LGC2H151MELZ40

The LGC2H151MELZ40 is a snap‑in terminal aluminum electrolytic capacitor designed for compact, long‑life power applications. It combines a 500 V rated voltage with 150 µF capacitance in an ultra‑smaller‑sized case (one rank smaller than LGX), making it suited for equipment downsizing and space‑constrained designs.

Engineered for demanding thermal and ripple environments, this polarized radial can provides 5000 hours of endurance at 105°C and is compliant with RoHS directives, offering a balance of high voltage capability, reliable long‑term performance, and compact packaging.

Key Features

• Core Type  Aluminum electrolytic, polarized construction providing 150 µF capacitance at a 500 V rating.
• High‑temperature long life  Rated for operation from −40°C to +105°C with an endurance specification of 5000 hours at 105°C under DC bias plus rated ripple current.
• Compact snap‑in package  Radial, can‑type snap‑in mounting for secure board installation; physical size approximately φ22 × 40 mm (L: 4 × D: 2.2 cm).
• Ripple current handling  Rated ripple current of 1.11 A at 120 Hz and 1.587 A at 50 kHz, with frequency coefficients provided to scale ripple with operating frequency.
• Electrical stability and loss  Capacitance tolerance ±20% (at 120 Hz, 20°C) and tangent of loss angle (tan δ) ≤ 0.25 (120 Hz, 20°C).
• Leakage current specification  Leakage current defined as I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20°C; specific part leakage ~0.82 mA as listed for the 150 µF/500 V size.
• Environmental compliance  Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Compact high‑voltage power modules  A 500 V, 150 µF snap‑in capacitor for designs that require reduced case size without sacrificing voltage capability.
• Equipment downsizing  Specifically suited for projects where a smaller case than the LGX family enables reduced enclosure footprint and board area.
• High‑temperature installations  Long‑life performance (5000 hours at 105°C) for applications exposed to elevated operating temperatures.
• Snap‑in board mounting  Radial snap‑in configuration for secure mechanical retention in vertical PCB assemblies and power stacks.

Unique Advantages

• Ultra‑smaller case size: One rank smaller than the LGX series, enabling tighter packaging and reduced system volume.
• High voltage capability: 500 V rating supports higher‑voltage bus and power applications without series stacking.
• Designed for long life at temperature: 5000 hours endurance at 105°C ensures sustained performance in thermally stressed environments.
• Measured ripple performance: Rated ripple current values (1.11 A at 120 Hz; 1.587 A at 50 kHz) and frequency coefficients allow predictable ripple handling across frequencies.
• Clear electrical limits: Leakage current defined by I ≤ 3√CV (µA) and tan δ ≤ 0.25 provide verifiable electrical characteristics for design validation.
• RoHS compliance: Meets 2011/65/EU and (EU)2015/863 restrictions for materials, simplifying environmental compliance for finished products.
