RKS1V270MCNAHHGS

The RKS1V270MCNAHHGS from Nichicon is a conductive polymer aluminum solid electrolytic surface-mount capacitor with 27 µF capacitance and a 35 V rating. It combines low ESR and high allowable ripple current with a long-life specification, making it suitable for high-frequency power filtering and decoupling in compact, high-temperature designs.

Designed for SMD assembly, embossed carrier taping with moisture-proof packing supports automated production. Key value comes from low loss (tan δ), low ESR, and extended endurance at elevated temperature for robust operation in demanding environments.

Key Features

• Capacitance & Voltage — 27 µF capacitance rated at 35 V with ±20% tolerance for stable bulk and decoupling performance.
• Low ESR & Low Loss — ESR of 30 mΩ measured at 100 kHz (20°C) and tan δ of 0.12 (20°C, 120 Hz) to support efficient high-frequency filtering and reduced thermal dissipation.
• High Ripple Capability — Low-frequency ripple current 160 mA (120 Hz) and high-frequency ripple current 1.6 A (300 kHz) for demanding switching regulator and converter applications.
• Wide Temperature & Long Life — Rated for operation from −55°C to 125°C with endurance of 3000 hours at 125°C (rated voltage), enabling reliable use in high-temperature systems.
• SMD Package & Assembly — Radial can SMD (φ8 × 8.7 mm) designed for surface-mount placement; compatible with lead-free reflow up to 260°C peak per series datasheet guidance.
• Manufacturing Ready — Supplied in embossed carrier taping with moisture-proof packing to support automated pick-and-place assembly and moisture-sensitive handling.
• Environmental Compliance — RoHS compliant as indicated in product data.

Typical Applications

• DC–DC converter output smoothing — Low ESR and high-frequency ripple handling make this part suitable for output filtering on switching regulators and point-of-load modules.
• Power supply decoupling — Use for bulk decoupling and transient suppression in industrial and telecom power subsystems operating across a wide temperature range.
• Embedded control and computing modules — Compact SMD can and automated tape packaging simplify integration into board-level power networks for embedded systems.
• High-temperature electronics — Endurance specified at 125°C for 3000 hours supports applications where elevated operating temperatures are expected.

Unique Advantages

• High ripple tolerance: 1.6 A at 300 kHz and 160 mA at 120 Hz provide robust performance in both switching and low-frequency environments, reducing voltage ripple on power rails.
• Low ESR for improved efficiency: 30 mΩ ESR at 100 kHz reduces I²R losses and heat generation in high-frequency circuits.
• Long-term thermal endurance: 3000-hour life at 125°C under rated voltage ensures component longevity in thermal-stressed designs.
• SMD-friendly packaging: Embossed carrier taping and moisture-proof packing streamline automated assembly and storage handling.
• Compact radial can footprint: φ8 × 8.7 mm size provides a balance of capacitance and space efficiency for dense board layouts.
• RoHS compliant: Meets environmental directive requirements for restricted substances as listed in the product data.
