LGN2W121MELZ35

The LGN2W121MELZ35 is an aluminum electrolytic, snap-in terminal capacitor designed for general-purpose power applications. It combines a 450V voltage rating with 120 µF capacitance in a compact φ22 × 35 mm can, delivering high-voltage energy storage and filtering capability where robust ripple handling and long endurance at elevated temperature are required.

Engineered for continuous operation up to 105°C with a rated endurance of 3000 hours, this part addresses applications that demand sustained performance under DC bias and ripple stress while remaining RoHS compliant.

Key Features

• Electrolytic construction & mounting — Aluminum electrolytic capacitor with snap-in radial can package for secure board mounting and high current handling.
• Rated capacitance & voltage — 120 µF nominal capacitance with ±20% tolerance at a 450V rated voltage, suitable for high-voltage general-purpose circuits.
• Loss characteristic (tan δ) — tan δ ≤ 0.20 measured at 20°C and 120 Hz, providing a defined dissipation factor for design calculations.
• Ripple current capability — 720 mA at 120 Hz (low frequency) and 1.03 A at 100 kHz (high frequency) to support substantial AC superimposed currents during operation.
• Low leakage — Specified leakage current of 690 µA for stable performance after voltage application.
• High-temperature endurance — Rated for 3000 hours at 105°C under DC bias plus rated ripple current, demonstrating long-term reliability in elevated-temperature environments.
• Operating temperature range — −25°C to +105°C to accommodate a wide span of ambient conditions for general-purpose equipment.
• Compact package & packing — φ22 × 35 mm can size (L: 3.5 × D: 2.2 cm) in tray packing and available for mass production deployment.
• Environmental compliance — RoHS-compliant construction.

Typical Applications

• General-purpose power circuits — Energy storage and smoothing in circuits that require a 450V-rated electrolytic capacitor with robust ripple handling.
• High-voltage filtering — Bulk filtering and decoupling where 120 µF at 450V and defined tan δ are required for stable operation.
• Industrial power equipment — Applications needing long endurance at elevated temperature (3000 h at 105°C) while operating under DC bias and ripple stress.

Unique Advantages

• High-voltage capability: 450V rating enables use in higher-voltage general-purpose designs without changing capacitor family.
• Robust ripple handling: Dual-spec ripple ratings (720 mA at 120 Hz and 1.03 A at 100 kHz) support both low- and high-frequency ripple environments.
• Long endurance at temperature: 3000 hours at 105°C under rated conditions provides predictable lifetime for thermal-stressed designs.
• Compact snap-in package: φ22 × 35 mm snap-in can offers a space-efficient high-voltage solution with secure board retention.
• Controlled loss and leakage: Specified tan δ (≤0.20) and leakage current (690 µA) give measurable parameters for circuit design and reliability calculations.
• RoHS compliant: Meets environmental directive requirements for compliant manufacturing and procurement.
