LAR2W101MELZ30

The LAR2W101MELZ30 is a Nichicon aluminum electrolytic capacitor in a snap‑in terminal radial can package. It is a polarized, high‑voltage capacitor rated at 450 V with 100 µF capacitance and ±20% tolerance, designed for general‑purpose applications that require sustained performance at elevated temperatures.

Engineered for robust ripple endurance and thermal stability, this part is specified for operation from −25°C to 105°C and meets long‑term endurance requirements under rated ripple current at 105°C.

Key Features

• High voltage rating (450 V) — Suitable for circuits that require 450 V working voltage.
• 100 µF capacitance, ±20% tolerance — Provides bulk energy storage and smoothing with defined tolerance at 120 Hz, 20°C.
• Snap‑in radial can package — Snap‑in terminals enable secure mechanical mounting for chassis or PCB installation.
• Polarized design — Conventional electrolytic polarity for DC applications.
• Wide operating temperature — Rated for −25°C to 105°C, supporting higher‑temperature environments.
• 2000‑hour ripple endurance at 105°C — Specified to withstand 2000 hours of rated ripple current at 105°C with limits on capacitance change, tan δ and leakage current.
• High ripple current capability — Defined ripple current values: 690 mA at 120 Hz and 986.7 mA at 50 kHz; frequency coefficients for 400/450 V series are provided in the series datasheet to scale ripple with frequency.
• Safety performance under overvoltage — Series design reduces short incidence when subjected to 1.5× rated voltage (limited current condition) and meets the series safety criteria for vent operation or non‑opening for 10 minutes without short or flame.
• Electrical characteristics — Leakage current meets I ≤ 3√CV (µA) after 5 minutes at 20°C; tan δ max of 0.20 at 450 V (measured at 120 Hz, 20°C).
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power filtering & smoothing — Bulk smoothing and ripple filtering where a 450 V rating and robust ripple endurance are required.
• High‑voltage DC circuits — Energy storage and decoupling in circuits that operate at elevated DC voltages and temperatures.
• General‑purpose electronic equipment — Use in general purpose applications specified by the manufacturer for this series.

Unique Advantages

• Designed for elevated‑temperature endurance: 2000 hours at 105°C under rated ripple current provides predictable long‑term behavior in hot environments.
• Robust overvoltage behavior: Series safety performance reduces incidence of shorts when exposed to 1.5× rated voltage under limited current conditions, improving fault tolerance.
• High ripple capability across frequencies: Specified ripple currents with provided frequency coefficients allow designers to assess performance from low to high frequencies.
• Secure snap‑in mounting: Radial snap‑in can construction supports reliable mechanical retention for chassis or board installations.
• Clear electrical characterization: Leakage current and tan δ limits are defined for verification and quality control during design and production.
• RoHS compliance: Conforms to applicable RoHS directives for environmental compliance.
