LGU1H332MELZ

The LGU1H332MELZ is a snap-in terminal aluminum electrolytic capacitor rated at 50 V with a nominal capacitance of 3300 µF (3.3 mF) and ±20% tolerance. It is a general-purpose industrial capacitor designed for applications requiring elevated temperature endurance and sustained ripple handling.

Key value points include a 105°C operating temperature range with 3000 hours endurance, specified low-frequency and high-frequency ripple current capability, and a compact snap-in can (φ22 × 35 mm) for robust board mounting and automated assembly in tray packing.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 µF) nominal capacitance at a rated voltage of 50 V with ±20% tolerance, suited for bulk energy storage and decoupling in general-purpose designs.
• High-temperature Endurance — Rated for operation from −40°C to +105°C with an endurance specification of 3000 hours at 105°C, providing predictable performance under elevated-temperature stress.
• Ripple Current Performance — Specified ripple current of 1.98 A at 120 Hz (low frequency) and 2.277 A at 50 kHz (high frequency), supporting applications with continuous AC ripple exposure.
• Leakage and Dissipation Factor — Leakage current specified at 1210 µA and a tangent of loss angle (tanδ) of 0.30 measured at 20°C and 120 Hz, enabling quantifiable loss and leakage budgeting in power designs.
• Package & Mounting — Radial, snap-in can package (φ22 × 35 mm) for secure insertion and mechanical stability on power PCBs; supplied in tray packing for production scalability.
• Regulatory Compliance — RoHS compliant, aligning with regulatory requirements for restricted substances in many commercial and industrial applications.

Typical Applications

• General-purpose power filtering — Bulk filtering and smoothing where 3300 µF at 50 V is required and where long-term operation at up to 105°C is expected.
• High-ripple power modules — Circuits that require sustained ripple handling, leveraging the specified 1.98 A (120 Hz) and 2.277 A (50 kHz) ripple current ratings.
• Industrial and commercial equipment — Power supplies and control modules that benefit from a compact snap-in radial can and a 3000-hour endurance rating at 105°C.

Unique Advantages

• Designed for elevated-temperature duty — 3000 hours endurance at 105°C provides predictable aging and performance for high-temperature deployments.
• Measured ripple capability across frequency — Explicit low- and high-frequency ripple current specifications allow accurate thermal and ripple budgeting in designs.
• Quantified leakage and dissipation — Specified leakage current (1210 µA) and tanδ (0.30 at 20°C, 120 Hz) help engineers manage standby losses and dissipation margins.
• Production-ready packaging — Tray packing and mass production status support volume manufacturing and repeatable assembly processes.
• Compact, mechanically robust form factor — Snap-in radial can (φ22 × 35 mm) provides secure board retention and straightforward mounting on power PCBs.
• RoHS compliance — Meets RoHS directive requirements for restricted substances used in a wide range of commercial and industrial products.
