RKS1D330MCNAHJGS

The RKS1D330MCNAHJGS is a surface‑mount conductive‑polymer aluminum solid electrolytic capacitor from Nichicon’s RKS series. It delivers 33 µF capacitance at a 20 V rating with low equivalent series resistance and high allowable ripple current, optimized for general‑purpose power filtering and decoupling in compact SMD assemblies.

Designed for reliability in demanding thermal environments, this part offers a wide operating range from −55°C to 125°C and a rated life of 3000 hours at 125°C, making it suitable for applications that require sustained high‑temperature endurance and stable electrical performance.

Key Features

• Capacitance & Tolerance — 33 µF nominal with tolerance −20% to +20% (measured at 120 Hz, 20°C).
• Voltage Rating — 20 V rated voltage for general‑purpose power applications.
• Low ESR — 25 mΩ ESR measured at 20°C / 100 kHz, supporting low‑loss operation at high frequencies.
• High Ripple Current Capability — 170 mA at 120 Hz (low frequency) and 1.7 A at 300 kHz (high frequency) to handle demanding ripple conditions.
• Leakage Current — Maximum 100 µA after conditioning, supporting predictable bias behavior.
• Robust Endurance — Rated life of 3000 hours at 125°C; endurance criteria include capacitance change within ±20% and ESR/tan δ within specified limits.
• Wide Temperature Range — Operates from −55°C to 125°C for thermal resilience in harsh environments.
• Surface‑Mount Can Package — Compact φ8 × 10 mm (L × D) radial, can‑style SMD package for space‑efficient board layouts.
• Assembly‑Ready Packaging — Supplied in embossed carrier taping with moisture‑proof packing for automated placement.
• Reflow Compatible — Designed to meet lead‑free reflow soldering conditions up to 260°C peak (soldering profile guidelines provided in the datasheet).
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power Supplies and Power Management — Smoothing and decoupling on power rails where low ESR and high ripple handling are required.
• Embedded and Compact Electronics — Board‑level energy storage and filtering in space‑constrained surface‑mount designs.
• Industrial Controls and Instrumentation — Power filtering and stability in systems operating across wide temperature ranges.
• Communications Equipment — High‑frequency bypass and decoupling where low loss at 100 kHz+ is beneficial.

Unique Advantages

• Low loss at high frequency: 25 mΩ ESR at 100 kHz minimizes conduction losses and improves efficiency in high‑frequency circuits.
• High ripple tolerance: Rated for 1.7 A at 300 kHz, enabling reliable performance under significant AC stress on power rails.
• Long high‑temperature life: 3000 hours at 125°C provides predictable aging and endurance in elevated‑temperature environments.
• Compact SMD can: φ8 × 10 mm package balances capacitance density with a small board footprint for automated assembly.
• Assembly and process friendly: Embossed carrier taping and moisture‑proof packing support high‑volume placement, and compatibility with 260°C peak reflow simplifies integration into lead‑free processes.
• Predictable leakage behavior: Specified leakage current limit (100 µA) and conditioning guidance help control bias current in sensitive circuits.
