LGG2C122MELC25

The LGG2C122MELC25 is a 1200 µF, 160 V aluminum electrolytic capacitor in a snap‑in terminal (radial can) package from Nichicon’s LGG series. Designed for general‑purpose power applications, it delivers high capacitance density in a compact φ35 × 25 mm can and is optimized for environments requiring elevated temperature endurance.

Key attributes include a 105°C rated temperature, a 2000‑hour endurance at 105°C, RoHS compliance, and tray packing for production handling. Typical use cases include bulk energy storage, smoothing and decoupling in power supplies, and applications that require reliable high‑voltage capacitance in a snap‑in mount.

Key Features

• Capacitance and Voltage — 1.2 mF (1200 µF) rated at 160 V for bulk energy storage and smoothing in medium‑voltage power rails.
• Snap‑In Mounting — Snap‑in terminal (radial, can – snap‑in) construction for secure PCB retention and simplified assembly in power modules and chassis‑mounted designs.
• Compact, High‑Density Package — Case size φ35 × 25 mm provides a high capacitance-to-volume ratio for space‑constrained designs.
• Thermal Endurance — Rated operating range −40°C to +105°C with an endurance rating of 2000 hours at 105°C under rated DC bias plus ripple current.
• Ripple Current Capability — Low‑frequency ripple: 2.3 A at 120 Hz; high‑frequency ripple: 3.45 A at 100 kHz, enabling reliable handling of AC ripple across a range of switching and line‑frequency conditions.
• Leakage and Dissipation — Leakage current specified at 1310 µA; tangent of loss angle (tan δ) 0.15 (measured at 20°C, 120 Hz) to help assess dissipation and ESR‑related behavior.
• Tolerance and Polarization — Capacitance tolerance −20% to +20%; polarized device for correct orientation in DC circuits.
• Compliance and Packaging — RoHS‑compliant and available in tray packing for streamlined production handling; product is in mass production.

Typical Applications

• Power Supplies — Bulk filtering and smoothing on medium‑voltage DC rails where 160 V rated capacitance and high ripple capability are required.
• Industrial Power Modules — Energy storage and decoupling in motor drives, inverters, and power control assemblies operating up to 105°C.
• Switching Converters — Input/output filtering for switch‑mode power supplies that demand high ripple endurance at both low and high frequencies.
• Chassis‑Mounted Power Systems — Board retainment and vibration‑resilient snap‑in mounting for ruggedized equipment with space constraints.

Unique Advantages

• High Capacitance in a Compact Footprint: 1200 µF in a φ35 × 25 mm package reduces board area for designs that need substantial energy storage without large cans.
• Broad Ripple Handling: Specified ripple currents at 120 Hz and 100 kHz (2.3 A and 3.45 A respectively) provide predictable performance across transformer‑fed and switching environments.
• Temperature and Lifetime Assurance: 2000 hours endurance at 105°C gives a defined life expectation for elevated‑temperature applications.
• Measurable Dissipation and Leakage: tan δ (0.15 at 20°C, 120 Hz) and 1310 µA leakage current provide clear electrical baselines for thermal and power‑loss budgeting.
• Production‑Ready Packaging: Tray packing and mass‑production availability support repeatable procurement and assembly for volume programs.
• Regulatory Compliance: RoHS compliance ensures the part meets common environmental requirements for electronic assemblies.
