LGY1J472MELA50

The LGY1J472MELA50 is a snap‑in, radial can aluminum electrolytic capacitor designed for long life and reliable performance in demanding power applications. It provides 4.7 mF capacitance at a 63 V rating with polarized snap‑in terminals for robust board mounting.

Engineered for industrial power supplies and ballast use, this capacitor is specified for continuous operation across a –40°C to 105°C range and is qualified for 5000 hours of ripple‑current endurance at 105°C, making it suitable where sustained ripple handling and thermal durability are required.

Key Features

• Long‑life high‑temperature endurance — Rated for 5000 hours of DC bias plus rated ripple current at 105°C to support extended operation in hot environments.
• Capacitance and voltage — 4.7 mF capacitance with a 63 V rated voltage and ±20% tolerance for power‑filtering and energy‑storage roles.
• High ripple current capability — Handles 2.6 A at 120 Hz and 2.99 A at 50 kHz, supporting heavy ripple conditions in power supplies and ballast circuits.
• Wide operating temperature — Specified for operation from –40°C to +105°C to accommodate industrial thermal ranges.
• Snap‑in radial can package — Snap‑in terminals and a radial can (L: 5 × D: 2.5 cm) provide secure mounting for high‑current power assemblies.
• Polarized design — Electrolytic (polar) construction appropriate for DC filtering and energy storage in power circuits.
• RoHS compliant — Meets RoHS directives (2011/65/EU, (EU)2015/863) for restricted substances.
• Clear marking — Printed with white lettering on a black sleeve for straightforward identification.

Typical Applications

• Industrial power supplies — Bulk filtering and ripple smoothing where sustained ripple current and long thermal endurance are required.
• Ballast circuits — Energy storage and filtering in lighting ballast designs that demand reliable performance at elevated temperatures.
• General purpose power electronics — DC link, smoothing, and decoupling uses in equipment requiring a polarized, snap‑in aluminum electrolytic.

Unique Advantages

• Proven long‑life specification — 5000 hours at 105°C under rated ripple current provides predictable lifetime behavior for maintenance planning.
• High ripple handling across frequencies — Specified ripple current values at 120 Hz and 50 kHz support performance in both low and high frequency power stages.
• Robust snap‑in mounting — Snap‑in terminals offer mechanical stability for high‑current, vibration‑prone assemblies.
• Wide temperature range — –40°C to +105°C operation supports deployment in varied industrial environments.
• Regulatory compliance — RoHS compliance simplifies integration into products targeting restricted‑substance requirements.
• Compact power form factor — 5 × 2.5 cm can size balances capacitance and board space for power supply designs.
