RKS1J330MCNAHJGS

The RKS1J330MCNAHJGS from Nichicon is a surface-mount conductive-polymer aluminum electrolytic capacitor offering 33 µF nominal capacitance at a 63 V rating. Designed for general-purpose power applications, it combines low ESR and high allowable ripple current with an extended high-temperature endurance profile.

This SMD, polarized can-style part (embossed carrier taping / moisture-proof packing) targets power filtering and decoupling in compact modules where stable high-frequency performance, long life at elevated temperatures, and reliable SMD assembly are required.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a rated voltage of 63 V and a tolerance of −20% to +20%.
• Low ESR & High-Frequency Performance — ESR specified at 40 mΩ measured at 20°C/100 kHz for improved efficiency in high-frequency circuits.
• High Allowable Ripple Current — Supports 110 mA at 120 Hz (low frequency) and 1.1 A at 300 kHz (high frequency), enabling robust performance in switching power stages and DC–DC converters.
• Thermal Endurance — Rated operating temperature range of −55°C to +125°C with a specified load life of 3000 hours at 125°C.
• Loss Characteristics — Tangent of loss angle (tanδ) of 0.12 measured at 20°C, 120 Hz to help quantify dielectric losses in design analyses.
• Leakage Current — Specified leakage current of 103 µA for predictable standby and bias currents.
• Package & Mounting — Surface-mount radial "can" SMD package (φ8×10L) supplied in embossed carrier taping with moisture-proof packing for reflow assembly.
• Compliance — RoHS compliant.

Typical Applications

• Point-of-Load Filtering — Bulk and decoupling capacitor for DC–DC converters and POL regulators where low ESR and high ripple capability are required.
• Power Supply Smoothing — Energy storage and smoothing in switch-mode power supplies operating up to 63 V.
• High-Frequency Power Modules — Supports high-frequency ripple handling in switching and high-speed power electronics due to low ESR at 100 kHz and high allowable ripple current at 300 kHz.

Unique Advantages

• Low ESR for efficient high-frequency operation: 40 mΩ specified at 20°C/100 kHz reduces conduction losses and improves converter stability.
• High ripple-current capability: 1.1 A at 300 kHz and 110 mA at 120 Hz accommodate demanding switching environments and reduce thermal stress.
• Extended high-temperature life: 3000 hours endurance at 125°C supports long-term reliability in elevated-temperature applications.
• Compact SMD can package: φ8×10L form factor (L: 1.0 cm × D: 0.8 cm) and embossed carrier taping enable space-efficient placement and automated assembly.
• Predictable loss and leakage behavior: tanδ of 0.12 (20°C, 120 Hz) and leakage current of 103 µA aid accurate power-loss and bias current budgeting.
• RoHS compliance: Meets environmental directive requirements for lead-free applications.
