RKS1H330MCNAHFGS

The RKS1H330MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor from Nichicon's RKS series. It provides 33 µF capacitance at 50 V in a compact radial can SMD package (φ8 × 6.7 mm) designed for high-frequency, high-ripple applications.

With low ESR, high allowable ripple current and an extended 3000-hour load life at 125°C, this part is suited for power management and thermal-stressed electronics where stable capacitance and long-term reliability are required.

Key Features

• Capacitance & Voltage — 33 µF rated capacitance with a 50 V rating and tolerance of −20% to +20% for predictable bulk and decoupling behavior.
• Low ESR — ESR of 30 mΩ measured at 20°C / 100 kHz, supporting efficient high-frequency operation and reduced power loss.
• High Ripple Capability — High-frequency ripple current rating of 1.6 A at 300 kHz and low-frequency ripple current of 160 mA at 120 Hz to handle switching and transient currents.
• Extended High‑Temperature Life — Rated for 3000 hours at 125°C under rated voltage, enabling use in thermally demanding environments.
• Wide Operating Temperature — Specified for −55°C to +125°C to cover a broad range of ambient conditions.
• SMD Radial Can Package — Compact φ8 × 6.7 mm package with surface-mount land size (8.3 × 8.3 mm) for space-efficient PCB integration.
• Reflow Compatible — Designed for lead-free reflow soldering with peak temperatures up to 260°C as specified in the series datasheet.
• Leakage Current — Specified leakage current ≤ 100 µA (after standard conditioning), enabling predictable standby and bias behavior.
• RoHS Compliant — Conforms to RoHS requirements for lead-free assembly environments.

Typical Applications

• Power conversion and regulation — Low ESR and high ripple capability make it suitable for DC‑DC converters and switching regulators where high-frequency decoupling is required.
• High-frequency filtering — 30 mΩ ESR at 100 kHz and 1.6 A ripple rating support EMI/RFI and output filtering in switch-mode power supplies.
• Industrial and thermal-stressed electronics — 3000-hour endurance at 125°C supports designs that operate at elevated temperatures or in harsh environments.

Unique Advantages

• Low-loss performance: 30 mΩ ESR at 100 kHz reduces conduction losses and improves converter efficiency.
• High ripple tolerance: 1.6 A high-frequency ripple rating enables reliable handling of switching currents and transients.
• Long high-temperature endurance: 3000 hours at 125°C provides predictable life and stability in hot or enclosed systems.
• Compact SMD radial can: φ8 × 6.7 mm package size and defined land pattern simplify PCB layout while saving board space.
• Reflow-ready assembly: Compatibility with lead-free reflow profiles (peak up to 260°C) supports modern surface-mount manufacturing processes.
• Controlled leakage: Leakage current specified at ≤100 µA supports reliable bias behavior after voltage application.
