RKS1E151MCNAHJGS

The RKS1E151MCNAHJGS is a surface-mount conductive polymer aluminum electrolytic capacitor designed for general-purpose power electronics where high capacitance, low ESR and reliable high-temperature endurance are required. Its 150 µF capacitance at 25 V, combined with low equivalent series resistance and high allowable ripple current, makes it suitable for smoothing, decoupling and bulk energy storage in compact SMD designs.

Packaged in a φ8 × 10 mm can with embossed carrier taping and moisture-proof packing, this part is available for mass production and supports demanding thermal environments with an operating range from −55 °C to 125 °C and a rated life of 3000 hours at 125 °C.

Key Features

• Capacitance & Voltage: 150 µF rated at 25 V, with a capacitance tolerance of ±20% (specified as -20% to 20%).
• Conductive Polymer Electrolyte: Solid conductive polymer construction for stable performance and predictable end-of-life characteristics.
• Low ESR: 27 mΩ specified at 20 °C, 100 kHz, supporting lower loss and improved efficiency in high-frequency circuits.
• Tangent of Loss Angle (tan δ): 0.12 at 20 °C, 120 Hz, providing a measurable dissipation factor for design verification.
• High Allowable Ripple Current: 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) to support switching power supplies and high-frequency decoupling.
• Leakage Current: 187 µA specified (measurement after rated voltage conditions per datasheet guidance).
• Extended Temperature & Life: Rated for −55 °C to 125 °C with a 3000-hour endurance rating at 125 °C.
• SMD Can Package & Tape Packaging: φ8 × 10 mm radial can (SMD) offered in embossed carrier taping with moisture-proof packing for production assembly.
• RoHS Compliance (series-level): Series datasheet indicates compliance with the RoHS directive.

Typical Applications

• Power Supply Filtering: Bulk smoothing and output filtering in DC–DC converters and linear regulators where low ESR and high ripple handling reduce voltage ripple.
• High-Frequency Decoupling: Local energy storage for switching regulators and high-frequency power stages that require fast transient support and low loss at 100 kHz–300 kHz ranges.
• Embedded & Industrial Electronics: General-purpose decoupling and bulk capacitance in compact SMD assemblies operating across a wide temperature range (−55 °C to 125 °C).

Unique Advantages

• High ripple tolerance: Dual-rated ripple currents (160 mA at 120 Hz and 1.6 A at 300 kHz) enable reliable performance in both low- and high-frequency power circuits.
• Low thermal and frequency loss: 27 mΩ ESR at 100 kHz and a tan δ of 0.12 at 120 Hz reduce dissipation and help maintain efficiency in compact power systems.
• Robust high-temperature endurance: 3000 hours rated life at 125 °C provides predictable longevity in thermally demanding applications.
• Compact SMD can format: φ8 × 10 mm radial can with embossed carrier taping and moisture-proof packing simplifies automated assembly and inventory handling.
• Clear leakage and tolerance specifications: Specified leakage current (187 µA) and ±20% capacitance tolerance support deterministic power-budgeting and design validation.
