LGL2W821MELC50

The LGL2W821MELC50 from Nichicon is an ultra-smaller-sized, snap-in terminal aluminum electrolytic capacitor in the LGL series. It delivers 820 µF at a 450 V rating in a radial, can-style snap-in package engineered for general-purpose applications.

Designed for elevated operating temperatures, this part supports a –25 °C to +105 °C operating range and an endurance of 2000 hours at 105 °C under D.C. bias plus rated ripple current, making it suitable where high-voltage capacitance and thermal robustness are required.

Key Features

• Electrical capacity and voltage — 820 µF rated capacitance with a 450 V rated voltage, providing high stored energy in a compact snap-in package.
• High-temperature endurance — Rated for operation from –25 °C to +105 °C with an endurance specification of 2000 hours at 105 °C under D.C. bias plus rated ripple current.
• Snap-in radial can package — Radial, can-style snap-in mounting for secure PCB installation and straightforward assembly.
• Ripple current capability — Rated ripple currents include 1.93 A at 120 Hz and 2.76 A at 50 kHz; frequency coefficients are provided for scaling ripple with frequency across the 400–450 V range.
• Reliability and aging — Endurance and shelf-life criteria: capacitance change within ±20%, tan δ up to 200% of initial specified value, and leakage current at or below initial specified limits after endurance and shelf-life tests.
• Electrical characteristics — Polarized capacitor with capacitance tolerance of –20% to +20% and leakage current specified as I ≤ 3√(μA) after 5 minutes at rated voltage (20 °C); tan δ maximum of 0.20 at 450 V (120 Hz, 20 °C).
• Compact dimensions — Physical size L: 5 × D: 3.5 cm and a seated height specification of 1.969 inch, enabling space-efficient implementation where a high-voltage capacitor is needed.

Typical Applications

• General-purpose systems — Intended for general-purpose applications that require a 450 V, 820 µF snap-in aluminum electrolytic capacitor.
• High-temperature environments — Suitable where operation at elevated temperatures is required, supported by an operating range to 105 °C and a 2000-hour endurance at that temperature.
• PCB-mounted power modules — Radial, snap-in can package for secure board-mounted use in power assemblies and modules.
• AC ripple management — Handles rated ripple currents (e.g., 1.93 A at 120 Hz, 2.76 A at 50 kHz) for applications requiring ripple smoothing under D.C. bias.

Unique Advantages

• High-voltage energy density: 820 µF at 450 V provides significant capacitance for high-voltage circuits in a compact form factor.
• Thermal robustness: Rated for continuous operation to 105 °C with 2000 hours of endurance under D.C. bias plus rated ripple current, helping maintain performance in elevated temperature conditions.
• Snap-in mounting convenience: Radial snap-in termination simplifies mechanical retention on the PCB while providing a reliable electrical connection.
• Measured ripple capability: Documented ripple current values at common test frequencies and frequency coefficients allow predictable ripple handling across frequency ranges.
• Documented reliability criteria: Endurance and shelf-life specifications (capacitance, tan δ, leakage current) provide clear, testable limits for long-term performance assessment.
