LGW2G271MELZ50

The LGW2G271MELZ50 is an aluminum electrolytic capacitor in a snap‑in terminal radial can package designed for general‑purpose electronic applications. It provides 270 µF nominal capacitance at a 400 V rating with polarized construction and is optimized for high ripple current performance.

Key value propositions include high ripple current capability with validated endurance at elevated temperature, a wide operating temperature range to 105 °C, and RoHS compliance for regulated material use.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance at a 400 V rated voltage with ±20% tolerance.
• High Ripple Current Performance — Specified ripple current examples: 1.68 A at 120 Hz and 2.402 A at 50 kHz. The LGW series supports frequency-dependent ripple current scaling for the 400–450 V group.
• 105 °C Endurance — Capable of withstanding 3000 hours of rated ripple current at 105 °C; endurance criteria include capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current not exceeding initial specified value.
• Operating Temperature Range — Specified for −25 °C to +105 °C operation.
• Package & Mounting — Snap‑in terminal type in a radial can package, designed for secure snap‑in board mounting; size dimensions: L: 5 × D: 2.2 cm.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power electronics — For circuits requiring a 400 V polarized capacitor with high ripple current capability and extended high‑temperature endurance.
• Industrial equipment — Applicable where sustained ripple handling at elevated temperature and RoHS compliance are required.
• Commercial power supplies — Suited to designs that need bulk capacitance at 400 V with proven 3000‑hour ripple endurance at 105 °C.

Unique Advantages

• Validated high‑temperature endurance — 3000 hours at 105 °C under rated ripple current provides measurable reliability for heat‑stressed designs.
• Frequency‑aware ripple capability — Specified ripple current values at 120 Hz and 50 kHz, with series frequency coefficients for the 400–450 V group, help predict performance across operating frequencies.
• Robust mounting — Snap‑in radial can construction provides a secure, serviceable board attachment suited to moderate‑power assemblies.
• Regulatory readiness — RoHS compliance supports restricted‑materials requirements in assemblies.
• Clear electrical specification — Polarized 270 µF at 400 V and defined tolerance simplify BOM selection and circuit calculations.
