LGU2F151MELZ

The LGU2F151MELZ is a snap-in terminal aluminum electrolytic capacitor designed for high-voltage, general-purpose power applications. It combines a 315 V rated voltage with 150 µF capacitance and a compact φ22 × 30 mm can for robust DC filtering and energy storage.

Engineered for sustained operation at elevated temperatures, this capacitor offers long endurance under rated ripple current and is supplied in tray packaging for reliable mass-production assembly.

Key Features

• Electrical Performance: 150 µF nominal capacitance with ±20% tolerance and a 315 V rated voltage; polarized design for DC applications.
• Low Loss / Dissipation: Specified tan δ of 0.15 (measurement at 120 Hz, 20°C) to minimize AC losses in filtering and smoothing duties.
• High Ripple Capability: Rated ripple current of 820 mA at 120 Hz (low frequency) and 1.173 A at 50 kHz (high frequency), supporting demanding ripple conditions.
• Endurance and Thermal Stability: Lifetime rated at 3000 hours at 105°C with an operating temperature range of −25°C to +105°C.
• Package and Mounting: Snap‑in radial can (φ22 × 30 mm / L: 3.0 cm × D: 2.2 cm) packaged in trays for production-friendly handling and secure board mounting.
• Leakage Current: Low leakage current specified at 650 µA, suitable for stable DC bias applications.
• Compliance and Availability: RoHS compliant and stated as available for mass production.

Typical Applications

• High-voltage DC power supplies: Bulk smoothing and DC link filtering where a 315 V rated capacitor with high ripple capability is required.
• Industrial power electronics: Energy storage and decoupling in industrial converters and auxiliary power modules operating at elevated temperatures.
• Inverters and motor drives: DC-link filtering and ripple handling to support steady operation under continuous ripple stress.

Unique Advantages

• High voltage handling: 315 V rating enables use in medium‑voltage DC circuits and higher-voltage power rails.
• Designed for continuous ripple load: Rated ripple currents at both low and high frequencies support designs with varied switching profiles.
• Long endurance at elevated temperature: 3000 hours at 105°C provides predictable lifetime performance in hot operating environments.
• Compact, production-ready package: φ22 × 30 mm snap‑in can and tray packing simplify PCB integration and assembly for mass production runs.
• Low dissipation factor: tan δ = 0.15 at 120 Hz reduces heat generation and improves efficiency in AC-stressed circuits.
• RoHS compliant: Meets environmental requirements for modern electronic manufacturing workflows.
