LGU2Z821MELZ

The LGU2Z821MELZ is an aluminum electrolytic, snap‑in terminal capacitor designed for general‑purpose electronic applications. It delivers 820 µF at a rated voltage of 180 V in a radial can with snap‑in mounting, and is polarized for conventional electrolytic capacitor use.

Engineered for extended operation at elevated temperature, this part withstands 3000 hours of rated ripple current application at 105°C and is RoHS compliant, making it suitable where stable high‑temperature performance and regulatory compliance are required.

Key Features

• Capacitance and Voltage — 820 µF nominal capacitance with a 180 V rated voltage; capacitance tolerance ±20% (measured at 120 Hz, 20°C).
• High‑temperature Endurance — Endurance specification: able to withstand 3000 hours of D.C. bias plus rated ripple current at 105°C with capacitance change within ±20% and leakage current within initial specified limits.
• Ripple Current Capability — Rated ripple current of 2.04 A at 120 Hz and 3.06 A at 50 kHz, supporting AC ripple handling at those frequencies.
• Operating Temperature Range — Specified for −40°C to +105°C operation (for the applicable rated voltages), enabling use across a wide thermal range.
• Electrical Loss and Stability — Applicable tan δ limit for the 160–420 V range is 0.15 (measurement at 120 Hz, 20°C); low‑temperature impedance characteristics are specified for the 160–250 V range (Z(−25°C)/Z(+20°C) ≤ 3, Z(−40°C)/Z(+20°C) ≤ 12).
• Leakage Current — Leakage current meets I ≤ 3CV (µA) after 5 minutes application of rated voltage at 20°C, per the series specification.
• Mechanical & Mounting — Radial, can‑style snap‑in package (L: 5 × D: 2.2 cm) with snap‑in terminals for robust board attachment and straightforward assembly; maximum seated height is 1.969 inch.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose electronic equipment — Suitable where a polarized aluminum electrolytic capacitor with 180 V rating and 820 µF capacitance is required for board‑level energy storage.
• Printed circuit boards with snap‑in assembly — Snap‑in terminals provide secure mechanical retention for applications that favor radial can mounting and easy insertion.
• High‑temperature operating environments — Designed for continuous operation up to 105°C and endurance testing of 3000 hours at that temperature when subjected to rated ripple current.

Unique Advantages

• Long high‑temperature life: The 3000‑hour endurance at 105°C provides predictable performance over extended elevated‑temperature operation, supporting reliability targets.
• Defined ripple handling: Specified ripple current values at 120 Hz and 50 kHz enable selection based on expected ripple frequency and magnitude.
• Compact radial can footprint: 5 × 2.2 cm package offers substantial capacitance (820 µF) in a compact snap‑in can suitable for dense board layouts.
• Clear electrical limits: Tangent of loss angle (tan δ), leakage current formula, and low‑temperature impedance ratios are specified for design verification and margining.
• RoHS compliant: Meets RoHS directive requirements for materials compliance in regulated markets.
