LGU2A122MELZ

The LGU2A122MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, optimized for general‑purpose power applications. It provides 1,200 µF capacitance at a 100 V rating with a compact φ22 × 40 mm can and tray packing for production readiness.

Designed for sustained operation, this capacitor is specified for an operating temperature range of −40°C to 105°C and a 3,000‑hour endurance at 105°C, addressing designs that require stable ripple handling and long life under elevated temperature conditions.

Key Features

• Capacitance & Voltage — 1.2 mF (1,200 µF) rated at 100 V with ±20% tolerance for bulk energy storage and smoothing in power circuits.
• Snap‑in Radial Package — Snap‑in terminal, radial can (φ22 × 40 mm) packaged in trays for PCB assembly and production handling.
• High Temperature Endurance — Rated for 3,000 hours at 105°C; the LGU series specifies endurance after DC bias plus rated ripple current is applied at 105°C.
• Ripple Current Performance — 1,740 mA at 120 Hz (low frequency) and 2,001 mA at 50 kHz (high frequency), supporting applications with significant AC ripple demands.
• Leakage and Loss Characteristics — Specified leakage current of 1,030 µA and a tangent of loss angle (tan δ) of 0.2 at 20°C and 120 Hz for predictable dissipation behavior.
• Wide Operating Range — Operational from −40°C to 105°C, suitable for systems that must tolerate broad ambient and operating conditions.
• Regulatory Compliance — RoHS compliant, aligning with restricted substance requirements for electronics manufacturing.

Typical Applications

• General‑Purpose Power Supplies — Bulk smoothing and ripple handling where 100 V rating and high capacitance are required.
• Power Conversion Modules — Energy storage and decoupling in assemblies that require snap‑in mounting and high ripple current capability.
• Industrial Electronics — Long‑life capacitive support for equipment operating up to 105°C and exposed to elevated ripple currents.

Unique Advantages

• Robust High‑Voltage Bulk Storage: 100 V rating and 1,200 µF capacitance deliver substantial stored energy for demanding power circuits.
• Designed for Continuous Ripple: Rated ripple currents at both low and high frequencies (1,740 mA @120 Hz; 2,001 mA @50 kHz) enable reliable AC stress handling.
• Extended Thermal Endurance: 3,000 hours at 105°C ensures longevity in high‑temperature environments, supporting predictable maintenance intervals.
• Production‑Friendly Packaging: Snap‑in radial can and tray packing simplify assembly and handling for high‑volume manufacturing.
• Predictable Electrical Behavior: Specified tan δ (0.2 at 20°C, 120 Hz) and measured leakage current provide clear design margins for thermal and leakage budgeting.
• Regulatory Alignment: RoHS compliance supports environmental and regulatory requirements for modern electronic products.
