LAR2W181MELZ45

The LAR2W181MELZ45 is an aluminum electrolytic, snap‑in terminal capacitor designed for general purpose applications that require high voltage and robust endurance. It provides 180 µF capacitance at a 450 V rating in a radial, snap‑in can (22 mm diameter × 45 mm length) package and is supplied in tray packing for production use.

Engineered for sustained operation up to 105°C, this part combines a high voltage rating, defined ripple current capability and controlled loss (tan δ) for reliable performance in demanding environments.

Key Features

• Rated Capacitance & Voltage — 180 µF capacitance at a 450 V rated voltage, suited to high‑voltage, high‑energy storage needs within general purpose designs.
• Snap‑in Terminal, Radial Can Package — Snap‑in mounting for secure chassis or PCB retention; package dimensions L: 4.5 cm × D: 2.2 cm (45 mm × 22 mm).
• Temperature & Endurance — Operates from −25°C to +105°C with an endurance specification of 2000 hours at 105°C under rated ripple current conditions.
• Defined Electrical Loss — tan δ ≤ 0.20 at 20°C and 120 Hz for the 450 V rating, enabling predictable dissipation characteristics.
• Leakage & Ripple Current — Specified leakage current 850 µA and rated ripple currents of 870 mA at 120 Hz (low frequency) and 1.244 A at 50 kHz (high frequency) for reliable ripple handling.
• Polarized Type & Tolerance — Polarized electrolytic construction with capacitance tolerance ±20% at 120 Hz, 20°C.
• RoHS Compliant — Meets RoHS directive requirements for material compliance.
• Series Performance Traits — Part of the LAR series: designed to withstand 2000 hours application of rated ripple current at 105°C and to reduce incidence of shorting under overvoltage conditions (rated voltage × 1.5) as defined by the series safety performance testing.

Typical Applications

• General Purpose High‑Voltage Circuits — Provides 180 µF at 450 V for designs requiring high‑voltage energy storage and decoupling in general purpose equipment.
• Production Assemblies — Tray packing and snap‑in terminals support efficient handling and secure installation in mass production builds.
• Environments Requiring Extended Endurance — Rated 2000 hours at 105°C for applications where sustained elevated‑temperature operation and ripple endurance are required.

Unique Advantages

• High Voltage Capacity: 450 V rating enables use in higher‑voltage designs without series stacking of lower‑voltage capacitors.
• Long Endurance at Elevated Temperature: 2000 hours at 105°C under rated ripple current provides a defined reliability baseline for thermal stress tolerance.
• Predictable Loss Characteristics: tan δ specified at 0.20 (120 Hz, 20°C) for the 450 V rating helps with thermal and dissipation planning.
• Dual‑Frequency Ripple Data: Ripple current specifications given for low (120 Hz) and high (50 kHz) frequency conditions support selection for a range of switching and mains‑related environments.
• RoHS Compliance: Material compliance supports regulatory requirements for lead‑free assemblies.
• Series Safety Design: LAR series features include reduced short incidence under 1.5× rated overvoltage conditions, contributing to safer overvoltage behavior as defined by series testing.
