LGU2A821MELA

The LGU2A821MELA is an aluminum electrolytic capacitor in a snap‑in terminal radial can designed for general‑purpose electronic applications. It provides 820 µF capacitance at a 100 V rating with a temperature range from −40°C to 105°C and a 3,000‑hour endurance at 105°C.

Key performance attributes include a low loss tangent (tan δ = 0.2 at 20°C, 120 Hz), defined leakage current, and strong ripple‑current capability across low and high frequencies—features that support reliable bulk capacitance and ripple handling in assemblies that use snap‑in mounting.

Key Features

• Electrolytic Core Aluminum electrolytic construction providing 820 µF of capacitance at a 100 V rating.
• Temperature & Endurance Rated for operation from −40°C to 105°C with 3,000 hours of endurance at 105°C under rated ripple and DC bias.
• Loss & Leakage tan δ = 0.2 (max) at 20°C, 120 Hz and specified leakage current of 850 µA for predictable dissipation and leakage behavior.
• Ripple Current Performance Low‑frequency ripple current 1.35 A at 120 Hz and high‑frequency ripple current 1.552 A at 50 kHz to support AC ripple handling across a range of frequencies.
• Mounting & Package Snap‑in terminal, radial can package (φ25 × 25 mm) for secure board installation and high‑current connections.
• RoHS Compliance Compliant with RoHS requirements for restricted substances.

Typical Applications

• General‑purpose electronic circuits — Provides bulk capacitance and ripple handling where a 100 V, 820 µF snap‑in capacitor is required.
• Power filtering and decoupling — Used in circuits that require sustained ripple current capability at both low and high frequencies.
• High‑temperature environments — Suitable for designs requiring operation up to 105°C with a specified 3,000‑hour endurance.

Unique Advantages

• High voltage and large capacitance in a compact can: 820 µF at 100 V offers substantial stored energy for equipment requiring elevated DC rail capacitance.
• Extended high‑temperature life: 3,000 hours endurance at 105°C ensures sustained performance under prolonged thermal stress.
• Wide operating temperature range: −40°C to 105°C supports deployment in environments with significant thermal variation.
• Defined ripple capability across frequencies: Rated ripple currents of 1.35 A (120 Hz) and 1.552 A (50 kHz) let designers quantify ripple handling for both mains‑frequency and higher‑frequency sources.
• Predictable electrical characteristics: Specified tan δ (0.2 at 20°C, 120 Hz) and 850 µA leakage current aid in thermal and leakage budgeting during design.
• Robust snap‑in mounting: Radial, snap‑in can package provides secure mechanical and electrical connection for board‑level power components.
