LGC2H181MELZ45

The LGC2H181MELZ45 is a snap‑in terminal aluminum electrolytic capacitor rated at 500 V and 180 µF. It is an ultra‑smaller‑sized, long‑life design intended for general‑purpose use and for applications requiring equipment downsizing.

Key attributes include snap‑in radial can packaging, a wide operating temperature range from −40 °C to +105 °C, and a 5,000‑hour endurance at 105 °C, providing predictable performance in compact, high‑voltage designs.

Key Features

• Capacitance and Voltage — 180 µF rated capacitance at 500 V for high‑voltage energy storage and filtering in a compact package.
• Temperature and Long Life — Rated for −40 °C to +105 °C with endurance of 5,000 hours at 105 °C under DC bias plus rated ripple current.
• Compact, Snap‑In Package — Radial, snap‑in can package (L: 45 mm × D: 22 mm) designed as one rank smaller case than LGX to support equipment downsizing.
• Ripple Handling — Rated ripple current of 1,250 mArms at 120 Hz (1250 mArms for 22 × 45 mm size) with frequency coefficients available for higher frequencies.
• Electrical Characteristics — Capacitance tolerance ±20% (at 120 Hz, 20 °C), polarized construction, and leakage current specified as I ≤ 3√(C·V) μA after 5 minutes at 20 °C.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power modules — Use where a high‑voltage snap‑in electrolytic capacitor is required for energy storage or smoothing in compact assemblies.
• Equipment downsizing — One rank smaller case size than LGX makes this part a fit for systems targeting reduced footprint without changing rated voltage or capacitance.
• High‑temperature environments — Suitable for applications that need continuous operation up to 105 °C with a qualified 5,000‑hour life expectation under rated conditions.

Unique Advantages

• High‑voltage capability: 500 V rating provides headroom for high‑voltage circuits while maintaining a compact form factor.
• Space‑efficient sizing: Ultra‑smaller case (one rank smaller than LGX) helps reduce system footprint during board layout and mechanical design.
• Designed for elevated temperatures: Rated to −40 °C to +105 °C with a 5,000‑hour endurance at 105 °C for long‑life operation under thermal stress.
• Snap‑in mounting: Radial, snap‑in terminal style enables robust mechanical retention for power applications and straightforward PCB assembly.
• Measurable ripple performance: Rated ripple current (1,250 mArms at 120 Hz for this size) and provided frequency coefficients allow designers to size for expected ripple conditions.
• RoHS compliance: Conforms to RoHS (2011/65/EU, (EU)2015/863), simplifying use in regulated product lines.
