LGU1K102MELZ

The LGU1K102MELZ is a Nichicon LGU series snap-in aluminum electrolytic capacitor rated at 1000 µF and 80 V with a ±20% tolerance. It is a polarized, radial can (snap-in) package designed for general-purpose power applications that require bulk capacitance, stable performance across a broad temperature range, and sustained ripple endurance.

Key value propositions include high ripple-current capability, a long endurance rating at elevated temperature, a compact 22 mm × 25 mm footprint, and RoHS compliance—making it suitable for production deployments where reliability and repeatable performance are required.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance at a rated voltage of 80 V with ±20% tolerance, suitable for bulk energy storage and smoothing in higher-voltage rails.
• Snap-in Radial Can Package — Snap-in terminal type in a φ22 × 25 mm can simplifies PCB mounting for power assemblies and vertical mounting configurations.
• High Temperature Endurance — Rated for operation from −40 °C to +105 °C with a life specification of 3000 hours at 105 °C under rated ripple conditions.
• Ripple Current Performance — Low-frequency ripple current of 1.29 A at 120 Hz and high-frequency ripple current of 1.484 A at 50 kHz, enabling effective handling of both mains-frequency and switching-frequency ripple.
• Low Dissipation Factor — tan δ (DF) of 0.2 measured at 20 °C, 120 Hz, supporting efficient energy handling with controlled losses.
• Leakage Current — Specified leakage current of 840 µA (after rated voltage applied), enabling predictable standby and quiescent characteristics in power designs.
• Production & Packaging — Mass-production status with tray packing to support procurement and automated assembly workflows.
• RoHS Compliant — Meets RoHS environmental requirements as indicated in product data.

Typical Applications

• Power supply bulk smoothing — Bulk energy storage and ripple smoothing on DC rails up to 80 V, taking advantage of 1000 µF capacitance and rated ripple current.
• Switch-mode power supplies (SMPS) — Output filtering and energy buffering where high-frequency ripple handling (1.484 A at 50 kHz) and temperature endurance are required.
• Industrial power modules — Pulse and continuous-power filtering in industrial converters and control equipment, leveraging the 105 °C endurance rating and 3000 h life at elevated temperature.
• Uninterruptible power systems and backup — Bulk capacitance for short-term energy storage and smoothing in higher-voltage backup subsystems.

Unique Advantages

• Durable high-temperature life — 3000 hours at 105 °C under rated ripple current provides predictable long-term behavior in hot operating environments.
• Versatile ripple handling — Separate low- and high-frequency ripple current specs let designers align capacitor selection with both mains and switching-frequency requirements.
• Compact, assembly-friendly form — φ22 × 25 mm snap-in can offers a compact footprint and straightforward PCB integration for vertical power layouts.
• Measured loss characteristics — Specified tan δ (0.2 at 120 Hz, 20 °C) gives designers a concrete loss parameter for thermal and efficiency calculations.
• predictable leakage behavior — Defined leakage current (840 µA) enables accurate quiescent current budgeting and voltage-holding expectations.
• Production-ready supply — Mass production status and tray packing facilitate procurement and volume assembly planning.
