mount applications that require high capacitance and stable electrical performance across a wide temperature range.
  • High-Ripple Power Modules: Suited to SMD power modules and assemblies where elevated ripple currents must be handled reliably, due to its specified high-frequency and low-frequency ripple ratings.
  • High-Frequency Filtering: Low ESR at 100 kHz and explicit high-frequency ripple current capability make it appropriate for applications requiring effective high-frequency energy smoothing.

Unique Advantages

  • Low ESR for Improved Efficiency: 20 mΩ ESR at 100 kHz reduces losses and heat in high-frequency circuits.
  • High Ripple Current Handling: 2.0 A specified high-frequency ripple current supports dynamic load conditions in power stages and converters.
  • Long High‑Temperature Endurance: 3000 hours rated life at 125°C provides predictable aging and reliability for elevated-temperature environments.
  • Wide Thermal Operating Range: Operates from –55°C to +125°C to accommodate harsh or variable-temperature applications.
  • Compact, Assembly-Friendly Package: φ10 × 12.4 mm SMD can with embossed carrier taping and moisture-proof packing simplifies automated assembly and inventory handling.
  • Predictable Leakage Behavior: Specified leakage current (820 µA) aids in bias and power-budget planning.
