LGW2W101MELZ30

The LGW2W101MELZ30 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGW series, specified at 100 µF and 450 V. It is a polarized, radial can (snap-in) capacitor designed for general-purpose applications that require high ripple-current capability and long endurance at elevated temperature.

Key value propositions include high rated voltage, engineered ripple-current performance up to high frequencies, and proven endurance — withstanding 3000 hours at rated ripple current and 105°C — making it suitable where robust, high-voltage smoothing and energy-storage are required in general-purpose electronic assemblies.

Key Features

• Electrical Performance — 100 µF capacitance at 450 V rated voltage with ±20% tolerance (120 Hz, 20°C).
• High Ripple-Current Capability — Designed for high ripple current; rated ripple examples include 1.04 A at 120 Hz and 1.487 A at 50 kHz for this part.
• High-Temperature Endurance — Withstands 3000 hours of rated ripple current application at 105°C; post-test limits: capacitance change within ±20%, tan δ up to 200% of initial spec, leakage current ≤ initial spec.
• Operating Temperature Range — Specified for –25°C to +105°C at the 450 V rating.
• Leakage Current Specification — Leakage current meets I ≤ 3√(C·V) (µA) after 5 minutes at 20°C (C = μF, V = V).
• Frequency Coefficient for Rated Ripple — Ripple-current multipliers for 400–450 V range: 50 Hz = 0.77, 60 Hz = 0.82, 120 Hz = 1.00, 300 Hz = 1.16, 1 kHz = 1.30, 10 kHz = 1.41, ≥50 kHz = 1.43.
• Mechanical / Package — Radial, can-type with snap-in terminals; typical dimension L × D = 30 × 22 mm (height seated max 1.181 in).
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Electronics — Use where a polarized aluminum electrolytic capacitor with 450 V rating and high ripple capability is required for general-purpose circuit assemblies.
• High-Voltage Smoothing in General-Purpose Designs — Suitable for smoothing and decoupling roles in circuits operating up to 450 V where elevated operating temperature and sustained ripple are factors.
• Energy Storage in General-Purpose Modules — Acts as a bulk energy reservoir in assemblies that demand 100 µF at high DC voltage with reliable long-term performance at 105°C.

Unique Advantages

• Proven High-Ripple Endurance: Withstands 3000 hours of rated ripple current at 105°C, providing predictable long-term performance under sustained stress.
• High-Voltage Capability: 450 V rating enables use in higher-voltage general-purpose circuits while maintaining a compact footprint.
• Frequency-Aware Ripple Rating: Published frequency coefficients allow engineering adjustments to ripple limits across 50 Hz–50 kHz bands for accurate thermal/ripple design.
• Compact Snap-In Form Factor: Radial can with snap-in terminals delivers secure board mounting for through-hole assemblies and straightforward mechanical integration.
• Clear Reliability Limits: Endurance and shelf-life specifications (including post-test capacitance, tan δ, and leakage criteria) support predictable maintenance and replacement planning.
• RoHS Compliance: Conforms to applicable RoHS directives for regulatory alignment in general-purpose electronic products.
