LGY1C183MELZ50

The LGY1C183MELZ50 is an aluminum electrolytic capacitor in Nichicon’s LGY series featuring a snap-in terminal (radial can) package. It is designed for long-life, high-reliability power applications, with a specified endurance of 5000 hours under rated ripple at 105°C.

Targeted at industrial power supplies and ballast applications, this polarized capacitor provides high capacitance in a robust snap-in form factor for systems that require dependable smoothing and bulk energy storage across a wide temperature range.

Key Features

• Long-life endurance – Rated for 5000 hours at 105°C when DC bias plus rated ripple current is applied, with defined limits for capacitance change, tan δ and leakage current.
• High capacitance and voltage – 18 mF capacitance at a 16 V rated voltage, suited for bulk filtering and energy storage.
• Snap-in / radial can package – Snap-in terminal type for secure, high-current board mounting in through-hole assemblies.
• Operating temperature range – Specified for −40°C to +105°C to support industrial thermal environments.
• Ripple current capability – Rated ripple current of 3 A at 120 Hz and 3.45 A at 50 kHz to support power supply smoothing and high-frequency ripple conditions.
• Leakage current specification – Leakage current conforms to I ≤ 3√CV (μA) after 5 minutes’ application of rated voltage at 20°C, as defined in the series datasheet.
• Tolerance and polarization – Capacitance tolerance of ±20% and polarized construction for correct orientation in DC circuits.
• RoHS compliant – Meets the RoHS directive (2011/65/EU and (EU)2015/863) for restricted substances.
• Package dimensions – Height (seated) maximum 1.969 inch; size dimension L: 5 × D: 2.2 cm for board layout and mechanical planning.
• Frequency ripple coefficient – Frequency coefficients for rated ripple current are provided for 50 Hz through 50 kHz and above (e.g., 0.88 at 50 Hz, 1.00 at 120 Hz, 1.15 at 50 kHz for 16–100 V ratings).

Typical Applications

• Industrial power supplies – Bulk filtering and smoothing where long-term ripple endurance and high capacitance at 16 V are required.
• Ballast circuits – Designed for ballast applications where reliable operation and sustained ripple handling at elevated temperature are important.
• General-purpose power conditioning – Suitable for general-purpose DC energy storage and smoothing in through-hole, high-reliability designs.

Unique Advantages

• Proven long-life performance: 5000-hour ripple endurance at 105°C reduces the need for frequent replacement in high-temperature, high-stress installations.
• High ripple handling: Specified ripple currents at both low and high frequencies support effective filtering across typical switching and mains frequencies.
• Robust mechanical mounting: Snap-in terminal construction provides secure board attachment for applications with higher vibration or current demands.
• Wide ambient range: −40°C to +105°C rating enables deployment in varied industrial thermal environments.
• Clear electrical limits: Defined leakage, tan δ and endurance criteria allow predictable design margins for power electronics systems.
• Regulatory compliance: RoHS conformity supports environmental requirements for commercial and industrial products.
