RKS1E151MCNAJLGS

The RKS1E151MCNAJLGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 150 µF capacitance at a 25 V rating. It combines low equivalent series resistance and high allowable ripple current with a compact radial can SMD package, suited for general-purpose electronic designs that require stable filtering and decoupling across a wide temperature range.

Designed for reliability in elevated-temperature environments, this part delivers a long endurance profile (3000 hours at 125°C) and is supplied in embossed carrier taping with moisture-proof packing for SMT assembly.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a rated voltage of 25 V and a tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Low Loss Tangent — tanδ of 0.12 measured at 20°C, 120 Hz for predictable AC behavior in filtering applications.
• Low ESR — 20 mΩ ESR specified at 20°C/100 kHz, enabling efficient high-frequency performance and reduced power dissipation.
• High Ripple Current Capability — supports 200 mA at 120 Hz (low frequency) and 2 A at 300 kHz (high frequency) for demanding ripple and decoupling loads.
• Leakage Current — specified leakage current of 187 µA for predictable bias current considerations.
• Thermal & Endurance — rated operating temperature from -55°C to +125°C with a load-life endurance of 3000 hours at 125°C.
• Package & Mounting — radial, can-style SMD package sized φ10 × 12.4 mm (L: 1.24 × D: 1.00 cm) for surface-mount assembly; shipped in embossed carrier taping with moisture-proof packing.
• RoHS Compliant — meets applicable RoHS requirements as stated in product data.
• Reflow Compatibility — designed for lead-free reflow soldering processes up to the specified peak temperature in the datasheet.

Typical Applications

• General-purpose power filtering — bulk smoothing and AC ripple reduction in power supply rails where 150 µF and low ESR are required.
• High-frequency decoupling — use near power converters and switching regulators to exploit the low ESR at 100 kHz and 2 A high-frequency ripple rating.
• Embedded and industrial electronics — long endurance at 125°C and a wide operating temperature range make it suitable for robust general-purpose designs.

Unique Advantages

• High ripple tolerance: 2 A high-frequency ripple current and 200 mA low-frequency ripple current support demanding decoupling and smoothing tasks.
• Low ESR for stable operation: 20 mΩ ESR at 100 kHz reduces losses and heat generation in high-frequency circuits.
• Thermal endurance: 3000 hours at 125°C provides long-term stability for elevated-temperature applications.
• Compact SMD can package: φ10 × 12.4 mm radial SMD format offers a space-efficient solution for surface-mount assemblies while maintaining capacitance density.
• Predictable leakage and loss characteristics: specified leakage current (187 µA) and tanδ (0.12 at 20°C/120 Hz) simplify design margining and thermal budgeting.
• Supply chain friendly packaging: embossed carrier taping with moisture-proof packing supports automated SMT lines and inventory handling.
