LGU1K392MELA

The LGU1K392MELA is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series. It delivers 3,900 µF capacitance at an 80 V rating in a radial, snap‑in can designed for general‑purpose applications.

Engineered for elevated operating conditions, this part offers a wide operating temperature range (‑40°C to 105°C), robust ripple handling, and a 3,000‑hour endurance at 105°C—features that support reliable bulk energy storage and smoothing in general‑purpose power designs.

Key Features

• Capacitance & Voltage — 3,900 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Loss Angle (tan δ) — tanδ = 0.20 measured at 20°C, 120 Hz (specified for 80 V rating).
• Ripple Current Performance — Low‑frequency ripple current 2.92 A at 120 Hz and high‑frequency ripple current 3.358 A at 50 kHz, supporting continuous AC ripple stress handling.
• Leakage Current — Specified leakage current of 1,670 µA (after standard test conditions).
• High‑Temperature Endurance — Rated for 3,000 hours at 105°C under rated ripple/current conditions per LGU series endurance specification.
• Operating Temperature Range — −40°C to +105°C to accommodate a broad range of ambient conditions.
• Package & Mounting — Radial, snap‑in can package (φ25 × 50L) optimized for secure chassis or board mounting; supplied in tray packing and listed as mass production.
• Environmental Compliance — RoHS compliant per the product specification.

Typical Applications

• General‑purpose power designs — Bulk capacitance for smoothing and energy storage where an 80 V, 3,900 µF snap‑in capacitor is specified.
• Power supply filtering — Effective for designers needing high ripple current capability and long endurance at elevated temperatures.
• Industrial and equipment electronics (general purpose) — Suitable for general‑purpose circuits requiring robust temperature and endurance performance.

Unique Advantages

• High capacitance density: 3,900 µF at 80 V provides substantial bulk energy storage in a compact φ25 × 50L package.
• Designed for elevated-temperature duty: 3,000 hours endurance at 105°C ensures sustained performance under prolonged thermal stress.
• Strong ripple handling: Specified LF and HF ripple currents (2.92 A at 120 Hz, 3.358 A at 50 kHz) reduce overheating risk in high‑ripple environments.
• Clear electrical characterization: Defined tanδ (0.20 at 20°C, 120 Hz) and leakage current (1,670 µA) simplify selection and thermal budgeting.
• Practical mounting and supply: Snap‑in radial can and tray packing support straightforward assembly and inventory management.
• RoHS compliant: Meets environmental directive requirements for restricted substances.
