LGL2W221MELZ40

The LGL2W221MELZ40 is a 220 µF, 450 V aluminum electrolytic capacitor in a snap-in terminal radial can. Engineered for general-purpose high-voltage designs, it combines a 22 mm diameter × 40 mm length ultra-smaller-sized package with a 105°C rated temperature capability.

This part delivers a balance of high-voltage capability, ripple handling and endurance—featuring ±20% capacitance tolerance, low-frequency and high-frequency ripple specifications, a measured leakage current, and a 2000-hour endurance rating at 105°C—making it suitable for demanding power-conditioning roles in industrial and electronic equipment.

Key Features

• Electrical Performance — Rated capacitance 220 µF with ±20% tolerance at 120 Hz, 20°C; rated voltage 450 V; tangent of loss angle (tan δ) up to 0.20 at 20°C, 120 Hz for the 450 V rating.
• Ripple and Leakage — Low-frequency ripple current 850 mA at 120 Hz and high-frequency ripple current 1.216 A at 100 kHz; specified leakage current at 940 µA.
• Thermal and Endurance — Operating temperature range −25°C to +105°C with 2000 hours endurance at 105°C when subjected to rated DC bias plus rated ripple current.
• Package and Mounting — Snap-in terminal type in a radial can package for robust PCB mounting; supplied in tray packing for production handling.
• Compact Footprint — Ultra-smaller-sized 22 mm diameter and 40 mm length (L: 4.0 cm × D: 2.2 cm) suitable where board space and high-voltage capability must be balanced.
• Polarized — Polarized aluminum electrolytic design for standard DC power applications.

Typical Applications

• High‑voltage power supplies — Bulk smoothing and ripple filtering in circuits that require a 450 V rated capacitor and measurable ripple handling at both low and high frequencies.
• Industrial power conversion — Energy storage and decoupling in converters and inverters where operation up to 105°C and multi‑hour endurance (2000 h) are required.
• General-purpose high-voltage circuits — Use in electronic assemblies that demand a compact, snap‑in aluminum electrolytic capacitor with defined leakage and loss-angle characteristics.

Unique Advantages

• High voltage capability: 450 V rating supports designs that require elevated DC voltage handling without upsizing the capacitor footprint.
• Dual-frequency ripple handling: Specified ripple performance at 120 Hz (850 mA) and at 100 kHz (1.216 A) provides verifiable behavior across common power‑supply frequencies.
• Compact, production-friendly package: 22 × 40 mm snap-in radial can with tray packing simplifies PCB layout and streamlines assembly for mass production.
• Elevated temperature endurance: 2000 hours at 105°C under rated bias demonstrates sustained performance in hot operating environments.
• Defined leakage and loss characteristics: Leakage current of 940 µA and tan δ ≤ 0.20 (450 V, 120 Hz, 20°C) enable predictable design margins for power conditioning.
