RKS1D271MCNAHHGS

The RKS1D271MCNAHHGS is a surface‑mount conductive polymer aluminum electrolytic capacitor delivering 270 µF at 20 V in a compact can‑style SMD package. It combines low ESR and high allowable ripple current with extended high‑temperature endurance for demanding power‑handling applications.

Designed for board‑level use where ripple handling, long life at elevated temperature, and reliable surface‑mount assembly are required, this part suits compact power conversion and decoupling roles in electronics that operate across a wide temperature range.

Key Features

• Capacitance & Tolerance — 270 µF nominal capacitance with tolerance of -20% to +20% (measured at 120 Hz, 20 °C), providing predictable bulk energy storage for power rails.
• Rated Voltage — 20 V DC rating suitable for common low‑voltage power rails.
• Low ESR and High Ripple Capability — ESR of 30 mΩ at 20 °C/100 kHz, low‑frequency ripple current 160 mA (120 Hz) and high‑frequency ripple current 1.6 A (300 kHz), enabling effective filtering and transient handling.
• High‑Temperature Endurance — Rated operating range -55 °C to 125 °C with a rated load life of 3000 hours at 125 °C, supporting extended reliability in elevated‑temperature environments.
• Dielectric & Loss — Conductive polymer construction with tan δ (loss tangent) of 0.12 (20 °C, 120 Hz), balancing low loss with stable electrical characteristics.
• Surface‑Mount Packaging — Can‑style SMD package (φ8 mm) supplied in embossed carrier taping with moisture‑proof packing for automated assembly and moisture sensitivity control.
• Leakage Current — Specified leakage current of 270 µA, supporting low standby loss where applicable.
• RoHS Compliance — Manufactured in compliance with RoHS requirements.

Typical Applications

• Power supplies and DC‑DC converters — Bulk smoothing and decoupling where 1.6 A high‑frequency ripple handling and low ESR improve output stability and transient response.
• Point‑of‑load decoupling — Local energy reservoir for regulators and converters in compact assemblies requiring surface‑mount components.
• Industrial electronics — Power filtering and energy storage in boards that operate across a wide temperature range up to 125 °C and require long life.

Unique Advantages

• High ripple tolerance: Combines low ESR (30 mΩ) with specified high‑frequency ripple current (1.6 A) to reduce voltage ripple and heat generation on power rails.
• Extended high‑temperature life: Rated for 3000 hours at 125 °C, delivering sustained capacitance and ESR stability in elevated‑temperature applications.
• Compact SMD can package: φ8 mm can‑style surface‑mount form factor enables high capacitance in a space‑efficient footprint for automated assembly.
• Predictable electrical characteristics: Defined tan δ and leakage current specs allow accurate margining in filter and decoupling designs.
• Assembly‑ready packaging: Supplied in embossed carrier taping with moisture‑proof packing for reliable high‑temperature reflow processing.
