LLS1J182MELZ

The LLS1J182MELZ is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LLS series. It is an 1800 µF, 63 V polarized capacitor designed for general-purpose electronic applications where radial can snap-in mounting is preferred.

Engineered to deliver steady performance across a -40°C to 85°C operating range, this part offers defined ripple-current capacity, controlled dissipation factor, RoHS compliance, and 3000 hours of endurance at 85°C for reliable long-term operation.

Key Features

• Capacitance & Voltage — 1800 µF (1.8 mF) rated capacitance at 63 V with ±20% tolerance.
• Package & Mounting — Snap-in terminal type in a radial can package; physical dimensions: φ22 × 25 mm (L: 2.5 cm × D: 2.2 cm).
• Ripple Current Capability — Rated ripple current of 1.9 A at 120 Hz (low frequency) and 2.185 A at 50 kHz (high frequency) to support AC ripple handling within its ratings.
• Dissipation Factor — tan δ (DF) of 0.25 (measurement at 120 Hz, 20°C) for specified dielectric losses at the rated voltage.
• Leakage Current — Specified leakage current of 1010 µA for the part; series datasheet also provides the leakage guideline I ≤ 3√CV (after 5 minutes at rated voltage, 20°C).
• Endurance & Reliability — Withstanding rated ripple current under DC bias for 3000 hours at 85°C; series endurance limits include capacitance change within ±20%, tan δ ≤ 200% of initial spec, and leakage current ≤ initial specified value after the endurance test.
• Operating Temperature — Specified operating range from -40°C to +85°C.
• Compliance & Availability — RoHS compliant, tray packing, and in mass production.

Typical Applications

• General-Purpose Power Circuits — Used where a snap-in aluminum electrolytic capacitor is required for bulk capacitance and ripple handling in general electronic circuits.
• Industrial and Commercial Equipment — Applicable to general-purpose equipment operating within -40°C to 85°C that require reliable long-term capacitor endurance at elevated temperature.
• Chassis-Mounted Power Modules — Snap-in radial can packaging suits secure chassis or panel mounting in assemblies needing 63 V, 1800 µF capacitance.

Unique Advantages

• High rated capacitance at 63 V: 1800 µF provides substantial stored charge for smoothing and bulk energy needs within the rated voltage.
• Defined ripple handling: 1.9 A (120 Hz) and 2.185 A (50 kHz) ripple-current ratings allow designers to match the part to expected AC stress levels.
• Long 85°C endurance: 3000 hours of rated operation at 85°C with specified limits on capacitance change, tan δ, and leakage current supports durability in sustained elevated-temperature environments.
• Compact snap-in form factor: φ22 × 25 mm radial can with snap-in terminals simplifies mechanical retention and board/chassis integration.
• Measured dissipation factor: tan δ of 0.25 at 120 Hz gives a quantified loss parameter for thermal and AC-loss budgeting.
• RoHS compliant and production-ready: Tray packing and mass-production status support procurement and assembly workflows while meeting environmental directives.
