LGR2W820MELA35

The LGR2W820MELA35 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGR Long Life series. It delivers 82 µF at a 450 V rating with a polarized radial can package designed for secure snap‑in mounting.

Engineered for long‑life performance, this part is rated for operation from −25 °C to 105 °C and is specified to withstand 10,000 hours of DC bias plus rated ripple current at 105 °C. It is RoHS compliant and intended for general‑purpose use where high voltage, long endurance and robust ripple handling are required.

Key Features

• Capacitance & Voltage — 82 µF capacitance with a 450 V rated voltage for high‑voltage bulk energy storage and filtering.
• Long Life Endurance — Specified endurance of 10,000 hours at 105 °C under DC bias plus rated ripple current; after endurance test capacitance change remains within ±25% and leakage current remains at or below initial specified value.
• Temperature Range — Rated for −25 °C to +105 °C (for 400/450 V range), supporting prolonged elevated‑temperature operation.
• Ripple Current Capability — Rated ripple current of 560 mA at 120 Hz and 800.8 mA at 50 kHz, with published frequency coefficients for 400/450 V that allow adjustment of ripple rating across frequency.
• Electrical Reliability — Leakage current specified by I ≤ 3√CV (µA) after 5 minutes at 20 °C; tan δ maximum 0.20 at 450 V for dielectric quality control.
• Package & Mounting — Radial, snap‑in can package for secure chassis or PCB mounting; polarized terminal configuration for proper polarity orientation.
• Physical & Marking — Compact footprint with dimensions approximately 3.5 × 2.5 cm (L × D); marked with white lettering on a black sleeve for clear identification.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑voltage power supplies — Bulk smoothing and filtering where a 450 V rated capacitor and long‑life endurance are required.
• Power conversion — DC‑link and ripple buffering in industrial converters that operate at elevated temperatures.
• Industrial equipment — General‑purpose energy storage and filtering in systems exposed to sustained thermal stress up to 105 °C.

Unique Advantages

• Long high‑temperature life: 10,000 hours endurance at 105 °C under rated conditions provides predictable aging and maintenance intervals for thermal‑stress applications.
• High voltage capability: 450 V rating enables use in higher‑voltage power circuits without series stacking.
• Frequency‑aware ripple handling: Provided ripple current ratings at 120 Hz and 50 kHz plus frequency coefficients for 400/450 V allow designers to size for real operating frequencies.
• Measured leakage and dissipation limits: Leakage current bound by I ≤ 3√CV after 5 minutes at 20 °C and tan δ specified for 450 V give clear pass/fail criteria during qualification.
• RoHS compliance: Meets RoHS (2011/65/EU, (EU)2015/863) for environmental and regulatory alignment.
