RKS1V151MCNAJLGS

The RKS1V151MCNAJLGS is a surface-mount conductive-polymer aluminum solid electrolytic capacitor designed for general-purpose power applications requiring high capacitance, low ESR and sustained performance at elevated temperatures. It delivers 150 µF at 35 V with a construction optimized for high ripple current handling and long load life.

Key value comes from a combination of low equivalent series resistance (20 mΩ at 100 kHz), high allowable ripple current (2.0 A at high frequency), and 3000-hour endurance at 125°C, making it suitable for circuits where robust filtering, decoupling and energy storage are required under thermal stress.

Key Features

• Capacitance & Voltage — 150 µF rated capacitance with ±20% tolerance at 120 Hz, 20°C; rated for 35 V operation.
• Low ESR & Loss — ESR of 20 mΩ measured at 100 kHz and tanδ (DF) of 0.12 measured at 20°C, 120 Hz, enabling efficient high-frequency performance.
• High Ripple Current Capability — Low-frequency ripple current of 200 mA (120 Hz) and high-frequency ripple current of 2.0 A (300 kHz) for demanding power-filtering tasks.
• Long Endurance — Rated life of 3000 hours at 125°C under rated voltage, supporting long-term reliability in high-temperature environments.
• Wide Operating Temperature Range — Designed for operation from −55°C to +125°C to accommodate a broad range of thermal conditions.
• Surface-Mount Package & Packing — Radial can SMD (φ10×12.4L) in embossed carrier taping with moisture-proof packing for automatic placement and production handling.
• Leakage Current — Specified leakage current of 262 µA after 2 minutes’ application of rated voltage.
• RoHS Compliant — Manufactured in compliance with RoHS directive requirements.

Typical Applications

• General-purpose power filtering — 150 µF capacitance with low ESR supports smoothing and decoupling in power supply rails and DC–DC converter outputs.
• High-frequency decoupling — Low ESR at 100 kHz and high-frequency ripple current rating make it suitable for high-speed switching regulator support.
• High-temperature electronics — 3000-hour endurance at 125°C targets systems that require reliable operation under sustained elevated temperatures.

Unique Advantages

• High ripple-handling performance: 2.0 A high-frequency ripple rating combined with 20 mΩ ESR reduces thermal stress and improves filtering effectiveness in switching applications.
• Proven thermal endurance: 3000 hours at 125°C under rated voltage provides predictable aging behavior and supports longer maintenance intervals.
• Compact SMD form factor: Radial can SMD package and embossed carrier taping enable automated placement while preserving high capacitance in a small footprint.
• Stable AC characteristics: Specified tanδ and DF measurement conditions (20°C, 120 Hz) provide clear performance expectations for AC and ripple applications.
• Manufacturing-ready packaging: Moisture-proof, embossed carrier taping simplifies inventory handling and reflow assembly process compatibility up to 260°C peak.
