LGW2E821MELA50

The LGW2E821MELA50 is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LGW series, engineered for high ripple current operation at elevated temperatures. It delivers 820 µF capacitance at a 250 V rating and is specified for general‑purpose electronic applications that require sustained ripple endurance and long life at up to 105°C.

Designed as a radial, can‑style snap‑in package, this polarized capacitor combines high ripple capability with extended endurance — including rated ripple application for 3000 hours at 105°C — while meeting RoHS requirements.

Key Features

• Capacitance & Voltage: 820 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance, providing bulk energy storage for general‑purpose circuits.
• High Ripple Current & Endurance: Specified ripple current performance including 3 A at 120 Hz and 4.5 A at 50 kHz; qualified to withstand 3000 hours of rated ripple current at 105°C.
• Wide Operating Temperature: Rated for use from −40 °C to +105 °C, enabling operation across a broad thermal range for applications requiring elevated‑temperature capability.
• Snap‑in Radial Package: Snap‑in terminal, radial can package (L: 5 × D: 2.5 cm) for secure board mounting in applications that use snap‑in capacitors.
• Frequency Coefficients: Frequency correction factors for rated ripple current (200–250 V range) are provided (e.g., 0.81 at 50 Hz, 0.85 at 60 Hz, 1.00 at 120 Hz, up to 1.50 at 50 kHz), enabling designers to size ripple capability at different frequencies.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose electronic power circuits: Bulk capacitance and smoothing where sustained ripple endurance at elevated temperature is required.
• Power supply filtering: AC ripple filtering and energy storage in general‑purpose power modules operating up to 250 V.
• Industrial electronics: Applications needing polarized, high‑capacitance snap‑in capacitors with long ripple‑endurance life at 105 °C.

Unique Advantages

• Proven ripple endurance: Rated to withstand 3000 hours of applied rated ripple current at 105 °C, providing predictable life in high‑stress ripple environments.
• High ripple capability across frequency: Explicit ripple current ratings (3 A at 120 Hz; 4.5 A at 50 kHz) and frequency coefficients allow accurate thermal and ripple budgeting across common operating frequencies.
• High‑temperature operation: −40 °C to +105 °C operating range supports deployment in thermally demanding systems.
• RoHS compliant: Meets RoHS (2011/65/EU,(EU)2015/863) requirements for regulatory adherence in lead‑restricted product designs.
• Snap‑in radial can format: Robust snap‑in mounting and a compact L × D footprint (5 × 2.5 cm) for space‑efficient board integration in general‑purpose assemblies.
