LGR2E821MELB50

The LGR2E821MELB50 is an aluminum electrolytic capacitor from Nichicon’s LGR Long Life series featuring a snap‑in radial can and polarized terminals. It delivers 820 µF capacitance at 250 V DC with a ±20% tolerance and is designed for general-purpose applications.

Engineered for elevated-temperature operation, this part is rated for –40°C to +105°C and carries a long-life endurance rating of 10,000 hours at 105°C under D.C. bias plus rated ripple current. The device is RoHS compliant.

Key Features

• Capacitance & Voltage: 820 µF rated at 250 V DC with ±20% tolerance (specified at 120 Hz, 20°C).
• Long-Life Endurance: Designed to withstand 10,000 hours at 105°C with D.C. bias plus rated ripple current; after the endurance test, capacitance change is within ±25% and leakage current remains at or below initial specification.
• High Temperature Range: Operates from –40°C to +105°C, supporting high-temperature applications within its rated limits.
• Ripple Current Capability: Rated ripple current of 2 A at 120 Hz and 3 A at 50 kHz for effective handling of AC ripple across a range of frequencies.
• Leakage Current Specified: Leakage current meets the series criterion I ≤ 3√(C·V) µA after 5 minutes’ application of rated voltage at 20°C (series-level specification).
• Package & Mounting: Snap‑in radial can package for secure PCB mounting; physical size approximately L: 5 × D: 3 cm.
• Compliance: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power electronics — Bulk capacitance and energy support for circuits requiring a 250 V, 820 µF polarized capacitor with extended high-temperature life.
• Industrial and commercial equipment — Suitable where long endurance at elevated temperatures and reliable ripple handling are required.
• Electronic assemblies with snap‑in mounting — Radial snap‑in package enables secure mechanical and electrical installation in general-purpose designs.

Unique Advantages

• Extended high‑temperature life: 10,000‑hour endurance at 105°C provides predictable aging characteristics for long-term designs.
• Broad frequency ripple handling: Rated ripple current values at both 120 Hz and 50 kHz support performance across common operating frequencies.
• Defined leakage performance: Leakage current specified by the I ≤ 3√(C·V) relation gives a verifiable pass criterion after initial voltage application.
• Polarized, high-voltage capability: 250 V rating and polarized construction provide high-capacitance support where DC polarity is present.
• RoHS compliant: Meets applicable RoHS directives for restricted substances.
• Secure snap‑in mounting: Radial, snap‑in can simplifies board assembly for general-purpose equipment.
