LGJ2Z121MELY15

The LGJ2Z121MELY15 is an aluminum electrolytic, snap‑in terminal capacitor in Nichicon’s LGJ series. It provides 120 µF capacitance at a 180 V rating in a compact, radial can (φ20 × 15 mm) package designed for general‑purpose electronic assemblies.

Engineered for robustness, this polarized snap‑in capacitor supports an operating temperature range of –40°C to +105°C and a stated lifetime of 2000 hours at 105°C, making it suitable for assemblies that require stable capacitance, defined ripple handling, and a compact low‑profile form factor.

Key Features

• Capacitance & Voltage: 120 µF capacitance rated at 180 V for bulk energy storage and DC link applications requiring polarized electrolytic capacitance.
• Package & Mounting: Radial, can‑style snap‑in package (φ20 × 15 mm) for secure panel or PCB mounting in compact assemblies.
• Temperature & Lifetime: Operates from –40°C to +105°C with a rated lifetime of 2000 hours at 105°C, enabling use in higher‑temperature environments.
• Ripple Current Performance: Specified ripple current of 500 mArms at 120 Hz and 750 mArms at 50 kHz, supporting AC ripple handling across low and high frequencies.
• Polarization & Tolerance: Polarized electrolytic construction with capacitance tolerance of ±20% (–20% to +20%).
• Leakage Characteristic: Leakage current conforms to the manufacturer’s specification I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20°C (per series datasheet statement).
• Identification: Marked with white lettering on a black sleeve for clear part identification.

Typical Applications

• General‑purpose electronic assemblies: Ideal where a compact, polarized capacitor is required for general‑purpose circuits and board‑level power components.
• Power supply filtering: 120 µF at 180 V with defined ripple ratings supports filtering and smoothing tasks in power modules and DC rails.
• Industrial and commercial equipment: The –40°C to +105°C range and 2000‑hour life at 105°C suit equipment exposed to elevated operating temperatures.

Unique Advantages

• Compact low‑profile package: φ20 × 15 mm snap‑in can delivers significant capacitance in a small footprint for space‑constrained designs.
• Clear thermal specification: Rated operation to +105°C and a 2000‑hour endurance at that temperature provide predictable aging and replacement planning.
• Practical ripple handling: Separate ripple current ratings at 120 Hz and 50 kHz allow designers to size the capacitor against expected AC stress across frequency ranges.
• Defined leakage behavior: Leakage current bound by the manufacturer’s I ≤ 3√CV formula offers a measurable parameter for power‑loss and standby calculations.
• Snap‑in mounting for secure fit: Snap‑in terminals simplify mechanical retention in high‑vibration or densely populated assemblies.
