LGR2D821MELA50

The LGR2D821MELA50 is an aluminum electrolytic capacitor in a snap‑in terminal radial can designed for long‑life, high‑temperature use. It delivers 820 µF at a 200 V rating and is intended for general‑purpose power applications where sustained ripple endurance and elevated operating temperature capability are required.

Built as part of Nichicon’s LGR long‑life series, this snap‑in capacitor is specified for operation from −40 °C to +105 °C and is rated to withstand 10,000 hours of rated ripple current at 105 °C. The device is RoHS compliant.

Key Features

• Core technology Aluminum electrolytic construction with polarized terminals, optimized for bulk energy storage in general‑purpose power circuits.
• Capacitance and rated voltage 820 µF nominal capacitance with a 200 V rated voltage and a tolerance range of −20% to +20%.
• Long‑life, high‑temperature endurance Specified for 10,000 hours of endurance at 105 °C under D.C. bias plus rated ripple current (series endurance requirement).
• Ripple current capability Rated ripple current of 2 A at 120 Hz and 3 A at 50 kHz for handling both low‑frequency and higher‑frequency ripple components.
• Electrical characteristics Leakage current conforms to the series limit I ≤ 3√(C·V) µA after 5 minutes at 20 °C; tan δ maximum for 200–400 V series types is 0.15 (series specification).
• Low‑temperature stability For 200 V types in the series, impedance ratios are specified (Z(−25 °C)/Z(+20 °C) up to 3 and Z(−40 °C)/Z(+20 °C) up to 12), reflecting defined low‑temperature behavior.
• Mounting and package Snap‑in terminal radial can package for board insertion; nominal physical size L: 5 cm × D: 2.5 cm with snap‑in mounting for secure PCB retention.
• Environmental compliance Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Supplies Bulk smoothing and energy storage for general‑purpose power conversion and filtering.
• Industrial Electronics Long‑life power filtering in industrial control and instrumentation equipment operating up to 105 °C.
• Stationary Power Modules Decoupling and bulk capacitance in non‑automotive stationary or rack‑mounted power systems requiring extended ripple endurance.

Unique Advantages

• Long‑life assurance: Specified 10,000 hours of rated ripple endurance at 105 °C, providing predictable lifecycle behavior under elevated temperature and ripple stress.
• High capacitance at 200 V: 820 µF nominal gives substantial bulk energy storage for smoothing and decoupling within a compact radial can footprint.
• Defined ripple performance across frequency: Explicit ripple current ratings at 120 Hz and 50 kHz support mixed low‑ and high‑frequency ripple environments.
• Documented electrical limits: Leakage current and tan δ limits are specified by the series datasheet, enabling reliable design margin calculations.
• Robust temperature range: Rated for operation from −40 °C up to +105 °C (for 200 V types), suitable for elevated ambient applications.
• RoHS compliant: Meets applicable RoHS directives for environmental regulatory requirements.
