LGG2W271MELZ50

The LGG2W271MELZ50 from Nichicon is a snap‑in terminal, aluminum electrolytic capacitor in the LGG series optimized for space‑constrained, high‑voltage applications. It provides 270 µF capacitance at a 450 V rating, polarized construction, and snap‑in mounting for secure radial installation.

Designed for general‑purpose use, this part combines high‑voltage capability with a compact φ22 × 50 mm can, 105°C endurance characteristics and RoHS compliance, making it suitable for equipment designs that require reliable high‑voltage smoothing and energy storage in a smaller footprint.

Key Features

• Capacitance & Voltage: 270 µF rated at 450 V for high‑voltage energy storage and smoothing.
• High Temperature Endurance: Rated for 2000 hours at 105°C when subjected to DC bias plus rated ripple current, meeting LGG series endurance criteria.
• Ripple Current Handling: 1.05 A at 120 Hz (low frequency) and 1.502 A at 100 kHz (high frequency) to support significant ripple loads.
• Leakage & Loss: Specified leakage current of 1040 µA and tan δ (DF) of 0.2 max at 20°C, 120 Hz (450 V rating).
• Compact Snap‑In Package: Radial, can‑style snap‑in mounting (φ22 × 50 mm) for secure board attachment and reduced board area.
• Operating Temperature: −25°C to +105°C operating range as specified for the 400–450 V ratings in the LGG series.
• Regulatory Compliance: RoHS compliant per product information and LGG series documentation.

Typical Applications

• General‑purpose power filtering: Use for high‑voltage smoothing and bulk capacitance in general‑purpose equipment where a polarized, high‑voltage capacitor is required.
• Compact equipment designs: Suited for applications targeting equipment downsizing thanks to the LGG series’ smaller case sizing.
• High‑temperature environments: Applications that require 105°C endurance and a specified 2000‑hour lifetime at that temperature.

Unique Advantages

• High‑voltage capability: 450 V rating allows use in higher DC voltage circuits without series stacking.
• Robust ripple performance: Dual ripple current specifications (120 Hz and 100 kHz) quantify performance across low and high frequency stress conditions.
• Verified endurance: 2000 hours at 105°C under rated conditions provides a clear reliability expectation for thermal stress.
• Space‑saving package: φ22 × 50 mm snap‑in can offers a smaller case option within the LGG family for tighter layouts.
• Measured electrical characteristics: Specified tan δ and leakage current values provide predictable loss and leakage behavior for design validation.
• RoHS compliance: Conforms to RoHS directive requirements as noted for the LGG series.
