LGZ2W221MELC40

The LGZ2W221MELC40 is a snap‑in terminal aluminum electrolytic capacitor designed for long life operation at elevated temperatures. It delivers 220 µF capacitance at a 450 V rating in a radial, snap‑in can package tailored for general‑purpose power applications that require extended endurance.

Designed for equipment longevity, this part supports continuous operation up to 105 °C with a guaranteed endurance of 20,000 hours at that temperature, and is compliant with RoHS directives.

Key Features

• Electrical Performance: 220 µF rated capacitance with ±20% tolerance at 120 Hz and 20 °C; polarized design suitable for DC power applications.
• High Voltage Rating: 450 V rated voltage for high‑voltage smoothing and energy‑storage roles.
• Thermal and Lifetime Assurance: Rated for operation from −25 °C to 105 °C with a specified lifetime of 20,000 hours at 105 °C under rated ripple and DC bias.
• Ripple Current Capability: Rated ripple current of 1.00 A at 120 Hz (1,000 mArms); frequency coefficient allows up to 1.43 A at 50 kHz.
• Reliability Metrics: Leakage current specified by I ≤ 3√(C·V) μA after 5 minutes at 20 °C; tan δ ≤ 0.20 at 120 Hz, 20 °C. Endurance limits: capacitance change within ±25% and leakage ≤ initial value after endurance test.
• Package and Mounting: Radial, snap‑in can package (L: 4 × D: 3.5 cm) for secure board mounting and robust mechanical retention.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Filtering: Bulk smoothing and filtering in power conversion stages where 450 V rating and high operating temperature are required.
• Industrial Equipment: Energy storage and decoupling in equipment designed for prolonged operation at elevated temperatures, benefiting from the 20,000‑hour life assurance.
• High‑Voltage DC Link Circuits: Support for DC link and reservoir functions where high voltage rating and reliable ripple handling are necessary.

Unique Advantages

• Long Life at High Temperature: Rated for 20,000 hours at 105 °C, reducing replacement frequency and supporting longer equipment service intervals.
• High Voltage Handling: 450 V rating expands applicability to higher‑voltage power systems without series stacking.
• Robust Ripple Performance: 1.00 A rated ripple at 120 Hz with a 50 kHz capability up to 1.43 A (frequency coefficient), enabling reliable operation across a range of switching frequencies.
• Predictable Reliability Metrics: Clear endurance, shelf‑life and leakage specifications (including I ≤ 3√CV after 5 minutes) allow designers to model performance over time.
• Secure Board Mounting: Snap‑in terminal radial can simplifies mechanical retention for high‑vibration or high‑stress assemblies.
• Regulatory Compliance: RoHS conformity supports environmental restrictions in modern product lines.
