LGX2E821MELC30

The LGX2E821MELC30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGX series. It delivers 820 µF capacitance at a 250 V rating in a snap‑in radial can package designed for power‑electronics applications.

Engineered for long life under elevated temperatures, this part withstands 5000 hours of rated ripple current at 105°C and is well suited for rectifier circuits in general inverters and switching power supplies. The device is RoHS compliant.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 250 V rated voltage; capacitance tolerance ±20% at 120 Hz, 20°C.
• Long‑life, High‑temperature Endurance — Endurance specification: meets required performance after DC bias plus rated ripple current applied for 5000 hours at 105°C.
• Operating Temperature Range — Specified for −25°C to +105°C operation, suitable for elevated‑temperature power circuits.
• Ripple Current Capability — Rated ripple current of 2.15 A at 120 Hz and 3.225 A at 50 kHz for handling AC ripple in power stages.
• Leakage Current Specification — Series leakage current follows I ≤ 3√(C·V) μA after 5 minutes at 20°C (C in μF, V in V), enabling predictable leakage behavior.
• Package & Mounting — Radial, can‑style snap‑in terminals for secure PCB mounting and reliable mechanical retention; printed marking in white on black sleeve.
• Electrical Stability — Series tan δ and low‑temperature impedance characteristics defined in the LGX datasheet to support design verification (tan δ max 0.15 for 200–400 V at 120 Hz, 20°C; Z(−25°C)/Z(+20°C) max 4 for 200–250 V).

Typical Applications

• General Inverters — Used on rectifier and smoothing stages where high DC voltage and robust ripple handling at elevated temperature are required.
• Switching Power Supplies — Bulk and output filtering for industrial and power conversion designs operating up to 250 V.
• Industrial Power Electronics — Energy storage and decoupling in motor drives and other industrial converters subject to sustained ripple and high ambient temperatures.

Unique Advantages

• Long‑term thermal reliability — Rated to endure 5000 hours at 105°C under rated ripple, reducing maintenance and replacement frequency in high‑temperature applications.
• High ripple handling across frequencies — Specified ripple current at both 120 Hz and 50 kHz supports designs exposed to low‑ and high‑frequency ripple components.
• Predictable leakage behavior — Leakage current specified by a clear formula (I ≤ 3√CV μA) enables accurate power‑loss and standby calculations.
• Serviceable snap‑in package — Radial snap‑in can simplifies PCB assembly and provides robust mechanical retention for power boards.
• RoHS‑compliant — Meets relevant RoHS directives for materials compliance.
