LGY1C123MELA30

The LGY1C123MELA30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGY series designed for long‑life, high‑reliability power applications. It delivers 12 mF capacitance at a 16 V rating in a radial, can-style snap‑in package suited for robust board mounting.

Engineered for industrial power supplies and ballast applications, this part is specified to withstand sustained ripple current at elevated temperature and is RoHS compliant.

Key Features

• Electrical specification — 12 mF capacitance at 16 V with a tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• Long‑life, high‑temperature endurance — Rated for 5,000 hours under D.C. bias plus rated ripple current at 105°C; after endurance testing capacitance change is within ±25% and leakage current remains at or below the initial specified value.
• Ripple current capability — Rated ripple current of 2.4 A at 120 Hz and 2.76 A at 50 kHz for effective filtering in power circuits.
• Thermal and frequency performance — Operating temperature range −40°C to +105°C; tangent of loss angle (tan δ) max 0.50 at 16 V (measured at 120 Hz, 20°C).
• Package & mounting — Radial, can‑style snap‑in package for secure board mounting; physical size L: 3 × D: 2.5 cm.
• Leakage behavior — Leakage current meets the series specification I ≤ 3√CV (μA) after 5 minutes’ application of rated voltage at 20°C.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies — Bulk energy storage and smoothing where long life and sustained ripple handling at elevated temperature are required.
• Ballast systems — Filtering and energy buffering in lighting ballast applications that demand dependable performance over extended duty cycles.
• General purpose power filtering — Decoupling and smoothing in equipment that operates across −40°C to +105°C and requires polarized, high‑capacitance snap‑in capacitors.

Unique Advantages

• Designed for extended high‑temperature operation — 5,000‑hour endurance at 105°C under rated ripple conditions supports reliable long‑term service in demanding environments.
• High ripple current capability — 2.4 A at 120 Hz and 2.76 A at 50 kHz reduce heating and extend service life in high‑stress power circuits.
• Robust snap‑in mounting — Radial, can‑style snap‑in package provides mechanical stability and consistent board retention for industrial assemblies.
• Wide operating temperature range — −40°C to +105°C supports use across a broad set of industrial conditions without derating beyond specified limits.
• Clear electrical limits and leakage specification — Leakage current and tan δ specifications (including the I ≤ 3√CV rule) make it straightforward to predict performance after installation and during life testing.
• RoHS compliant — Meets current RoHS requirements for restricted substances.
