RNL1E331MDS1

The RNL1E331MDS1 is a Nichicon RNL series conductive polymer aluminum solid electrolytic capacitor in a radial-lead can. It delivers 330 µF capacitance at a 25 V rating in a compact φ8×16L package with 3.5 mm lead spacing.

Designed for general-purpose electronic designs, this component combines low ESR and high ripple-current capability with a wide operating temperature range (−55 °C to 105 °C), making it suitable where reliable bulk capacitance and high-frequency performance are required.

Key Features

• Construction Conductive polymer aluminum solid electrolytic capacitor in a radial lead can (RNL series).
• Capacitance & Voltage 330 µF nominal capacitance at a 25 V rated voltage with tolerance −20% to +20%.
• Low ESR ESR of 10 mΩ measured at 20 °C / 100 kHz, supporting low-loss operation at high frequencies.
• High Ripple Current Rated ripple currents of 580 mA at 120 Hz and 5.8 A at 300 kHz (high-frequency condition), enabling effective AC ripple handling.
• Leakage Current Specified leakage current of 825 µA (measured after 2 minutes at 20 °C under rated voltage conditions).
• Reliability / Endurance Load life: 2000 hours at 105 °C under rated voltage conditions.
• Environmental & Compliance RoHS compliant.
• Mechanical Compact dimensions φ8×16L, lead spacing 3.5 mm (±0.5 mm tolerance); available in bulk or bag packing; mass production status.

Typical Applications

• General-purpose power filtering Bulk decoupling and ripple smoothing on power rails in general-purpose electronic circuits.
• High-frequency decoupling Low ESR and specified 100 kHz ESR measurement make this capacitor suitable for high-frequency decoupling tasks in power electronics designs.
• Power supply modules Use where compact, high-capacitance radial-lead components are required for local energy storage and transient suppression.

Unique Advantages

• Low-loss high-frequency performance: 10 mΩ ESR at 100 kHz minimizes series losses and supports efficient decoupling in high-frequency environments.
• High ripple handling: Rated ripple current up to 5.8 A at 300 kHz reduces thermal stress in applications with high AC components on the DC rail.
• Wide temperature tolerance: −55 °C to 105 °C operation enables use across a broad range of ambient conditions without changing component selection.
• Compact radial-lead form factor: φ8×16L can with 3.5 mm lead spacing provides a high-capacitance solution for through-hole designs where board space is limited.
• Manufacturing readiness: Available in bulk and bag packing and listed as mass production, facilitating procurement and assembly planning.
