RKS1D151MCNAJJGS

The RKS1D151MCNAJJGS from Nichicon is a surface-mount conductive-polymer aluminum electrolytic capacitor in the RKS series. It provides 150 µF capacitance at a 20 V rating and is optimized for general-purpose power applications that require high ripple tolerance and stable performance across a wide temperature range.

Designed for compact assemblies, this radial can SMD package (φ10 × 10 mm) combines low ESR, high allowable ripple current and long endurance—making it suitable for decoupling and smoothing tasks in power conversion and high-frequency circuits.

Key Features

• Capacitance & Voltage: 150 µF nominal capacitance with a rated voltage of 20 V and tolerance of −20% to +20%.
• Low ESR & High-Frequency Performance: ESR of 20 mΩ measured at 100 kHz and a high-frequency ripple current rating of 2.0 A (300 kHz) for improved transient response.
• Low-Frequency Ripple Capability: 200 mA ripple current rating at 120 Hz for bulk smoothing and low-frequency filtering.
• Thermal Range & Endurance: Operating temperature from −55°C to +125°C with a rated lifetime of 3000 hours at 125°C.
• Loss and Leakage: Tangent of loss angle (tan δ) 0.12 (20°C, 120 Hz) and typical leakage current listed as 150 µA.
• Package & Assembly: Surface-mount radial can (φ10 × 10 mm) supplied in embossed carrier taping with moisture-proof packing; compatible with lead-free reflow soldering (peak correspondence up to 260°C as specified in series datasheet).
• Compliance: RKS series documentation indicates RoHS directive compliance (2011/65/EU, (EU)2015/863).

Typical Applications

• DC–DC Converter Output Filtering: Low ESR and 2.0 A high-frequency ripple capability make it suitable for smoothing and stabilizing point-of-load outputs.
• Power Supply Decoupling: Use for bulk decoupling on high-density power rails where compact SMD packaging and wide temperature tolerance are required.
• Embedded and Industrial Electronics: Robust life at elevated temperature and wide operating range support reliable operation in industrial control and embedded systems.
• High-Frequency Power Stages: Designed to handle high allowable ripple current and maintain performance at 100 kHz+ switching frequencies.

Unique Advantages

• High Ripple Handling: 2.0 A high-frequency ripple current rating reduces heating and extends capacitor effectiveness in switching power applications.
• Low ESR for Better Transient Response: 20 mΩ ESR at 100 kHz lowers voltage drop during load transients and improves regulator stability.
• Wide Temperature and Long Life: −55°C to +125°C operating range with 3000 hours endurance at 125°C supports long-term reliability in demanding thermal environments.
• Compact SMD Can Form Factor: φ10 × 10 mm SMD radial can saves board area while delivering high capacitance for compact power designs.
• Reflow-Compatible Packaging: Supplied in embossed carrier taping and moisture-proof packing for automated assembly and lead-free reflow processes.
• Manufacturer Backing: Part of Nichicon’s RKS series, offering documented performance characteristics and datasheet-specified test conditions.
