LGUW6271MELB

The LGUW6271MELB is a snap‑in terminal aluminum electrolytic capacitor rated at 420 V and 270 µF. It is a radial, can‑style, polar capacitor designed for general‑purpose power applications that require high voltage handling and sustained performance at elevated temperatures.

Key value propositions include a 105°C endurance rating with 3000 h life, robust ripple‑current capability across low and high frequencies, and RoHS compliance—making the part suitable for production designs requiring long‑term thermal/ripple endurance and straightforward board mounting.

Key Features

• Electrical ratings — 270 µF capacitance at a rated voltage of 420 V with ±20% tolerance.
• Loss and leakage — tanδ 0.15 (max) measured at 20°C and 120 Hz; specified leakage current 1010 µA.
• Ripple current performance — 1220 mA at 120 Hz (low frequency) and 1744.6 mA at 50 kHz (high frequency), supporting sustained AC ripple loading.
• High‑temperature endurance — Rated for 3000 hours at 105°C with specified endurance limits for capacitance, tanδ and leakage after test.
• Operating range — Specified operating temperature range from −25°C to +105°C.
• Mechanical and mounting — Snap‑in radial can package (φ30 × 40 mm), tray packing for production handling and easy PCB insertion.
• Compliance — RoHS compliant.

Typical Applications

• General‑purpose power systems — For circuits requiring 420 V voltage rating and 270 µF capacitance in a snap‑in radial package.
• DC bus and power filtering — Provides bulk capacitance and ripple current handling at 120 Hz and higher frequencies up to 50 kHz.
• Industrial and commercial equipment — Useful where elevated temperature endurance (3000 h at 105°C) and RoHS compliance are required.

Unique Advantages

• High voltage capability: 420 V rating enables use in higher‑voltage DC applications without series stacking.
• Long endurance at 105°C: 3000‑hour rated life supports designs that operate at elevated temperatures for extended periods.
• Broad ripple‑current handling: Specified ripple current at both 120 Hz and 50 kHz allows designers to size capacitors confidently for mixed‑frequency loads.
• Snap‑in radial packaging: φ30×40 mm can with snap‑in terminals for secure board mounting and efficient assembly using tray packing.
• Measured performance parameters: Specified tanδ and leakage current values provide clear electrical limits for design validation.
• Production readiness: Indicated mass production status and tray packing support volume assembly and procurement planning.
