RKS1H270MCNAFGGS

The RKS1H270MCNAFGGS is a surface‑mount conductive polymer aluminum solid electrolytic capacitor offering 27 µF capacitance at a 50 V rating. It combines low ESR and high allowable ripple current with long endurance for demanding thermal environments.

Designed for applications that require compact SMD power components, this part delivers measurable performance attributes—low ESR (40 mΩ at 100 kHz), high frequency ripple capability (1.1 A at 300 kHz), and a rated life of 3000 hours at 125°C—while being RoHS compliant and compatible with lead‑free reflow processes.

Key Features

• Capacitance & Voltage — 27 µF nominal capacitance with a rated voltage of 50 V and a capacitance tolerance of −20% to +20% at 120 Hz, 20°C.
• Conductive Polymer Electrolyte — Solid conductive polymer construction for improved ESR stability and leakage characteristics compared with conventional liquid electrolytes.
• Low ESR — ESR of 40 mΩ measured at 20°C, 100 kHz, supporting efficient high‑frequency operation and reduced power loss.
• High Ripple Current Capacity — Low‑frequency ripple current of 110 mA at 120 Hz and high‑frequency ripple current of 1.1 A at 300 kHz for robust power handling in switching environments.
• Wide Temperature & Long Life — Rated operating range from −55°C to +125°C with a load life specification of 3000 hours at 125°C and rated voltage.
• Leakage & Dissipation — Leakage current specified at 100 µA and tangent of loss angle (tan δ) of 0.12 (measured at 20°C, 120 Hz) to support predictable DC bias behavior and dissipation.
• SMD Package & Reflow Compatibility — Radial can SMD package with dimensions φ6.3 × 7.7 mm (D × L) and surface mount land size 6.6 × 6.6 mm; packaged in embossed carrier tape with moisture proof packing and compatible with lead‑free reflow conditions (peak 260°C per series data).
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power rail filtering: Bulk decoupling and smoothing on 50 V rails where low ESR and measurable ripple current capability reduce voltage ripple and thermal stress.
• Switching power supplies: Output stage and intermediate bus decoupling benefiting from the capacitor’s high‑frequency ripple current rating and low ESR.
• Power modules and DC/DC converters: Compact SMD mounting and high temperature endurance support dense power electronics assemblies subject to elevated operating temperatures.

Unique Advantages

• High temperature endurance: 3000‑hour life at 125°C ensures predictable aging and long service life in thermally demanding designs.
• Measurable low ESR: 40 mΩ at 100 kHz minimizes conduction losses and supports efficient high‑frequency operation.
• Strong ripple handling: 1.1 A at 300 kHz and 110 mA at 120 Hz give designers clear limits for thermal and ripple budgeting.
• Compact SMD form factor: φ6.3 × 7.7 mm can size enables space‑efficient placement in modern PCB power layouts.
• Manufacturing ready: Embossed carrier taping with moisture proof packing and reflow compatibility simplify SMT assembly flow.
• Predictable leakage and dissipation: Specified leakage current (100 µA) and tan δ (0.12) support margin calculations for bias and standby conditions.
