LGX2W101MELA25

The LGX2W101MELA25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGX long‑life assurance series. It delivers 100 µF at 450 V in a compact radial can with snap‑in mounting, designed for power‑electronic use where elevated temperature endurance and reliable filtering are required.

Engineered for rectifier circuits in general inverters and switching power supplies, this capacitor offers a 105 °C rated temperature range with a 5,000‑hour endurance under rated ripple current, plus RoHS compliance for regulated environments.

Key Features

• Electrical rating — 100 µF nominal capacitance at 450 VDC with a tolerance of ±20% (120 Hz, 20 °C).
• High‑temperature endurance — Rated to operate from −25 °C to +105 °C and guaranteed for 5,000 hours when subjected to D.C. bias plus rated ripple current at 105 °C.
• Ripple current capability — Specified rated ripple current of 700 mA at 120 Hz and 1.001 A at 50 kHz for effective smoothing in power applications.
• Leakage current specification — Leakage current after 5 minutes at 20 °C follows I ≤ 3√CV (µA), enabling predictable design of power loss and bias conditions.
• Loss and stability parameters — tan δ max of 0.20 at 450 V (measurement: 120 Hz, 20 °C); low‑temperature impedance ratio Z(−25 °C)/Z(+20 °C) up to 8 for rated voltages 400–500 V.
• Compact, snap‑in package — Radial can with snap‑in terminals and a compact footprint: L 25 mm × D 25 mm, max seated height 25 mm, marked with white lettering on a black sleeve for easy identification.
• Endurance and shelf life — After the specified endurance test, capacitance remains within ±20% and tan δ and leakage remain within specified recovery limits; shelf life treatment also defined (105 °C for 1000 hours then voltage treatment).
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Inverter rectifier circuits — Provides smoothing and energy storage in the rectifier stages of general inverters where elevated temperature endurance is required.
• Switching power supplies — Used for bulk filtering and ripple suppression in switching power supplies operating at high voltage and elevated ambient temperatures.
• General purpose power electronics — Suitable for industrial and commercial power modules requiring a compact snap‑in capacitor with defined high‑temperature lifetime.

Unique Advantages

• Long‑life assurance at elevated temperature — 5,000 hours rated endurance at 105 °C under rated ripple current supports reliable operation in hot operating environments.
• Predictable ripple handling — Specified ripple current values at both 120 Hz and 50 kHz help designers size thermal and ripple stress margins accurately.
• Compact snap‑in form factor — Radial can with snap‑in terminals and a 25 mm × 25 mm footprint saves board space while simplifying assembly for vertical mounting.
• Defined electrical stability — Clear limits for capacitance change, tan δ, and leakage after endurance and shelf tests enable deterministic reliability modeling.
• RoHS compliant — Meets current RoHS requirements for use in products targeting regulated markets.
