LGW2D331MELZ25

The LGW2D331MELZ25 is an aluminum electrolytic capacitor from Nichicon's LGW series, featuring a snap‑in terminal radial can package. It provides 330 µF nominal capacitance at a 200 V rating and is designed for general‑purpose electronic applications that require sustained ripple handling and high‑temperature endurance.

Key value propositions include high ripple‑current capability with specified ripple ratings across frequency, 3000 hours endurance at 105°C under rated ripple conditions, and RoHS compliance for regulatory compatibility.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 200 V and ±20% tolerance at 120 Hz, 20°C.
• High Ripple Current — Rated ripple current 1.97 A at 120 Hz and 2.955 A at 50 kHz for the 330 µF / 200 V configuration; frequency coefficients for rated ripple current are provided in the LGW series datasheet.
• High‑Temperature Endurance — Specified to withstand 3000 hours with D.C. bias plus rated ripple current at 105°C; after this test the capacitor meets defined limits for capacitance change, dissipation factor (tan δ) and leakage current.
• Operating Temperature Range — Rated for operation from −40°C to +105°C for the 200–250 V range.
• Reliability Characteristics — Leakage current specification I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ max 0.15 for 200–400 V ratings; endurance and shelf‑life limits are defined in the datasheet.
• Package & Mounting — Radial, can type with snap‑in terminals for secure PCB mounting; physical size for this part is 22 × 25 mm (2.2 × 2.5 cm).
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose — High ripple environments Use where sustained ripple handling is required; the part’s rated ripple current and frequency coefficients are specified for design verification.
• General Purpose — Elevated temperature operation Applications that require long‑term operation at elevated temperature can leverage the LGW2D331MELZ25’s 3000‑hour endurance rating at 105°C under rated ripple current.
• General Purpose — Robust PCB mounting Snap‑in terminal construction provides a secure mounting option for designs that need reliable mechanical and electrical connections in a radial can package.

Unique Advantages

• High ripple resilience: Specified ripple current values (1.97 A at 120 Hz; 2.955 A at 50 kHz) and frequency coefficients allow designers to size capacitors confidently for ripple loading conditions.
• Proven high‑temperature endurance: Endurance specified for 3000 hours at 105°C under rated ripple ensures predictable lifetime behavior in thermally demanding systems.
• Clear reliability metrics: Datasheet limits for capacitance change, tan δ and leakage after endurance and shelf‑life tests support quantitative reliability assessments.
• Compact radial can with snap‑in terminals: 22 × 25 mm package offers a compact footprint with secure PCB retention suitable for through‑hole assembly.
• Regulatory readiness: RoHS compliance helps meet environmental directives without additional mitigation steps.
