RNL1E821MDSBSQ

The RNL1E821MDSBSQ from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in the RNL series, designed for general-purpose power applications. It delivers 820 µF capacitance at a 25 V rating in a radial lead can (φ10×16L) with 5.0 mm lead spacing.

Engineered for low ESR and high ripple capability, this component targets designs that need stable bulk capacitance and high-frequency ripple handling across a broad temperature range of −55°C to 105°C, with a rated lifetime of 5000 hours at 105°C.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 25 V and a tolerance of −20% to +20%.
• Conductive Polymer Electrolyte — Solid conductive polymer construction for the RNL series, providing high capacitance in a compact aluminum can form.
• Low ESR — Equivalent series resistance of 10 mΩ measured at 20°C/100 kHz, supporting efficient high-frequency performance.
• High Ripple Current Handling — Rated low-frequency ripple current of 580 mA at 120 Hz and high-frequency ripple current of 5.8 A at 300 kHz for demanding power applications.
• Loss Angle (tan δ) — tanδ of 0.12 measured at 20°C, 120 Hz, suitable for predictable AC behavior in filtering roles.
• Leakage Current — Specified leakage current of 2050 µA (measured at 20°C after 2 minutes), enabling predictable bias behavior.
• Reliability & Lifetime — Endurance rating of 5000 hours at 105°C under rated voltage conditions, with defined limits for capacitance change, tanδ and ESR.
• Mechanical & Packaging — Radial lead mounting, polarized, case size φ10×16L, lead spacing 5.0 mm (±0.5 mm). Available in bulk (no terminal forming) or bag packing. RoHS compliant.

Typical Applications

• General-purpose power circuits — Specified as "General Purpose" in the product data; suited where a combination of large capacitance and low ESR is required.
• High-frequency ripple suppression — High-frequency ripple current rating (5.8 A at 300 kHz) and low ESR support applications that require effective HF decoupling within the stated limits.
• Bulk energy storage — 820 µF capacitance and 25 V rating provide localized bulk capacitance for power rails in general-purpose designs.

Unique Advantages

• High capacitance in a compact can: 820 µF in a φ10×16 mm package offers substantial bulk storage while conserving board area.
• Low ESR at high frequency: 10 mΩ ESR at 100 kHz enables reduced loss and improved thermal performance under AC ripple conditions.
• Strong ripple capability: Rated ripple currents of 580 mA (120 Hz) and 5.8 A (300 kHz) allow the part to handle both low- and high-frequency ripple within specified limits.
• Wide operating temperature range: −55°C to 105°C supports deployment across a broad range of ambient conditions.
• Long endurance at elevated temperature: 5000 hours life at 105°C gives designers a defined reliability metric for thermal stress planning.
• RoHS compliant packaging options: Supplied in bulk or bag packing with radial lead form, simplifying procurement and assembly choices.
