RNL1E102MDS1

The RNL1E102MDS1 from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a radial-lead can package. It delivers 1000 µF capacitance with a 25 V rating and polarized radial-lead mounting for general-purpose electronic designs.

Designed for applications that demand high capacitance, low ESR and elevated ripple handling, this part combines a compact φ10×20 mm can, low ESR (10 mΩ at 20°C/100 kHz) and high-frequency ripple capability (8.1 A at 300 kHz) with a wide operating range from −55°C to 105°C and a rated life of 2000 hours at 105°C.

Key Features

• Core Type & Capacitance Conductive polymer aluminum solid electrolytic capacitor with 1000 µF nominal capacitance and ±20% tolerance.
• Voltage Rating Rated for 25 V operation.
• Low ESR / High-frequency Performance ESR of 10 mΩ measured at 20°C/100 kHz supports low-loss operation; high-frequency ripple current rating of 8.1 A at 300 kHz enables use with fast-switching power converters.
• Ripple Capability (Low & High Frequency) Rated ripple currents: 810 mA at 120 Hz and 8.1 A at 300 kHz, providing flexibility across low- and high-frequency power stages.
• Loss Tangent tanδ = 0.12 measured at 20°C, 120 Hz, indicating controlled dielectric loss for stable performance.
• Reliability & Lifetime Endurance rated 2000 hours at 105°C; leakage current specified at 2500 µA after standard conditioning.
• Mechanical & Mounting Compact φ10×20 mm can with 5.0 mm lead spacing (±0.5 mm); radial lead configuration for through-hole mounting and simple board placement.
• Packaging & Availability Available in bulk (no terminal forming) and bag packing; product is in mass production and RoHS compliant.

Typical Applications

• General-purpose power filtering and decoupling — 1000 µF capacitance and low ESR help smooth supply rails and stabilize power for analog and digital circuits.
• High-frequency DC–DC converter outputs — 8.1 A ripple rating at 300 kHz and 10 mΩ ESR suit switch-mode regulator output filtering in compact designs.
• Bulk energy storage in compact radial designs — φ10×20 mm package and radial leads provide a space-efficient option for energy reservoirs on through-hole boards.

Unique Advantages

• Low conduction losses: 10 mΩ ESR at 100 kHz reduces I²R losses and improves efficiency in high-current circuits.
• High ripple handling across frequencies: Separate ripple ratings for 120 Hz and 300 kHz enable reliable performance in both linear and switching power stages.
• Wide operating temperature range: −55°C to 105°C supports deployment in varying thermal environments.
• Extended endurance at elevated temperature: 2000 hours at 105°C provides predictable aging characteristics for longer-term designs.
• Compact radial package: φ10×20 mm can with 5 mm lead spacing simplifies through-hole placement and mechanical retention on PCBs.
• RoHS compliant and production-ready: Mass production status and RoHS compliance support manufacturability and regulatory requirements.
