RNE1C821MDN1

The RNE1C821MDN1 from Nichicon is a conductive polymer aluminum solid electrolytic capacitor in a radial lead can. It delivers 820 µF capacitance at 16 V with a compact φ10 × 12.5 mm case and 5.0 mm lead spacing for through-hole mounting.

Engineered for general-purpose power electronics, this part combines high capacitance, low ESR and strong ripple-handling capability to support power supply filtering, decoupling and energy-holding tasks in industrial and commercial designs.

Key Features

• Conductive polymer solid electrolyte — Solid polymer construction for stable electrical characteristics and high-frequency performance.
• Capacitance and rating — 820 µF nominal capacitance at a rated voltage of 16 V with tolerance of −20% to +20%.
• Low ESR and dielectric loss — ESR of 11 mΩ measured at 20°C/100 kHz and tanδ (DF) of 0.08 at 20°C/120 Hz, reducing power loss in high-frequency applications.
• High ripple-current capability — Rated ripple currents of 560 mA at 120 Hz and 5.6 A at 300 kHz for effective heat and ripple management across frequency ranges.
• Thermal and lifetime performance — Operating temperature range −55°C to +105°C with a rated endurance of 2000 hours at 105°C.
• Radial lead package — φ10 × 12.5 mm can with 5.0 mm lead spacing (±0.5 mm) for through-hole assembly; available in bulk (no terminal forming) or bag packing.
• Regulatory status — RoHS compliant; part is in mass production.

Typical Applications

• Power supply filtering: Use as bulk smoothing and output filtering where 820 µF capacitance and low ESR (11 mΩ) reduce ripple and improve voltage stability.
• DC‑DC converter output capacitors: Suitable for converter outputs that require high ripple-current handling (5.6 A at 300 kHz) and compact radial mounting.
• General-purpose industrial electronics: Applied in control boards and sensor systems that need wide operating temperature range (−55°C to 105°C) and reliable endurance at elevated temperature.
• Consumer power rails: For devices requiring high capacitance in a small through-hole package, providing decoupling and transient energy support.

Unique Advantages

• High ripple tolerance: 5.6 A rating at 300 kHz minimizes internal heating under high-frequency ripple conditions, improving reliability in switching environments.
• Low loss at high frequency: 11 mΩ ESR at 100 kHz and tanδ 0.08 at 120 Hz reduce power dissipation and support efficient high-frequency performance.
• Compact through-hole form: φ10 × 12.5 mm can with 5.0 mm lead spacing offers a space-efficient radial option for legacy and mixed-technology PCBs.
• Wide temperature endurance: −55°C to 105°C operating range and 2000-hour life at 105°C provide predictable aging characteristics in thermal stress conditions.
• Supply readiness: RoHS compliant and in mass production with bulk and bag packing options to support prototyping through volume assemblies.
