LGU1J182MELZ

The LGU1J182MELZ is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGU series, rated at 63 V with a nominal capacitance of 1800 µF (±20%). It is built for general‑purpose applications that require substantial capacitance, measurable ripple handling, and long endurance under elevated temperatures.

Key value comes from its combination of high ripple current capability (1.58 A at 120 Hz; 1.817 A at 50 kHz), a wide operating range from −40 °C to +105 °C, and a rated endurance of 3000 hours at 105 °C, making it suitable for production deployment in systems that demand reliable power filtering and bulk capacitance.

Key Features

• Capacitance & Voltage  1800 µF nominal capacitance at a rated voltage of 63 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• High Ripple Current Capability  Rated ripple current of 1.58 A at 120 Hz (low frequency) and 1.817 A at 50 kHz (high frequency), supporting effective filtering under AC and switching conditions.
• Temperature Range & Endurance  Operating temperature range of −40 °C to +105 °C with an endurance rating of 3000 hours at 105 °C when subjected to rated ripple current and DC bias.
• Loss Characteristics (tan δ)  Specified tan δ (DF) of 0.25 maximum at 20 °C and 120 Hz for predictable dissipation behavior.
• Leakage Current  Leakage current specified at 1010 µA after standard voltage application conditions.
• Package & Mounting  Snap‑in radial can package (φ22 × 30 L) designed for secure board mounting; supplied in tray packing for production use.
• Compliance & Production Status  RoHS compliant and indicated as mass production status for supply continuity.

Typical Applications

• General‑Purpose Electronics  Provides bulk capacitance and smoothing for circuits that require a 63 V, 1800 µF capacitor in a snap‑in form factor.
• Power Supply Filtering  Used for reservoir and smoothing tasks where high ripple current handling (1.58 A at 120 Hz; 1.817 A at 50 kHz) is needed to maintain voltage stability.
• Industrial & Commercial Systems  Suited to systems operating across −40 °C to +105 °C and requiring long‑term endurance (3000 hours at 105 °C) under rated ripple and DC bias.

Unique Advantages

• High ripple tolerance: The specified low‑ and high‑frequency ripple currents support demanding filtering and decoupling tasks without frequent replacement.
• Long endurance at elevated temperature: 3000 hours rated life at 105 °C underlines durability for applications exposed to continuous thermal stress.
• Predictable dissipation behavior: Specified tan δ (0.25 at 20 °C, 120 Hz) helps designers estimate loss and heating for thermal and reliability planning.
• Wide operating range: −40 °C to +105 °C allows deployment across a broad set of environments where temperature extremes are encountered.
• Production-ready packaging: Tray packing and mass production status support efficient procurement and assembly for volume manufacturing.
• RoHS compliant: Meets regulatory requirements for lead‑free manufacturing and environmental conformity.
