RKS1J270MCNAHHGS

The RKS1J270MCNAHHGS is a surface-mount conductive polymer aluminum electrolytic capacitor offering 27 µF capacitance at a 63 V rating. Engineered for applications demanding low equivalent series resistance (ESR), high ripple-current capability and extended endurance up to 125 °C, it is suited for power filtering and decoupling in electronics operating in elevated temperature environments.

As an SMD can-style component with embossed carrier taping packaging and lead-free reflow compatibility, the RKS1J270MCNAHHGS integrates into high-density assemblies while delivering stable electrical performance over long service intervals.

Key Features

• Electrical Capacity — 27 µF nominal capacitance with tolerance of −20% to +20% (measured at 20 °C, 120 Hz).
• Rated Voltage — 63 V DC working voltage for mid-voltage power systems and DC link support.
• Low ESR and High-Frequency Performance — ESR of 40 mΩ at 100 kHz and high-frequency ripple current rating of 1.1 A at 300 kHz, enabling effective high-frequency filtering and reduced power loss.
• Ripple Current Capability — 110 mA at 120 Hz (low frequency) and 1.1 A at 300 kHz (high frequency), supporting both bulk and high-frequency ripple handling.
• Leakage and Loss Characteristics — Leakage current specified at 100 µA and tan δ (loss tangent) of 0.12 at 20 °C, 120 Hz for predictable leakage and dissipation behavior.
• High-Temperature Endurance — Rated load life of 3000 hours at 125 °C, supporting long-term operation in hot environments.
• Wide Operating Temperature Range — Specified from −55 °C to +125 °C for broad thermal operating conditions.
• Surface-Mount Can Package — Radial can SMD package, dimensions φ8 × 8.7 mm, and surface-mount land size recommendation of 8.3 × 8.3 mm for compact board layouts.
• Assembly and Compliance — Designed for lead-free reflow soldering (peak 260 °C) and supplied in embossed carrier taping/moisture-proof packing; series-level RoHS compliance is indicated in the datasheet.

Typical Applications

• Power Supply Filtering — Smoothing bulk and switching ripple on DC rails where low ESR and high ripple handling reduce voltage ripple and heat dissipation.
• DC–DC Converters — Output and intermediate filtering in converter stages that require stable capacitance under high ripple and elevated temperatures.
• Industrial Electronics — Power conditioning and decoupling in equipment subjected to wide temperature ranges and continuous operation.
• Telecom and Networking Power Modules — Local energy storage and high-frequency filtering in densely packed power assemblies.

Unique Advantages

• Low ESR for Efficient Filtering: 40 mΩ ESR at 100 kHz delivers lower dissipation and improved high-frequency performance compared with higher-ESR options.
• High Ripple Current Handling: Rated for 1.1 A at 300 kHz and 110 mA at 120 Hz, enabling use in both high-frequency switching and low-frequency smoothing roles.
• Extended High-Temperature Life: 3000 hours endurance at 125 °C supports reliability in thermally demanding applications.
• Compact Surface-Mount Can: φ8 × 8.7 mm SMD package saves board space while allowing robust mounting and automated assembly.
• Reflow-Compatible for Modern Assembly: Designed to withstand lead-free reflow profiles up to 260 °C, simplifying integration into standard SMT processes.
• Predictable Leakage and Loss: Specified leakage current (100 µA) and tan δ (0.12) provide stable behavior for tight power budgets and sensing circuits.
