LAR2W121MELZ35

The LAR2W121MELZ35 is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose higher‑voltage applications. It provides a 450 V rated voltage with 120 µF capacitance, ±20% tolerance, polarized construction and a radial can snap‑in package.

Engineered for durability in elevated temperatures, this capacitor is specified for operation up to 105°C and is capable of withstanding 2000 hours of rated ripple current at 105°C, making it suitable for designs that demand sustained ripple performance and robust mounting.

Key Features

• Rated Performance — 450 V nominal voltage and 120 µF capacitance with ±20% tolerance, providing defined high‑voltage energy storage in a single component.
• High‑temperature Endurance — Specified for operation from −25°C to +105°C with an endurance rating of 2000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current specifications include 720 mA at 120 Hz and 1.03 A at 50 kHz; frequency coefficients in the datasheet allow designers to scale ripple limits by frequency.
• Safety Performance under Overvoltage — Designed to reduce incidence of shorting when subjected to overvoltage conditions (rated voltage × 1.5); series tests show passing behavior under limited‑current overvoltage conditions.
• Robust Mounting — Snap‑in terminal radial can package provides secure chassis or PCB mounting for through‑hole power assemblies.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Physical Dimensions — Compact radial can: approximately 3.5 cm length × 2.2 cm diameter; max seated height 1.378 in (specified dimensioning supports mechanical planning).

Typical Applications

• General purpose high‑voltage power systems — Provides bulk energy storage and DC link capacitance where a 450 V rated, polarized electrolytic is required.
• High‑temperature environments — Suited to assemblies that must maintain capacitance and leakage performance up to 105°C for extended periods (2000 h endurance).
• Through‑hole power modules and chassis‑mounted assemblies — Snap‑in radial can package simplifies secure mounting in power conversion and industrial equipment.

Unique Advantages

• High voltage capability: 450 V rating enables use in higher‑voltage DC circuits without series stacking.
• Long ripple‑rated life at elevated temperature: 2000 hours at 105°C with rated ripple current provides predictable long‑term performance under stress.
• Measured ripple specifications: Published ripple current values at 120 Hz and 50 kHz allow accurate thermal and reliability margining in design.
• Reduced short incidence under overvoltage: Series safety performance targets reduced shorting when exposed to 1.5× rated voltage under limited current conditions, aiding system safety planning.
• Secure snap‑in mounting: Radial, snap‑in can form factor minimizes mechanical stress on solder joints and supports robust assembly techniques.
• Regulatory compliance: RoHS conformity supports designs targeting regulated global markets.
