LGN2Z821MELZ40

The LGN2Z821MELZ40 is an aluminum electrolytic capacitor in a snap‑in radial can intended for general‑purpose applications. It delivers 820 µF at 180 V in a compact, polarized snap‑in package and is specified for operation from −40 °C to +105 °C.

Designed to withstand 3,000 hours of rated ripple current at 105 °C and compliant with RoHS (2011/65/EU, (EU)2015/863), this part targets applications requiring durable high‑temperature ripple endurance with a reduced case size compared to the LGU series.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 180 V and ±20% tolerance at 120 Hz, 20 °C.
• High‑Temperature Endurance — Specified for −40 °C to +105 °C operating range and endurance of 3,000 hours at 105 °C under D.C. bias plus rated ripple current.
• Ripple Current Performance — Rated ripple current of 2 A at 120 Hz and 3 A at 100 kHz, supporting applications with sustained ripple loading.
• Snap‑In Radial Can Package — Snap‑in terminal type (radial, can - snap‑in) for secure board mounting and mechanical stability.
• Compact Footprint — Smaller‑sized case (one rank smaller than LGU) with dimensions approximately 4.0 cm × 2.2 cm, enabling tighter board layouts.
• Reliability Characteristics — Endurance and shelf‑life criteria: capacitance change within ±20%, tan δ ≤200% of initial spec, and leakage current less than or equal to initial specified value after endurance tests per datasheet.
• Environmental Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized Design — Polarized aluminum electrolytic construction for DC applications.

Typical Applications

• General‑Purpose Power Systems — Provides bulk energy storage and filtering in general‑purpose circuits requiring 820 µF at 180 V with snap‑in mounting.
• High‑Temperature Environments — Suitable for systems that require continuous operation up to 105 °C with proven 3,000‑hour ripple endurance.
• Board‑Level Snap‑In Installations — Snap‑in radial can package enables secure PCB mounting where robust mechanical retention is needed.
• High‑Ripple Current Circuits — Rated ripple currents of 2 A (120 Hz) and 3 A (100 kHz) support circuits with sustained ripple loading demands.

Unique Advantages

• Proven High‑Temperature Endurance: Rated for 3,000 hours at 105 °C under rated ripple current, providing predictable long‑term behavior in hot operating environments.
• Compact Case Size: One rank smaller than the LGU series, allowing designers to reduce board area without sacrificing capacitance or rated voltage.
• Dual‑Frequency Ripple Ratings: Explicit ripple current specifications at both 120 Hz and 100 kHz, enabling selection for varied switching and line‑frequency applications.
• Clear Reliability Limits: Endurance and shelf‑life specifications tied to measurable limits for capacitance change, tan δ, and leakage current simplify qualification and design validation.
• RoHS Compliance: Meets 2011/65/EU and (EU)2015/863 requirements for restricted substances.
• Polarized Snap‑In Form Factor: Polarized construction plus snap‑in terminals provide a robust, PCB‑friendly solution for DC bulk‑capacitance needs.
