RKS1D151MCNAHFGS

The RKS1D151MCNAHFGS is a surface‑mount conductive polymer aluminum electrolytic capacitor with a nominal capacitance of 150 µF and a rated voltage of 20 V. It is engineered for SMD assemblies that require low equivalent series resistance (ESR), high allowable ripple current, and extended endurance at elevated temperatures.

Key attributes include a wide operating temperature range of −55 °C to 125 °C, a rated lifetime of 3000 hours at 125 °C, low ESR (30 mΩ at 100 kHz), and reflow compatibility up to a 260 °C peak. These characteristics make it suitable for SMD high‑ripple‑current and high‑temperature endurance applications.

Key Features

• Capacitance and Voltage — 150 µF nominal capacitance with a rated voltage of 20 V and a capacitance tolerance of −20% to +20% at 20 °C, 120 Hz.
• Low ESR and High‑Frequency Performance — ESR specified at 30 mΩ (measured at 20 °C, 100 kHz) and a high‑frequency ripple current capability of 1.6 A (300 kHz), supporting low‑loss decoupling and filtering at high switching frequencies.
• Low‑Frequency Ripple Handling — Rated low‑frequency ripple current of 160 mA at 120 Hz for bulk ripple suppression and smoothing applications.
• Thermal Endurance — Rated lifetime of 3000 hours at 125 °C and an operating temperature range from −55 °C to 125 °C, enabling sustained operation in elevated‑temperature environments.
• Reflow and Assembly — SMD radial can package designed for lead‑free reflow soldering (preheat and 260 °C peak profile supported) and supplied in embossed carrier taping with moisture‑proof packing for automated assembly.
• Leakage and Dissipation — Leakage current specified at 150 µA and tan δ (loss tangent) of 0.12 (measured at 20 °C, 120 Hz), providing predictable dissipation characteristics for power designs.
• Compact SMD Form Factor — Case size φ8 × 6.7 mm (length × diameter) with recommended land size of 8.3 × 8.3 mm for surface mounting in space‑constrained layouts.
• RoHS Compliance — Series-level datasheet indicates compliance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• SMD high‑ripple‑current circuits — For surface‑mount designs that demand capacitors with high allowable ripple current and low ESR for ripple suppression and energy buffering.
• Elevated‑temperature assemblies — Suitable for assemblies and modules that require stable capacitance and performance after prolonged operation at temperatures up to 125 °C (3000 h endurance).
• High‑frequency decoupling — Used where low ESR at high frequencies is needed to reduce voltage ripple and improve regulator stability.
• Automated SMD production — Supplied in embossed carrier taping and moisture‑proof packing for reliable pick‑and‑place and reflow processes.

Unique Advantages

• High ripple tolerance: Rated for 1.6 A at 300 kHz (high frequency) and 160 mA at 120 Hz (low frequency), enabling effective ripple management across switching and line frequencies.
• Low ESR for improved efficiency: 30 mΩ ESR at 100 kHz reduces conduction losses and heat generation in high‑frequency power stages.
• Long high‑temperature life: 3000 hours at 125 °C provides predictable lifetime performance in thermally demanding designs.
• Reflow‑compatible SMD package: Designed for lead‑free reflow up to 260 °C peak, simplifying integration into standard surface‑mount manufacturing flows.
• Compact footprint: φ8 × 6.7 mm case and recommended 8.3 × 8.3 mm land pattern balance capacitance with board space efficiency.
• Controlled leakage and loss: Specified leakage current (150 µA) and tan δ (0.12) enable reliable power budgeting and thermal planning.
