LGY1K152MELZ35

The LGY1K152MELZ35 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGY long-life assurance series. It provides 1.5 mF (1500 µF) capacitance at an 80 V rating and is designed for demanding industrial power applications that require dependable performance at elevated temperatures.

Built for extended operation, this radial can (snap-in) capacitor is RoHS compliant and rated for operation from –40 °C to +105 °C, with a specified life of 5000 hours at 105 °C under rated ripple conditions.

Key Features

• Capacitance & Voltage — 1.5 mF (1500 µF) rated at 80 V, with capacitance tolerance ±20% (at 120 Hz, 20 °C).
• High-temperature long life — Specified endurance of 5000 hours at 105 °C when DC bias plus rated ripple current is applied; capacitance change remains within ±25% after endurance testing.
• Snap-in radial can package — Snap-in terminal type and radial, can-style package provide secure mechanical mounting for power assemblies and PCB installations.
• Wide operating range — Rated for operation from –40 °C to +105 °C to cover a broad range of industrial environments.
• Ripple current performance — Rated ripple current: 1.6 A at 120 Hz and 1.84 A at 50 kHz; frequency coefficients are specified (e.g., 0.88 at 50 Hz, 1.00 at 120 Hz, 1.15 at 1 kHz and above) for accurate ripple derating across frequencies.
• Leakage and dissipation characteristics — Leakage current defined by I ≤ 3√(C·V) µA after 5 minutes at 20 °C; tangent of loss angle (tan δ) for 80 V rating is specified (max. 0.20 at 120 Hz, 20 °C).
• Compact footprint — Physical size L: 3.5 × D: 2.2 cm with a marked sleeve (white on black) for clear identification.
• Regulatory — RoHS compliant as part of the LGY series.

Typical Applications

• Industrial power supplies — Bulk energy storage and smoothing where long life at elevated temperatures is required.
• Ballast applications — Designed for use in ballast circuits as indicated in the LGY series documentation.
• General-purpose power filtering — Filtering and decoupling in industrial equipment and power assemblies that operate up to 105 °C.

Unique Advantages

• Long-life assurance: 5000 hours endurance at 105 °C provides predictable aging characteristics for maintenance planning and system reliability.
• High-voltage capability: 80 V rating enables use in higher-voltage power rails without needing multiple lower-voltage capacitors in series.
• Frequency-aware ripple handling: Specified ripple currents at 120 Hz and 50 kHz plus detailed frequency coefficients let designers size ripple margins accurately across operating frequencies.
• Robust thermal range: –40 °C to +105 °C operation supports a variety of industrial environments and elevated-temperature enclosures.
• Secure snap-in mounting: Radial snap-in terminals simplify installation in power supply assemblies and provide mechanical stability for vibration-prone applications.
• Standards-based electrical limits: Leakage current and tan δ are specified with measurable limits and test conditions, enabling clear pass/fail criteria during validation.
