RKS1E470MCNAHGGS

The RKS1E470MCNAHGGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor offering 47 µF capacitance at a 25 V rating. It is engineered for applications that demand high allowable ripple current, low ESR at high frequency, and sustained operation at elevated temperatures.

Key attributes include a wide operating temperature range from −55 °C to +125 °C and a rated load life of 3000 hours at 125 °C, making the part suitable for compact SMD power designs where long-term thermal reliability and high-frequency performance are required.

Key Features

• Electrical Performance — 47 µF nominal capacitance with ±20% tolerance and a rated voltage of 25 V; tanδ (DF) specified at 0.12 (20 °C, 120 Hz).
• Low ESR & High-Frequency Capability — ESR of 30 mΩ measured at 20 °C / 100 kHz supports high-frequency decoupling; high-frequency ripple current capability rated at 1.6 A (300 kHz).
• Ripple Current Handling — Low-frequency ripple current of 160 mA at 120 Hz and high-frequency ripple current of 1.6 A at 300 kHz for robust AC stress performance.
• Thermal and Endurance Performance — Rated for operation from −55 °C to +125 °C with a guaranteed load life of 3000 hours at 125 °C.
• Surface-Mount Package — Radial can SMD package (φ8 × 7.7 mm) designed for reflow; compatible with lead-free reflow soldering conditions up to a 260 °C peak as specified.
• Leakage and Reliability — Leakage current specified at 100 µA (with the datasheet conditioning method noted) and endurance/shelf-life behavior defined for high-reliability applications.
• Production & Packaging — Available in embossed carrier taping with moisture-proof packing for automated SMD assembly.
• Regulatory — Series-level datasheet indicates compliance with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• High-ripple power circuits — Use where low ESR (30 mΩ) and high allowable ripple current (1.6 A at 300 kHz) improve stability and reduce heating under AC stress.
• High-temperature SMD assemblies — Designed for assemblies that require sustained operation up to 125 °C and reflow-capable SMD mounting.
• Compact power modules — Small φ8 × 7.7 mm can-style SMD package enables high capacitance density in space-constrained PCB footprints.

Unique Advantages

• Long high-temperature load life: 3000 hours at 125 °C provides defined endurance for designs exposed to elevated operating temperatures.
• High-frequency performance: 30 mΩ ESR at 100 kHz and 1.6 A ripple capability at 300 kHz support effective decoupling at switching frequencies.
• Reflow-capable SMD form factor: Radial can SMD design and embossed carrier taping simplify automated assembly and throughput.
• Controlled leakage: Leakage current rated at 100 µA with conditioning guidance in the datasheet supports predictable behavior in biased circuits.
• Robust thermal range: −55 °C to +125 °C rating covers a wide set of industrial and commercial temperature environments.
