RKS1E470MCNAJJGS

The RKS1E470MCNAJJGS is a surface-mount conductive polymer aluminum electrolytic capacitor offering 47 µF capacitance at a 25 V rating. Engineered for board-level power decoupling and filtering, it delivers low equivalent series resistance (ESR) and high allowable ripple current in a compact φ10 × 10 mm SMD can.

Designed for general-purpose electronic equipment, this part combines a wide operating temperature range (−55 °C to 125 °C) and extended load life (3000 hours at 125 °C) to support demanding thermal and ripple conditions on power rails.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of −20% to +20% (at 120 Hz, 20 °C).
• Conductive Polymer Dielectric — Solid conductive polymer construction providing stable performance and reduced losses compared to conventional electrolytics; tanδ specified at 0.12 (20 °C, 120 Hz).
• Low ESR & High Ripple Handling — ESR of 20 mΩ measured at 20 °C/100 kHz, with allowable ripple current of 200 mA at 120 Hz (low-frequency) and 2.0 A at 300 kHz (high-frequency) for effective high-frequency decoupling.
• Leakage Current — Leakage current specified at 100 µA, supporting predictable bias behavior after voltage application.
• Thermal Endurance — Rated operating temperature from −55 °C to 125 °C with a rated load life of 3000 hours at 125 °C, designed to maintain capacitance and ESR within specified endurance limits.
• SMD Package & Assembly Ready — Radial can SMD package (φ10 × 10 mm) supplied in embossed carrier tape with moisture-proof packing; compatible with lead-free reflow profiles up to a 260 °C peak per the series datasheet.
• Standards Compliance — Series datasheet indicates compliance with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply decoupling — Low ESR and high ripple current capability support stable decoupling of SMD power rails in compact board layouts.
• Point-of-load filtering — High-frequency ripple current rating (2.0 A at 300 kHz) enables effective local filtering for switching regulators and power modules.
• General-purpose electronic equipment — Durable temperature range and long load life make this capacitor suitable for a wide range of industrial and commercial board-level designs requiring reliable bulk and decoupling capacitance.

Unique Advantages

• High ripple tolerance: 2.0 A high-frequency ripple current rating reduces heating and improves reliability on fast switching power rails.
• Low loss at high frequency: 20 mΩ ESR at 100 kHz and tanδ specified at 0.12 support efficient high-frequency performance.
• Extended high-temperature life: 3000-hour endurance at 125 °C provides predictable long-term behavior in thermally demanding environments.
• SMD-ready packaging: Embossed carrier taping and moisture-proof packing simplify pick-and-place and reflow assembly workflows.
• Predictable leakage behavior: Leakage current spec (100 µA) and conditioning guidance in the datasheet help ensure predictable bias recovery after voltage application.
