RKS1E270MCNAHFGS

The RKS1E270MCNAHFGS is a surface-mount conductive‑polymer aluminum electrolytic capacitor in Nichicon’s RKS series. It delivers 27 µF capacitance at 25 V with low equivalent series resistance and high allowable ripple current for compact power‑filtering roles.

Designed for demanding thermal environments, the part supports an operating range of −55°C to 125°C, a rated endurance of 3000 hours at 125°C, and compatibility with lead‑free reflow soldering profiles up to a 260°C peak.

Key Features

• Dielectric / Technology  Conductive‑polymer aluminum solid electrolyte construction for stable performance and low ESR.
• Capacitance & Tolerance  27 µF nominal with −20% to +20% tolerance measured at 20°C, 120 Hz.
• Rated Voltage  25 V DC rating suitable for many low‑voltage power rails.
• Low ESR  30 mΩ equivalent series resistance specified at 20°C, 100 kHz to support high‑frequency decoupling.
• High Ripple Current Handling  160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) for AC and switching applications.
• Leakage Current & Loss  Leakage current ≤100 µA after specified conditioning; tanδ (DF) = 0.12 at 20°C, 120 Hz.
• High‑Temperature Endurance  Load life of 3000 hours at 125°C under rated voltage per RKS series endurance specification.
• Package & Mounting  Surface‑mount radial can (φ8 × 6.7 mm) with recommended land size 8.3 × 8.3 mm; supplied in embossed carrier tape with moisture proof packing.
• Regulatory  RoHS compliant.

Typical Applications

• Switching power supplies  Output and bulk smoothing where low ESR (30 mΩ) and high ripple current (1.6 A @ 300 kHz) reduce voltage ripple and power loss.
• DC‑DC converters  High‑frequency decoupling for converters operating at hundreds of kHz, leveraging the capacitor’s low tanδ and high‑frequency ripple rating.
• Industrial control electronics  Power rail filtering in systems that require long life at elevated temperatures, supported by 3000 hours endurance at 125°C.
• Telecom and network equipment  Local decoupling and filtering on dense boards where compact SMD packaging and reliable high‑temperature performance are needed.

Unique Advantages

• Low ESR for efficient filtering: 30 mΩ at 100 kHz minimizes losses and improves high‑frequency decoupling performance.
• High ripple capability: 1.6 A at 300 kHz and 160 mA at 120 Hz allow use directly on switching nodes and bulk rails without excessive heating.
• Extended high‑temperature life: 3000 hours at 125°C provides durability for thermally demanding applications and reduces replacement frequency.
• Reflow compatible SMD package: Designed for lead‑free reflow profiles (peak up to 260°C), enabling automated assembly and reliable solder joints.
• Compact radial can footprint: φ8 × 6.7 mm size balances capacitance and board space for dense layouts.
• RoHS compliant: Meets RoHS requirements for use in compliant product designs.
