LGW2G101MELZ25

The LGW2G101MELZ25 is a 100 µF, 400 V aluminum electrolytic capacitor in a snap‑in radial can package designed for general-purpose applications that require high ripple current capability and elevated operating temperature. It delivers sustained performance at up to 105°C and is specified to withstand 3000 hours of rated ripple current at that temperature.

Built for designers of power conversion and industrial electronics, this polarized snap‑in capacitor combines compact dimensions (L: 2.5 × D: 2.2 cm), RoHS compliance, and measurable ripple current ratings to support reliable DC‑link, filtering, and energy storage uses in high-voltage assemblies.

Key Features

• Capacitance & Rated Voltage: 100 µF nominal capacitance rated at 400 V DC for high-voltage designs.
• High Ripple Current Capability: Specified ripple current of 1.02 A at 120 Hz and 1.459 A at 50 kHz to support applications with significant AC ripple on DC rails.
• 105°C Endurance: Designed to withstand 3000 hours of rated ripple current at 105°C, with endurance criteria defined for capacitance, tan δ and leakage current after test.
• Operating Temperature Range: −25°C to +105°C suitable for elevated‑temperature environments encountered in power electronics.
• Package & Mounting: Snap‑in terminal, radial can package for secure PCB mounting and robust mechanical retention in high-current assemblies.
• Electrical Characteristics: Polarized construction with capacitance tolerance of −20% to +20% and leakage current defined by I ≤ 3√CV after 5 minutes at 20°C.
• Compliance: RoHS compliant (2011/65/EU, (EU)2015/863), meeting current environmental directives.

Typical Applications

• Power supplies and DC‑link circuits: High voltage rating and elevated ripple capability support smoothing and energy storage on DC rails in power converters.
• Industrial power conversion: Suitable for filter and bulk storage tasks in drives and inverters operating at elevated temperatures.
• High‑frequency switching systems: Rated ripple current at both low and high frequencies enables use where switching ripple and high‑frequency content are present.

Unique Advantages

• Rated for sustained high ripple: Explicit ripple current specifications at 120 Hz and 50 kHz provide measurable data for thermal and reliability assessments under AC stress.
• Endurance at elevated temperature: 3000 hours at 105°C with rated ripple current offers predictable long‑term behavior for thermal‑challenging designs.
• High voltage capability: 400 V rating allows integration into higher‑voltage power systems without additional series stacking.
• Secure PCB retention: Snap‑in radial can format provides mechanical stability in assemblies subjected to vibration or handling.
• Environmental compliance: RoHS conformity reduces regulatory risk for global product deployment.
