LGU1E103MELZ

The LGU1E103MELZ is a Nichicon LGU series aluminum electrolytic capacitor in a snap‑in terminal radial can. It is a polarized, general‑purpose component specified at 10 mF and 25 V with an operating temperature range down to –40 °C and up to 105 °C.

Designed for applications that require sustained high‑temperature endurance and rated ripple‑current capability, this part withstands 3000 hours of rated ripple current at 105 °C and is RoHS compliant.

Key Features

• Capacitance & Voltage — 10 mF capacitance at a rated voltage of 25 V, suitable for bulk energy storage and smoothing in general‑purpose circuits.
• High‑temperature endurance — Endurance rating of 3000 hours at 105 °C when subjected to D.C. bias plus rated ripple current.
• Rated ripple current — 2.65 A at 120 Hz and 3.047 A at 50 kHz, supporting continuous ripple handling under specified conditions.
• Polarized, Snap‑in radial can — Snap‑in mounting type (radial, can) for secure board retention and straightforward assembly.
• Operating temperature range — –40 °C to 105 °C for 25 V devices, enabling use across a wide ambient temperature span.
• Tolerance — Capacitance tolerance of ±20% (–20% ~ +20%) at 120 Hz, 20 °C.
• Dielectric loss — tan δ (max) of 0.40 at 25 V (measured at 120 Hz, 20 °C) as specified for the LGU series.
• Physical dimensions — Length 4 × Diameter 2.2 cm; height seated maximum 1.575 inch (snap‑in radial can package).
• RoHS compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power circuits — Bulk filtering and smoothing in power supplies and converters where a 25 V, 10 mF polarized capacitor is required.
• High‑temperature environments — Circuits exposed to elevated operating temperatures up to 105 °C that require sustained ripple current endurance.
• Board‑mounted power modules — Snap‑in radial can style for secure mounting in power assemblies and industrial electronics.
