LGU2D122MELB

The LGU2D122MELB is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGU series. It provides 1.2 mF capacitance at a 200 V rating in a radial, snap-in can package designed for general-purpose electronic power applications.

Engineered for sustained ripple handling and long-term endurance, this part targets designs that require high ripple-current capability and reliable operation across a wide temperature range up to 105°C.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with a tolerance of ±20% (measured at 120 Hz, 20°C); rated voltage 200 V.
• Snap‑in Radial Can — Snap-in terminal package (radial, can - snap-in) for secure PCB mounting; nominal dimensions φ30 × 40L (L: 4 × D: 3 cm).
• High Ripple‑Current Capability — Rated low-frequency ripple current of 2.65 A at 120 Hz and high-frequency ripple current of 3.975 A at 50 kHz (as specified for this part).
• Endurance at Elevated Temperature — Designed to withstand 3000 hours of rated ripple current at 105°C; endurance criteria include capacitance within ±20% and leakage not exceeding initial specified values after test.
• Loss Tangent (tan δ) — Measured at 120 Hz, 20°C; for the 160–420 V group the maximum tan δ is 0.15, consistent with series specifications for this voltage class.
• Leakage Current — Specified leakage current of 1460 µA (measured after application of rated voltage at 20°C, per series test conditions).
• Operating Temperature — Rated for −40°C to +105°C operation.
• Compliance & Packaging — RoHS‑compliant; supplied in tray packing and currently in mass production.

Typical Applications

• General‑purpose power systems — Bulk capacitance and smoothing for equipment operating up to 200 V where sustained ripple handling and endurance at elevated temperatures are required.
• Power conversion modules — DC-link and energy storage in power supplies and converters that benefit from high ripple‑current capability and a compact snap‑in package.
• Industrial electronics — Long‑life filtering and decoupling in industrial equipment designed to operate across −40°C to +105°C.

Unique Advantages

• Designed for sustained ripple duty: Rated ripple currents of 2.65 A at 120 Hz and 3.975 A at 50 kHz support effective ripple absorption in power circuits.
• Proven high‑temperature endurance: 3000 hours at 105°C under rated ripple current ensures predictable aging behavior and retention of electrical characteristics.
• Specification‑driven performance: Capacitance tolerance (±20%), tan δ limits (0.15 max for the 160–420 V group), and defined leakage current offer measurable, verifiable parameters for design verification.
• Robust mounting form factor: Snap‑in radial can simplifies board assembly for power modules and aids mechanical stability in high‑current layouts.
• Regulatory compliance and production readiness: RoHS‑compliant construction and tray packing, with the part in mass production for stable sourcing.
