RKS1J330MCNAHGGS

The RKS1J330MCNAHGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor rated at 33 µF and 63 V. It combines low ESR and high allowable ripple current with extended high-temperature endurance for demanding board-level power decoupling and filtering.

Designed for SMD assembly, this part supports lead‑free reflow processes and offers a long load life of 3000 hours at 125°C, making it suitable where sustained performance under elevated temperature and ripple stress is required.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance at 20°C, 120 Hz.
• Conductive Polymer Electrolyte — Solid conductive polymer construction for improved ripple handling and stability compared with liquid electrolytes.
• Low ESR — ESR of 40 mΩ measured at 20°C and 100 kHz, enabling efficient high‑frequency performance and reduced losses.
• High Ripple Current — Low-frequency ripple current of 110 mA at 120 Hz and high-frequency ripple current of 1.1 A at 300 kHz for demanding switching applications.
• High-Temperature Endurance — Rated life of 3000 hours at 125°C, with specified limits for capacitance change, tan δ and ESR after endurance testing.
• Wide Operating Temperature Range — Specified to operate from −55°C to +125°C.
• Reflow Compatibility — SMD package designed for lead‑free reflow soldering; withstands peak temperatures up to 260°C per soldering heat specifications.
• Compact SMD Can — Radial, can-style SMD package with dimensions φ8 × 7.7 mm and recommended land size 8.3 × 8.3 mm for board-level integration.

Typical Applications

• High‑ripple power stages — Use where high allowable ripple current and low ESR are required for input/output filtering in switching converters.
• High‑temperature electronics — Suitable for board-level circuits that require reliable capacitance and performance up to 125°C for extended periods.
• SMD production lines — Designed for lead‑free reflow processes, enabling integration into modern surface-mount assembly workflows.

Unique Advantages

• Long high‑temperature life: 3000 hours at 125°C provides predictable aging and durability in elevated-temperature environments.
• High-frequency readiness: 40 mΩ ESR at 100 kHz and 1.1 A ripple at 300 kHz reduce losses and improve stability in fast-switching power circuits.
• Solid polymer reliability: Conductive polymer electrolyte minimizes leakage and enhances tolerance to ripple and thermal stress.
• Reflow-friendly SMD can: Packaging and soldering profile support lead‑free reflow to 260°C for modern assembly processes.
• Compact footprint: φ8 × 7.7 mm SMD can provides a space-efficient solution for board-level decoupling and filtering tasks.
