LGZ2W181MELB45

The LGZ2W181MELB45 is a snap‑in terminal type aluminum electrolytic capacitor offering 180 µF capacitance at a 450 V rating. It is built for general‑purpose applications that require high‑voltage capacitance with long operational life and RoHS compliance.

Designed for durable performance, this radial can (snap‑in) capacitor delivers 20,000 hours of endurance at 105°C and supports a wide operating temperature range from −25°C to +105°C.

Key Features

• Capacitance & Voltage — 180 µF rated capacitance with a 450 V nominal voltage to support high‑voltage general‑purpose circuits.
• High‑temperature Long Life — Endurance specified as 20,000 hours at 105°C when subjected to DC bias plus rated ripple current; capacitance change within ±25% after the endurance test.
• Temperature Range & Low‑temperature Stability — Operating range −25°C to +105°C with an impedance ratio Z(−25°C)/Z(+20°C) up to 8 (measured at 120 Hz), ensuring predictable behavior across temperature extremes.
• Ripple Current Capability — Rated ripple of 870 mA at 120 Hz; frequency response allows higher ripple at elevated frequencies (e.g., ~1.244 A at 50 kHz as specified for high‑frequency conditions).
• Leakage Current & Loss — Leakage current specified by I ≤ 3√(C·V) µA after 5 minutes at 20°C; tangent of loss angle (tan δ) max 0.20 at 120 Hz and 20°C.
• Package & Mounting — Radial can, snap‑in terminal style for secure board retention and robust mechanical mounting.
• Tolerance & Polarity — Capacitance tolerance ±20% (at 120 Hz, 20°C); polarized device requiring correct polarity in application.
• RoHS Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Form Factor — Compact body size 30 × 45 mm (φD × L) for board‑level integration in equipment with snap‑in mounting.

Typical Applications

• Power Supplies — Provides high‑voltage capacitance for general‑purpose power supply designs where long operational life at elevated temperature is required.
• Industrial Power Systems — Suited for general‑purpose industrial equipment that requires reliable bulk capacitance and high ripple handling over extended duty cycles.
• Energy Storage & Filtering — Used in general‑purpose circuits requiring energy storage and ripple current handling at high DC voltages and elevated temperatures.

Unique Advantages

• Proven long life: Specified endurance of 20,000 hours at 105°C provides predictable aging and lifecycle planning for designs operating at high temperature.
• High voltage capability: 450 V rating enables use in higher‑voltage general‑purpose power and industrial circuits without additional series stacking.
• Robust ripple handling: Rated ripple current of 870 mA at 120 Hz and higher allowable ripple at elevated frequencies supports demanding ripple conditions.
• Temperature stability: Wide −25°C to +105°C operating range and defined impedance behavior at low temperature (Z(−25°C)/Z(+20°C) = 8) help maintain performance across environments.
• Defined electrical limits: Leakage current and tan δ specifications (I ≤ 3√CV µA; tan δ ≤ 0.20 at 120 Hz) make it straightforward to model and verify in designs.
• RoHS compliant package: Meets applicable RoHS directives for materials compliance in modern electronic assemblies.
