LGW2E821MELB35

The LGW2E821MELB35 is an aluminum electrolytic, snap‑in terminal capacitor designed for general-purpose power applications that demand high ripple current handling and elevated temperature performance. Built to operate up to 105°C and compliant with RoHS, this radial can provides 820 µF at 250 V with snap‑in mounting for secure panel or chassis installation.

Key Features

• Electrical Performance — 820 µF nominal capacitance at a rated voltage of 250 V with ±20% tolerance, polarized design for DC energy storage and smoothing.
• High Ripple Current — Rated ripple current of 3 A at 120 Hz (low frequency) and 4.5 A at 50 kHz (high frequency), supporting applications with substantial AC ripple stress.
• Thermal and Reliability — Specified operating temperature range of −40 °C to +105 °C and endurance tested for 3000 hours at 105 °C with DC bias plus rated ripple current.
• Leakage and Loss Characteristics — Leakage current specified as I ≤ 3√CV (µA) after 5 minutes at 20 °C; tangent of loss angle (tan δ) max. 0.15 for 200–400 V at 120 Hz, 20 °C.
• Package & Mounting — Radial, can-style snap‑in package for robust board/chassis retention; dimensions approximately L: 3.5 cm × D: 3.0 cm with a seated height specification included in product data.
• Identification & Compliance — Marked with white lettering on a black sleeve; compliant with the RoHS directive.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple reduction in general‑purpose AC/DC and DC/DC power supplies where high ripple current and 105 °C operation are required.
• Industrial Power Modules — Input or output filtering and energy buffering in industrial converters and motor drive modules that operate at elevated temperatures.
• Energy Storage for Control Electronics — Local decoupling and bulk storage for control and power electronics that need reliable capacitance under continuous ripple stress.

Unique Advantages

• High ripple endurance: Rated ripple current values and a 3000‑hour endurance at 105 °C enable sustained operation under continuous AC ripple loading.
• Wide operating temperature range: −40 °C to +105 °C supports deployment in environments with substantial temperature variation.
• Robust mounting: Snap‑in radial can provides secure mechanical retention for chassis or PCB installations, simplifying assembly.
• Measurable electrical stability: Leakage and tan δ limits (I ≤ 3√CV, tan δ max. 0.15 at 120 Hz for 200–400 V) give clear, testable electrical characteristics for design validation.
• RoHS compliant: Meets RoHS requirements for restricted substances, supporting regulatory and manufacturing compliance.
