RKS1H330MCNAHGGS

The RKS1H330MCNAHGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor in Nichicon's RKS series. It provides 33 µF capacitance at a 50 V rating with a compact φ8 × 7.7 mm SMD can-style package and embossed carrier taping for automated assembly.

Designed for applications that require low ESR and high ripple handling across a wide temperature range (−55°C to 125°C), this part delivers long-term stability with a rated load life of 3000 hours at 125°C and RoHS compliance as specified in the series documentation.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a 50 V rated voltage and a capacitance tolerance of −20% to +20%.
• Conductive Polymer Electrolyte — Solid conductive polymer construction for stable electrical performance and reduced ESR compared with conventional wet electrolytics.
• Low ESR — Equivalent series resistance of 30 mΩ measured at 20°C/100 kHz, enabling improved high-frequency performance and better voltage stability under load.
• High Ripple Current Capability — Rated ripple current of 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) to support demanding AC and switching environments.
• Leakage and tan δ — Low leakage current specified at 100 µA and tan δ (dissipation factor) of 0.12 measured at 20°C, 120 Hz to maintain efficiency in filtering and decoupling roles.
• High Thermal Endurance — Rated for operation from −55°C to 125°C with an endurance specification of 3000 hours at 125°C and rated voltage.
• SMD Can Package & Assembly — φ8 × 7.7 mm package, surface-mount land size 8.3 × 8.3 mm, and compatibility with lead‑free reflow soldering profiles (peak 260°C per series soldering conditions).
• Packaging for Production — Supplied in embossed carrier taping with moisture-proof packing to support automated pick-and-place and storage handling.

Typical Applications

• High-frequency power circuits — Low ESR (30 mΩ at 100 kHz) and 1.6 A ripple rating at 300 kHz make this capacitor suitable for high-frequency switching and decoupling tasks.
• Power conversion stages — 50 V rating and robust ripple handling support filtering and smoothing in DC–DC converter outputs and power regulation sections.
• Industrial electronics — Wide operating temperature range (−55°C to 125°C) and 3000 h endurance at 125°C suit demanding thermal environments and longer life requirements.

Unique Advantages

• Reduced power loss — Low tan δ (0.12 at 20°C, 120 Hz) and low ESR reduce dissipation in filtering and decoupling applications, improving overall system efficiency.
• High ripple tolerance — Dual ripple specifications (160 mA at 120 Hz and 1.6 A at 300 kHz) allow the same component to address both low- and high-frequency ripple conditions.
• Thermal robustness — Rated for −55°C to 125°C and qualified for 3000 hours at 125°C, providing predictable aging and endurance in high-temperature designs.
• Assembly-friendly package — SMD can form factor with embossed carrier taping and moisture-proof packing streamlines automated assembly and board-level handling.
• Measurable, verifiable specs — Key electrical parameters (capacitance, ESR, tan δ, leakage current, ripple ratings) are specified with test conditions for straightforward engineering validation.
