RKS1D331MCNAHHGS

The RKS1D331MCNAHHGS is a surface-mount conductive polymer aluminum electrolytic capacitor offering 330 µF capacitance at a 20 V rating. It is designed for SMD power applications that require high ripple-current handling, low equivalent series resistance (ESR), and extended operation in elevated-temperature environments.

Built for reliability under thermal stress, the device delivers a long rated life at high temperature and is compatible with lead‑free reflow processes, making it suitable for compact, high-density power designs and other demanding electronic assemblies.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 20 V and a capacitance tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Low ESR — ESR of 30 mΩ measured at 20°C, 100 kHz, helping to reduce power loss and temperature rise in high-frequency circuits.
• High Ripple Current Capability — Low-frequency ripple current of 160 mA (120 Hz) and high-frequency ripple current of 1.6 A (300 kHz), specified for robust performance in switching and high-frequency power environments.
• Leakage & Loss Characteristics — Leakage current specified at 330 µA and tangent of loss angle (tan δ) of 0.12 (measured at 20°C, 120 Hz), providing predictable behavior for energy storage and decoupling tasks.
• High-Temperature Endurance — Rated operating temperature range of −55°C to +125°C with a load life of 3000 hours at 125°C (endurance test condition), enabling sustained performance in elevated-temperature applications.
• SMD Package & Dimensions — Compact radial can SMD package, size Ø8 × 8.7 mm (L × D), and recommended land pattern 8.3 × 8.3 mm; supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Reflow Compatibility & RoHS — Designed for lead‑free reflow soldering with a peak temperature correspondence to 260°C and compliant with RoHS requirements.

Typical Applications

• Power conversion — Bulk storage and smoothing in DC‑DC converters where high capacitance and high-frequency ripple handling are required.
• Switching power supplies — Input/output decoupling and energy buffering in switching regulators that benefit from low ESR and high ripple current capability.
• High-frequency power modules — Local decoupling in power modules and point-of-load circuits where reduced losses at 100 kHz+ improve thermal margin.
• High-temperature electronics — Applications operating up to 125°C that require long life under elevated-temperature conditions (3000 h at 125°C rated life).

Unique Advantages

• High capacitance in a compact SMD can: 330 µF in a φ8 × 8.7 mm package provides substantial bulk capacitance while conserving board area.
• Reduced power loss: Low ESR (30 mΩ @100 kHz) minimizes dissipation in high-frequency circuits, supporting cooler operation and improved efficiency.
• High ripple tolerance: Specified low- and high-frequency ripple currents (160 mA at 120 Hz, 1.6 A at 300 kHz) enable reliable performance in switching and high-frequency environments.
• Extended high-temperature life: Rated for 3000 hours at 125°C, providing predictable endurance for designs exposed to elevated ambient or internal temperatures.
• Assembly-ready packaging: Supplied on embossed carrier tape with moisture-proof packing and compatible with lead‑free reflow up to 260°C, simplifying automated placement and soldering.
• Regulatory compliance: RoHS-compliant construction supports environmental requirements for modern electronic products.
