LGN2Z681MELY45

The LGN2Z681MELY45 is an aluminum electrolytic, snap‑in terminal capacitor designed for general‑purpose power applications that require high temperature endurance. It is part of Nichicon's LGN series and combines a 680 µF capacitance with a 180 V rated voltage in a compact snap‑in radial can package.

Key value propositions include sustained performance at elevated temperatures, rated ripple current capability across common frequencies, and RoHS compliance for regulatory alignment.

Key Features

• Capacitance and Voltage — 680 µF rated capacitance with a 180 V rated voltage and ±20% tolerance, suitable as bulk or smoothing capacitance in general‑purpose circuits.
• High‑temperature Endurance — Specified to withstand 3000 hours of rated ripple current at 105°C, maintaining capacitance, tan δ, and leakage within endurance limits after stress.
• Operating Temperature Range — Rated for operation from −40°C to +105°C, supporting applications with elevated ambient temperatures.
• Rated Ripple Current — 1.7 A at 120 Hz and 2.55 A at 100 kHz, providing defined AC stress handling for filtering and power decoupling tasks.
• Mounting and Package — Snap‑in terminal, radial can (snap‑in) package for secure mechanical retention and through‑hole assembly.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), meeting common hazardous‑substance requirements.

Typical Applications

• General‑purpose power circuitry — Bulk capacitance and smoothing in power supply stages where polarized electrolytic capacitors are required.
• High‑temperature equipment — Circuits that must sustain rated ripple and capacitance at operating temperatures up to 105°C.
• Through‑hole / snap‑in assemblies — Systems designed for snap‑in radial can components requiring reliable mechanical retention.

Unique Advantages

• Extended elevated‑temperature life — 3000‑hour endurance at 105°C under rated ripple current supports longer service intervals in hot environments.
• Defined ripple performance — Specified ripple current values at both 120 Hz and 100 kHz enable predictable thermal and electrical behavior under AC loading.
• Compact snap‑in form — Smaller‑sized case (one rank smaller than LGU) and radial snap‑in package help optimize board space and assembly robustness.
• Clear electrical specifications — 680 µF, 180 V, ±20% tolerance and polarized construction simplify component selection for DC power applications.
• Regulatory alignment — RoHS compliance reduces material‑related integration concerns for regulated markets.
