LGM2W271MELA35

The LGM2W271MELA35 is an aluminum electrolytic capacitor in a snap‑in terminal, radial can package designed for high‑voltage bulk energy storage. It delivers 270 µF at 450 V in an ultra‑smaller‑sized case (one rank smaller than LGL), tailored for equipment downsizing where high voltage and compact footprint are required.

Built for general‑purpose power applications, the part supports operation from –25°C to +105°C and is RoHS compliant, providing a balance of performance and environmental conformance for industrial and power electronics designs.

Key Features

• Core Power — 270 µF capacitance rated at 450 V provides significant bulk energy storage for high‑voltage circuits.
• Package & Mounting — Snap‑in terminal, radial can construction simplifies installation and secures the component for PCB or chassis mounting; nominal size 25 × 35 mm (φD × L).
• Temperature & Endurance — Rated for –25°C to +105°C with an endurance specification of 2000 hours at 105°C under D.C. bias plus rated ripple current.
• Ripple Performance — Rated ripple current of 650 mArms at 105°C, 120 Hz (with frequency coefficients available); high‑frequency capability specified at 929.5 mA at 50 kHz.
• Leakage & Dielectric Loss — Leakage current meets I ≤ 3√CV (µA) after 5 minutes at 20°C; tangent of loss angle (tan δ) ≤ 0.20 at 120 Hz, 20°C.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies — Provides high‑voltage bulk capacitance for DC bus filtering and energy buffering in compact power supply designs.
• Power conversion modules — Suited for downsized inverter and converter assemblies where reduced case size and 450 V rating are required.
• UPS and energy storage interfaces — Supports high‑voltage smoothing and transient suppression in compact uninterruptible power systems and energy interface modules.
• Motor drive systems — Provides DC link capacitance for drives and controllers that demand reliable high‑voltage performance in a smaller footprint.

Unique Advantages

• Compact high‑voltage bulk capacitance: 270 µF at 450 V in an ultra‑smaller case enables equipment downsizing without sacrificing stored energy.
• Robust thermal endurance: Rated to 105°C with 2000 hours endurance under rated conditions, offering predictable life in elevated‑temperature environments.
• Strong ripple handling: 650 mArms rated ripple at 120 Hz and demonstrated high‑frequency capability (929.5 mA at 50 kHz) support demanding power applications.
• Predictable electrical characteristics: Leakage current bound by I ≤ 3√CV and tan δ ≤ 0.20 at 120 Hz help ensure consistent behavior across production lots.
• Secure snap‑in mounting: Snap‑in terminals provide mechanical retention and ease of assembly for radial can installations.
• RoHS compliance: Meets current RoHS requirements for environmentally conscious designs.
