RNL1E471MDS1

The RNL1E471MDS1 is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can, providing 470 µF capacitance at a 25 V rating. It delivers low ESR and high ripple current capability in a compact φ8×16 mm package, intended for general-purpose electronic designs that require reliable bulk capacitance with high-frequency performance.

Key Features

• Core Electrical 470 µF rated capacitance with ±20% tolerance at 120 Hz, 20°C and a rated voltage of 25 V.
• Low ESR & High-Frequency Performance ESR of 10 mΩ measured at 20°C/100 kHz and a high-frequency ripple current rating of 5.8 A at 300 kHz, enabling effective handling of fast switching and high-frequency ripple.
• Ripple Current (Low & High Frequency) Low-frequency ripple current of 580 mA at 120 Hz and a high-frequency ripple current of 5.8 A at 300 kHz (frequency coefficient 1.00 at 300 kHz or more).
• Thermal & Reliability Rated for operation from −55°C to +105°C with a load life (endurance) of 2000 hours at 105°C and rated voltage.
• Leakage & Loss Leakage current specified at 1175 µA (measured after 2 minutes at 20°C) and tan δ of 0.12 at 20°C/120 Hz.
• Mechanical & Packaging Radial lead mounting with φ8×16 mm case size, lead spacing 3.5 mm ±0.5 mm, and bulk/bag packing (no terminal forming) for simple through-hole integration.
• Compliance RoHS compliant as specified in the product documentation.

Typical Applications

• Power supply decoupling — Uses the 470 µF capacitance and low ESR (10 mΩ at 100 kHz) to support high ripple environments and stabilize voltage rails.
• High-frequency switching power — The 5.8 A high-frequency ripple current rating and frequency coefficient data make it suitable for circuits with fast switching activity.
• General-purpose electronic equipment — Designed for general-purpose applications requiring robust bulk capacitance across −55°C to +105°C operating range.

Unique Advantages

• Low ESR at 100 kHz: 10 mΩ ESR improves high-frequency performance and minimizes heat generation under ripple conditions.
• High ripple current capability: 5.8 A rating at 300 kHz supports demanding switching supplies and reduces the need for multiple parallel components.
• Wide operating temperature: −55°C to +105°C rating supports deployment across varied thermal environments.
• Long endurance at high temperature: 2000 hours at 105°C under rated voltage provides predictable life performance for thermal-stressed designs.
• Radial lead format: Through-hole radial leads with 3.5 mm spacing simplify insertion and mechanical retention for wave or hand soldering processes.
• RoHS compliant: Meets environmental directive requirements as documented for the RNL series.
