LGY2A122MELZ40

The LGY2A122MELZ40 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGY long‑life assurance series. It delivers 1.2 mF capacitance at a 100 V rating and is a polarized, radial can snap‑in package designed for reliable power handling in industrial applications.

Engineered for high‑temperature, long‑life use, this part is suited to industrial power supplies and ballast applications where sustained ripple handling and dependable performance at elevated temperature are required. The device is RoHS‑compliant and built to withstand prolonged ripple current exposure at 105°C.

Key Features

• Electrical Performance: 1.2 mF capacitance with ±20% tolerance and a 100 V rated voltage. Leakage current is specified as I ≤ 3√CV (μA) after 5 minutes at 20°C.
• Long‑Life Endurance: Designed to withstand 5000 hours of rated ripple current at 105°C, with endurance limits defined for capacitance change, tan δ, and leakage current per the series specification.
• High‑Temperature Operation: Rated for operation from –40°C to +105°C, enabling use in elevated‑temperature industrial environments.
• Ripple Current Capability: Rated ripple current of 1.6 A at 120 Hz and 1.84 A at 50 kHz; frequency coefficients apply (120 Hz coefficient = 1.00, 50 kHz or more = 1.15) to size ripple allowances across frequencies.
• Low Loss Characteristic: Maximum tan δ of 0.20 at the 100 V rating (measured at 120 Hz, 20°C), indicating controlled dissipation for power applications.
• Package & Mounting: Radial can, snap‑in terminal type for secure board mounting in high‑current power modules and assemblies.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies: Bulk filtering and energy storage where sustained ripple handling and high‑temperature endurance are required.
• Ballast Applications: Designed for ballast circuits that demand reliable performance under continuous ripple stress at elevated temperatures.
• General‑Purpose Industrial Electronics: Power filtering and smoothing in industrial controllers and equipment that operate across –40°C to 105°C.

Unique Advantages

• Long life under stress: 5000 hours endurance at 105°C under rated ripple current supports extended maintenance intervals and predictable replacement cycles.
• High voltage capability: 100 V rating provides headroom for higher‑voltage power rails without changing capacitor topology.
• Frequency‑aware ripple handling: Published ripple currents at 120 Hz and 50 kHz plus frequency coefficients allow designers to size capacitors accurately across operating frequencies.
• Predictable leakage behavior: Leakage current bounded by the I ≤ 3√CV formula after voltage application for straightforward power budget and standby current estimation.
• Snap‑in mounting: Robust terminal style for reliable mechanical retention and low‑impedance current paths in power assemblies.
• Regulatory compliance: RoHS conformity simplifies environmental compliance for assembled products.
