LAR2W820MELZ25

The LAR2W820MELZ25 is a snap‑in terminal aluminum electrolytic capacitor rated 450V with 82µF capacitance in a compact radial can package. Designed for general‑purpose high‑voltage applications, it combines a high voltage rating, snap‑in mounting and extended endurance for robust performance in power circuits.

Key value propositions include guaranteed 2000 hours of rated ripple current endurance at 105°C, built‑in safety behavior under overvoltage conditions, and RoHS compliance for environmentally conscious designs.

Key Features

• High Voltage, Defined Capacitance — 450V rated voltage with 82 µF capacitance, polarized construction suitable for high‑voltage smoothing and energy storage where a compact radial can is required.
• Snap‑In Package — Radial, can style with snap‑in terminals for secure mechanical mounting and straightforward assembly into power assemblies.
• Thermal Endurance — Withstands 2000 hours of rated ripple current application at 105°C, providing predictable life under elevated operating temperatures.
• Ripple Current Ratings — Specified ripple current of 340 mA at 120 Hz and 486.2 mA at 50 kHz, with frequency coefficients available for other operating frequencies.
• Safety under Overvoltage — Designed to reduce incidence of shorting when exposed to overvoltage (rated voltage × 1.5); datasheet safety testing shows performance under 1 A limited current conditions with defined venting behavior.
• Electrical Characteristics — Capacitance tolerance ±20% (120 Hz, 20°C); leakage current specified as I ≤ 3√CV (µA) after 5 minutes at 20°C; tangent of loss angle (tan δ) max 0.20 for 450V units.
• Low‑Temperature Stability — Impedance stability characterized for high‑voltage types: Z(−25°C)/Z(+20°C) up to 8 for 400–450V ratings.
• Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Circuits — Suitable where a 450V polarized capacitor is required for filtering, smoothing or bulk energy storage in high‑voltage assemblies categorized as general‑purpose.
• High‑Voltage Filtering — Used to manage ripple current and stabilize DC rails when a compact, snap‑in radial can solution is preferred.
• Industrial Power Electronics — Applicable in industrial modules that require rated performance at elevated temperatures up to 105°C with defined ripple endurance.

Unique Advantages

• High Voltage Capability: 450V rating enables use in higher‑voltage DC circuits without series stacking.
• Proven Endurance: 2000 hours at 105°C under rated ripple current gives predictable life for thermal and ripple‑stress environments.
• Snap‑In Reliability: Snap‑in terminals provide secure mechanical fixation for robust assembly in power enclosures.
• Built‑In Overvoltage Safety: Designed to reduce short incidence under rated voltage × 1.5 and tested for controlled venting behavior under limited‑current overvoltage conditions.
• Measurable Electrical Limits: Clear specifications for leakage current (I ≤ 3√CV), tan δ (max 0.20 at 450V), and frequency‑dependent ripple capabilities aid accurate design margining.
• RoHS Compliant: Meets RoHS directive requirements for environmentally regulated markets.
