LGU1E822MELZ

The LGU1E822MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series designed for general‑purpose power applications. It provides 8.2 mF (8200 μF) capacitance at 25 V with a compact radial, snap‑in can package (φ22 × 35 mm).

Engineered for sustained operation up to 105°C, this part delivers rated ripple handling and long endurance—making it suitable for high‑reliability power filtering and bulk energy storage in volume production environments.

Key Features

• High Capacitance: 8.2 mF (8200 μF) nominal capacitance for bulk filtering and energy reserve in power rails.
• Rated Voltage: 25 V working voltage suitable for low‑voltage power systems and DC rails.
• Snap‑In Radial Can Package: φ22 × 35 mm snap‑in terminal construction for secure PCB mounting and automated assembly (tray packing).
• Wide Operating Temperature: Specified from −40°C to +105°C for use across a broad thermal range.
• Long Endurance: Endurance rating of 3000 hours at 105°C with DC bias plus rated ripple current applied, meeting LGU series endurance requirements.
• Ripple Current Capability: Low‑frequency ripple current 2.14 A at 120 Hz and high‑frequency ripple current 2.461 A at 50 kHz to support smoothing in switching and linear power stages.
• Leakage Current: Specified leakage current of 1350 μA (measured after 5 minutes at 20°C), enabling predictable standby and bias behavior.
• Capacitance Tolerance: ±20% at 120 Hz, 20°C for design margining and binning.
• RoHS Compliant: Meets RoHS directive requirements for restriction of hazardous substances.

Typical Applications

• General‑purpose power supplies: Bulk filtering and energy storage on DC rails where 25 V operation and high capacitance are required.
• Industrial control equipment: Smoothing of ripple and transient loads in power modules that operate across −40°C to +105°C.
• Consumer and commercial electronics: Bulk decoupling and power stabilization in high‑volume assemblies using snap‑in mounting and tray packing.

Unique Advantages

• Sustained high‑temperature endurance: 3000 hours at 105°C under rated ripple provides predictable lifetime performance in elevated ambient conditions.
• Designed for ripple‑intensive circuits: Specified ripple current values at both low (120 Hz) and high (50 kHz) frequencies allow designers to size capacitance for switching supplies and large‑signal loads.
• Compact snap‑in form factor: φ22 × 35 mm radial can with snap‑in terminals simplifies board retention and supports automated assembly and tray handling.
• Stable leakage and tolerance characteristics: Defined leakage current (1350 μA) and ±20% capacitance tolerance enable reliable design calculations and margining.
• RoHS compliance: Meets environmental requirements for regulatory compliance in many production environments.
