RKS1J330MCNAJJGS

The RKS1J330MCNAJJGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor in the RKS series, offering 33 µF capacitance with a 63 V rating. It is designed for general-purpose electronic use where low equivalent series resistance, elevated ripple handling and extended high-temperature endurance are required.

Key attributes include low ESR (30 mΩ at 100 kHz), high-frequency ripple capability (1.4 A at 300 kHz), a wide operating temperature range (–55 °C to 125 °C) and a 3000 hour load life at 125 °C, all supplied in a compact φ10 × 10 mm SMD radial-can package with embossed carrier taping.

Key Features

• Capacitance & Tolerance — 33 µF nominal capacitance with a tolerance of −20% to +20% (±20% at 120 Hz, 20 °C).
• Voltage Rating — Rated for 63 V DC operation.
• Low ESR — Equivalent series resistance of 30 mΩ measured at 100 kHz and 20 °C for improved power delivery and stability at high frequencies.
• High Ripple Current — Low-frequency allowable ripple current of 140 mA at 120 Hz and high-frequency ripple current of 1.4 A at 300 kHz to support demanding AC and switching environments.
• Thermal Endurance — Wide operating range from −55 °C to 125 °C and load life specification of 3000 hours at 125 °C ensuring long-term thermal reliability.
• Electrical Loss & Leakage — Dissipation factor (tan δ) of 0.12 at 20 °C, 120 Hz and specified leakage current of 103 µA.
• Package & Mounting — Surface-mount radial-can SMD (φ10 × 10 mm), supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Reflow & Compliance — Designed for lead-free reflow soldering up to a 260 °C peak (per series soldering specifications) and declared compliant with the RoHS directives noted in the series datasheet.

Typical Applications

• General purpose electronics — Use where a 63 V, 33 µF SMD capacitor with low ESR and wide temperature capability is required for reliable operation.
• Power supply filtering — Appropriate for designs that need bulk capacitance and high ripple handling at both low and high frequencies, supported by the specified ripple current ratings.
• High-temperature environments — Suited to applications that demand continuous operation at elevated temperatures thanks to the −55 °C to 125 °C range and 3000 h endurance at 125 °C.

Unique Advantages

• Low ESR for improved power performance: 30 mΩ at 100 kHz reduces losses and supports stable operation in switching and high-frequency circuits.
• High ripple capability: 1.4 A at high frequency and 140 mA at low frequency accommodate both switching supplies and AC ripple conditions.
• Extended high-temperature life: 3000 hours at 125 °C provides predictable longevity in thermally demanding designs.
• SMD radial-can packaging: φ10 × 10 mm SMD format with embossed carrier taping simplifies automated placement and handling.
• Measurable electrical characteristics: Specified tan δ, leakage current, and ESR values enable engineering verification and predictable performance.
• RoHS-declared series compliance: Series-level declaration supports regulatory requirements as shown in the datasheet content.
