RKS1H270MCNAHGGS

The RKS1H270MCNAHGGS from Nichicon is a conductive‑polymer aluminum solid electrolytic capacitor in an SMD radial can package. It delivers 27 µF capacitance at 50 V with low equivalent series resistance and high allowable ripple current for high‑frequency power applications.

Designed for applications that require wide temperature capability and extended life at elevated temperature, this part offers a −55 °C to 125 °C operating range and a rated life of 3000 hours at 125 °C, packaged for automated assembly.

Key Features

• Construction — Conductive‑polymer aluminum solid electrolytic, surface‑mount radial can (φ8 × 7.7 mm) configured for SMD assembly.
• Capacitance & tolerance — 27 µF with ±20% tolerance at 120 Hz, 20 °C.
• Rated voltage — 50 V DC.
• Low ESR & high‑frequency performance — ESR 30 mΩ measured at 20 °C/100 kHz and tan δ 0.12 at 20 °C/120 Hz, supporting efficient high‑frequency filtering.
• High ripple current capability — 160 mA at 120 Hz (low frequency) and 1.6 A at 300 kHz (high frequency) for demanding switching applications.
• Leakage current — Specified at 100 µA (after two minutes’ application of rated voltage or per datasheet conditioning).
• High‑temperature endurance — Rated life: 3000 hours at 125 °C under rated voltage conditions.
• Reflow and packaging — SMD type compatible with lead‑free reflow soldering up to 260 °C (per datasheet profile); supplied in embossed carrier taping with moisture‑proof packing for assembly line use.
• Environmental compliance — RoHS compliant.

Typical Applications

• High‑ripple power filtering — Output smoothing and bulk filtering where the 1.6 A high‑frequency ripple rating and low ESR improve ripple handling.
• High‑frequency decoupling — Decoupling at switching nodes and DC‑DC converter outputs where low ESR at 100 kHz and controlled tan δ support stable performance.
• High‑temperature assemblies — Boards and modules operating at elevated ambient temperatures that require rated life performance up to 125 °C for extended periods.

Unique Advantages

• High ripple capability: 1.6 A at 300 kHz allows robust filtering in high‑frequency switching environments.
• Low ESR at high frequency: 30 mΩ (100 kHz) contributes to reduced voltage drop and improved efficiency in power paths.
• Extended high‑temperature life: 3000 hours at 125 °C supports designs needing long‑term reliability under thermal stress.
• SMD reflow compatibility: Designed for lead‑free reflow up to 260 °C and supplied in embossed carrier tape with moisture‑proof packing to streamline automated assembly.
• Predictable leakage characteristics: Specified leakage current (100 µA) and datasheet conditioning provide measurable, repeatable behavior for precision designs.
• RoHS compliance: Meets environmental directive requirements for lead‑free designs.
