LGZ2W221MELB50

The LGZ2W221MELB50 is an aluminum electrolytic capacitor in a snap‑in terminal radial can designed for long life at elevated temperatures. It delivers 220 µF capacitance with a 450 V rated voltage and is specified for general purpose applications.

Key value propositions include extended endurance—20,000 hours at 105°C—robust ripple handling (1.00 A at 120 Hz, higher at elevated frequencies), low leakage, and a compact φ30 × 50 mm package suitable for tray packing and snap‑in board mounting.

Key Features

• Electrical characteristics — 220 µF nominal capacitance with ±20% tolerance and a 450 V rated voltage for high‑voltage general purpose designs.
• Leakage and loss — Specified leakage current of approximately 940 µA (0.94 mA) and a tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20°C.
• Ripple current capability — Rated ripple current of 1000 mArms at 105°C, 120 Hz; frequency coefficient table yields up to 1.43× at 50 kHz (≈1.43 A).
• Long‑life endurance — Endurance rating of 20,000 hours at 105°C with post‑test limits: capacitance change within ±25%, tan δ ≤ 250% of initial specified value, and leakage current ≤ initial specified value.
• Temperature performance — Category temperature range from −25°C to +105°C, with maximum impedance ratio Z(−25°C)/Z(+20°C) of 8 at 450 V (measured at 120 Hz).
• Package and mounting — Radial, snap‑in can (φ30 × 50 mm) designed for tray packing and secure board retention; polarized construction.
• RoHS compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose — Specified as a general‑purpose aluminum electrolytic capacitor for designs that require a 450 V rating and long operational life.
• High‑temperature environments — Suitable for applications that require continuous operation up to 105°C with defined 20,000 hour endurance characteristics.
• High ripple current circuits — Applicable where rated ripple current capability (1.00 A at 120 Hz, higher at elevated frequencies) is required for reliable operation.

Unique Advantages

• Extended operational life: 20,000 hours at 105°C supports longer maintenance intervals and predictable end‑of‑life behavior.
• High voltage capability: 450 V rating enables use in higher‑voltage general purpose designs without additional derating.
• Strong ripple handling: 1000 mArms at 120 Hz and a frequency coefficient up to 1.43 at 50 kHz provide headroom for demanding ripple environments.
• Compact snap‑in form factor: φ30 × 50 mm radial can with snap‑in terminals simplifies board retention for through‑hole assemblies.
• Measured stability across temperature: Specified impedance and tan δ limits support predictable performance from −25°C to +105°C.
• Regulatory compliance: RoHS conformity supports deployment in regions requiring restricted substances compliance.
