LLG2W151MELZ30

The LLG2W151MELZ30 is an aluminum electrolytic, snap-in terminal capacitor from Nichicon's LLG series. It provides 150 µF capacitance at a 450 V rated voltage in a radial, snap-in can designed for general-purpose use.

Part of the LLG family, this device is one rank smaller in case size than the LLS series and is suited for equipment downsizing while remaining RoHS compliant.

Key Features

• Capacitance & Rated Voltage — 150 µF nominal capacitance with a 450 V rated voltage and tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• Package & Mounting — Radial, can-type snap-in terminal for secure, board-mounted installation and simplified assembly.
• Compact Dimensions — Physical size approximately L: 3.0 cm × D: 2.2 cm with a maximum seated height of 1.181 inch, offering a smaller-case option compared to LLS.
• Operating Temperature & Lifetime — Rated for operation from −25°C to +85°C with an expected endurance of 2000 hours at 85°C under the series endurance test conditions.
• Ripple Current Performance — Rated ripple current of 1.04 A at 120 Hz and 1.487 A at 100 kHz to support DC bias plus rated ripple conditions.
• Leakage Current Specification — Leakage current conforms to the series formula I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20°C.
• Tangent of Loss Angle (tan δ) — Specified tan δ maximum 0.20 at the 450 V rating (measurement at 120 Hz, 20°C).
• Low‑Temperature Stability — For 400–450 V ratings, the impedance ratio Z(–25°C)/Z(+20°C) is specified up to 8 (measurement at 120 Hz).
• RoHS Compliance — Manufactured in accordance with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose high-voltage filtering — Smoothing and bulk energy storage in equipment that requires 450 V ratings and 150 µF capacitance.
• Space-constrained equipment — One rank smaller case than LLS, useful where board space and overall component height must be reduced.
• High-voltage power modules — Provides rated ripple handling and 2000-hour endurance at 85°C for use in industrial power assemblies and other high-voltage subsystems.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage circuits without changing component family.
• Compact form factor: Smaller case size than LLS supports equipment downsizing and tighter packing on PCBs.
• Snap-in mounting: Radial snap-in terminals simplify installation and provide robust board retention for larger can-style capacitors.
• Documented endurance: 2000 hours at 85°C performance criteria—capacitance change, tan δ and leakage current limits—provide predictable in‑service behavior.
• Measurable ripple specifications: Specified ripple currents at 120 Hz and 100 kHz allow designers to assess thermal and ripple-handling requirements explicitly.
• RoHS compliance: Meets current RoHS directives for regulatory acceptance in many markets.

Why Choose LLG2W151MELZ30?

The LLG2W151MELZ30 combines a 450 V rating with 150 µF capacitance in a snap-in aluminum electrolytic package that is intentionally smaller than the LLS family to support equipment downsizing. Its documented endurance at 85°C, specified ripple currents, and leakage current formula make performance predictable for high-voltage, general-purpose designs.

This part is suitable for design teams and purchasers looking for a compact, RoHS-compliant electrolytic capacitor with clear electrical and thermal limits, particularly where board real estate and reliable high-voltage operation are priorities.
