LGW2D471MELZ30

The LGW2D471MELZ30 is an aluminum electrolytic, snap‑in terminal capacitor designed for general‑purpose applications that require high capacitance at elevated voltage. It delivers 470 µF of capacitance at a 200 V rating in a compact 22 × 30 mm can, and is optimized for sustained ripple current performance at high operating temperatures.

Key value propositions include high ripple current capability, extended endurance under rated ripple at 105°C, and RoHS compliance—attributes suited to designs where reliable DC bus smoothing or energy buffering under thermal stress is required.

Key Features

• Rated capacitance and voltage: 470 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance, specified at 120 Hz, 20°C.
• Snap‑in radial can package: 22 × 30 mm body size in a radial, snap‑in can for secure board mounting and mechanical retention.
• High ripple current capability: Rated ripple current of 2.17 A at 120 Hz and 3.255 A at 50 kHz for robust AC stress handling.
• High‑temperature endurance: Endurance specified as 3000 hours when rated ripple current and DC bias are applied at 105°C; capacitors meet defined limits for capacitance change, tan δ and leakage after this test.
• Operating temperature range: −40°C to +105°C operating range for the 200 V class.
• Leakage current specification: Typical leakage defined by I ≤ 3√(C·V) (μA) after 5 minutes at 20°C; part listing shows a leakage characteristic of approximately 0.91 mA for this size and rating.
• Polarized design: Polarized electrolytic intended for DC applications where correct polarity is observed.
• RoHS compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Frequency coefficient for ripple: Frequency coefficient for rated ripple current rises with frequency (for 200–250 V range, up to 1.50 at ≥50 kHz), enabling higher allowable ripple at higher frequencies per the datasheet curve.

Typical Applications

• General‑purpose power systems: Bulk energy storage and DC bus smoothing where 200 V, 470 µF capacitance and high ripple endurance are required.
• Industrial electronics: Applications that operate at elevated temperatures and require long ripple endurance (3000 h at 105°C) under rated ripple and DC bias.
• High‑frequency power applications: Circuits that impose significant high‑frequency ripple benefit from the part’s increased rated ripple allowance at higher frequencies.

Unique Advantages

• Proven ripple endurance: Specified to withstand 3000 hours of rated ripple current at 105°C, helping ensure long‑term stability in thermally demanding applications.
• High capacitance in compact 22 × 30 mm can: 470 µF at 200 V in a small radial footprint, enabling space‑efficient board designs.
• Elevated ripple handling across frequencies: Ripple current ratings and frequency coefficients allow designers to size capacitors with confidence for both low‑ and high‑frequency ripple conditions.
• Snap‑in mounting for robust retention: Snap‑in terminals provide secure mechanical and electrical connection in PCB assemblies.
• Regulatory compliance: RoHS compliance supports environmentally restricted designs without additional material qualification.
