LGW2E271MELZ25

The LGW2E271MELZ25 is a snap‑in, radial can aluminum electrolytic capacitor designed for general‑purpose power applications. It provides 270 µF capacitance at a 250 V rating and is engineered for high ripple current performance at elevated temperature.

Built to operate up to 105°C and compliant with the RoHS Directive, this part targets applications that require reliable filtering and energy storage with long high‑temperature endurance.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance at a rated voltage of 250 V with capacitance tolerance ±20% (measured at 120 Hz, 20°C).
• High Ripple Current — Specified ripple current of 1.65 A at 120 Hz and 2.475 A at 50 kHz, supporting demanding AC ripple conditions.
• High‑Temperature Endurance — Endurance rating: withstanding 3,000 hours of rated DC bias plus rated ripple current at 105°C; capacitance change remains within ±20% after the test.
• Operating Temperature Range — –40°C to +105°C for the 200–250 V category, enabling use across wide thermal environments.
• Leakage Current Specification — Leakage current defined as I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20°C, facilitating predictable board‑level leakage behavior.
• Loss Tangent (tan δ) — Maximum tan δ of 0.15 at 120 Hz for the 200–400 V range (measurement at 20°C), supporting stable AC performance.
• Package & Mounting — Radial can with snap‑in terminals for secure PCB mounting and straightforward assembly.
• RoHS Compliance — Conforms to RoHS Directive (2011/65/EU, (EU)2015/863).
• Physical Size — Compact footprint with dimensions L: 2.5 × D: 2.2 cm for space‑conscious designs.

Typical Applications

• General‑purpose power filtering — Suited for power supply filtering and bulk energy storage tasks in systems that require 250 V, 270 µF capacitance with high ripple handling and 105°C endurance.

Unique Advantages

• Proven high‑ripple capability — Explicit ripple current ratings at 120 Hz and 50 kHz and a 3,000‑hour endurance at 105°C ensure predictable performance under continuous AC ripple stress.
• Wide temperature operation — –40°C to +105°C category temperature range for 200–250 V parts supports deployment in varied thermal environments.
• Predictable leakage behavior — Leakage current governed by the I ≤ 3√CV formula after rated voltage application provides quantifiable design parameters for power budgets.
• Compact snap‑in package — Radial can with snap‑in terminals offers reliable board retention and a small footprint for dense power assemblies.
• RoHS‑compliant supply chain — Conformance to RoHS directives simplifies regulatory considerations for design and manufacturing.
