RKS1E271MCNAJJGS

The RKS1E271MCNAJJGS from Nichicon is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 270 µF capacitance at a 25 V rating. It combines low ESR and high ripple-current capability in a compact φ10 × 10 mm SMD can designed for general-purpose power applications.

Engineered for reliability across a wide temperature range (−55 °C to 125 °C) with a 3000-hour endurance at 125 °C, this part targets designs that require stable bulk capacitance, low-loss performance, and automated assembly compatibility.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance at 25 V with tolerance −20% to +20% for predictable energy storage and smoothing.
• Low loss (tan δ) — tanδ = 0.12 measured at 20 °C, 120 Hz, supporting efficient operation in AC ripple environments.
• Low ESR — 20 mΩ ESR measured at 20 °C, 100 kHz, minimizing conduction losses and heat generation in high-frequency circuits.
• High ripple-current capability — 200 mA at 120 Hz (low frequency) and 2000 mA at 300 kHz (high frequency) to handle dynamic load conditions.
• Leakage current — Specified leakage current of 337 µA for predictable standby and bias performance.
• High-temperature endurance — Rated for 3000 hours at 125 °C, delivering long-term stability in elevated-temperature environments.
• Surface-mount package — φ10 × 10L radial can SMD package supplied in embossed carrier tape with moisture-proof packing for pick-and-place assembly.
• RoHS compliant — Complies with RoHS requirements for materials compliance.

Typical Applications

• Power supply smoothing: Bulk capacitance and low ESR provide effective filtering and energy storage for switching power supplies and regulators.
• High-frequency decoupling: Low ESR and high ripple-current handling make this capacitor suitable for decoupling in high-frequency power stages.
• Compact SMD power modules: The φ10 × 10 mm SMD can and embossed carrier tape packaging support automated assembly of space-constrained modules.

Unique Advantages

• High ripple tolerance: Rated for 200 mA (120 Hz) and 2000 mA (300 kHz), enabling use in demanding ripple environments.
• Low equivalent series resistance: 20 mΩ at 100 kHz reduces power loss and heat under AC conditions.
• Extended high-temperature life: 3000 hours at 125 °C provides proven endurance for designs exposed to elevated temperatures.
• Compact SMD form factor: φ10 × 10L can allows high capacitance in a small footprint suitable for automated PCB assembly.
• Predictable leakage behavior: Specified leakage current of 337 µA for reliable bias and standby calculations.
• Assembly-ready packaging: Embossed carrier taping with moisture-proof packing simplifies handling and feed for pick-and-place lines.
