RKS1J270MCNAHFGS

The RKS1J270MCNAHFGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor delivering 27 µF at 63 V in a compact φ8 × 6.7 mm can-style SMD package. It is designed for applications that require low ESR, high allowable ripple current, and extended operating life at elevated temperatures.

With a rated temperature range of –55 °C to 125 °C and an endurance specification of 3000 hours at 125 °C, this part targets designs where thermal robustness, high-frequency performance, and reliable long-term operation are priorities.

Key Features

• Capacitance & Voltage — 27 µF rated capacitance with a 63 V rated voltage and a tolerance of −20% to +20%.
• Conductive Polymer Electrolyte — Solid conductive polymer construction for stable performance and measurable leakage characteristics (100 µA specified).
• Low ESR & High-Frequency Performance — ESR of 40 mΩ at 20 °C / 100 kHz and specified high-frequency ripple capability of 1.1 A at 300 kHz for demanding AC conditions.
• Ripple Current Capability — Low-frequency ripple current rated at 110 mA (120 Hz) and high-frequency ripple current rated at 1.1 A (300 kHz), enabling effective smoothing in switching environments.
• High Temperature Endurance — Rated life of 3000 hours at 125 °C; meets endurance and damping requirements described in the series datasheet.
• SMD Package & Reflow Compatible — Radial can-style SMD package (φ8 × 6.7 mm), surface-mount land size 8.3 × 8.3 mm, and designed for lead‑free reflow (peak up to 260 °C per datasheet guidance).
• Reliability Metrics — Specified tan δ (DF) of 0.12 at 20 °C, 120 Hz and controlled leakage current behavior after voltage application.
• Packaging — Supplied in embossed carrier taping with moisture-proof packing for automated assembly and handling.
• RoHS Compliant — Conforms to RoHS requirements as stated in the product information.

Typical Applications

• High-frequency power circuits — Use where low ESR (40 mΩ at 100 kHz) and high-frequency ripple handling (1.1 A at 300 kHz) are required for stable filtering and decoupling.
• Switching regulator outputs — Suitable for output smoothing in switching converters due to its high ripple current capability and conductive polymer construction.
• Thermally demanding electronics — Applicable in assemblies that must operate reliably up to 125 °C for long durations (3000 hours endurance at 125 °C).

Unique Advantages

• High ripple tolerance: Rated ripple currents of 110 mA (120 Hz) and 1.1 A (300 kHz) reduce voltage ripple in both low- and high-frequency environments.
• Low ESR for high-frequency stability: 40 mΩ ESR at 100 kHz supports improved power delivery and reduced losses in high-speed circuits.
• Extended high-temperature life: 3000 hours endurance at 125 °C provides predictable aging behavior for designs exposed to elevated temperatures.
• Compact SMD form factor: φ8 × 6.7 mm can-style SMD package and standardized land pattern (8.3 × 8.3 mm) simplify PCB layout for space-constrained designs.
• Assembly-ready packaging: Embossed carrier taping with moisture-proof packing enables reliable automated placement and storage prior to assembly.
• Controlled leakage and DF characteristics: Specified leakage current (100 µA) and tan δ (0.12 at 20 °C, 120 Hz) enable predictable electrical performance.
