LGU1C103MELZ

The LGU1C103MELZ is an aluminum electrolytic capacitor in a snap-in terminal configuration designed for general-purpose power applications. It is specified for operation from –40°C to 105°C and is built to withstand extended ripple-current stress.

Key design benefits include a 10 mF capacitance at 16 V rating, 3000 hours endurance under rated ripple current at 105°C, and RoHS compliance, delivering reliable bulk capacitance and smoothing in demanding thermal environments.

Key Features

• Capacitance & Voltage — 10 mF capacitance with a 16 V rated voltage and ±20% tolerance, suitable for bulk energy storage and smoothing in DC power circuits.
• High Temperature Endurance — Rated for operation up to 105°C with a guaranteed 3000 hours of endurance when subjected to D.C. bias plus rated ripple current at 105°C.
• Ripple Current Performance — Supports 2.1 A ripple current at 120 Hz and 2.415 A at 50 kHz, enabling effective filtering where continuous ripple-handling is required.
• Mounting & Package — Snap-in terminal, radial can package designed for secure board retention and high-current power applications.
• Wide Operating Range — Specified for use from –40°C to 105°C, supporting operation in elevated ambient temperatures.
• Environmental Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
• Polarized Design — Polarized capacitor for use in DC circuits where correct polarity is maintained.
• Compact Footprint — Physical size L: 3 × D: 2.2 cm, enabling use in space-conscious power assemblies.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and smoothing in DC power rails, utilizing its 10 mF value and rated ripple-current capability for effective voltage stabilization.
• Power supply bulk storage — Stores energy and attenuates ripple in power supply outputs where elevated operating temperature up to 105°C is expected.
• Industrial electronics — Suited for general-purpose industrial modules that require polarized bulk capacitance with long ripple endurance at elevated temperatures.

Unique Advantages

• Long ripple-life specification — 3000 hours endurance at 105°C under rated ripple current provides predictable aging behavior for design planning.
• Measured ripple handling — Published ripple current values at both low (120 Hz) and high (50 kHz) frequencies help match the capacitor to converter and filter requirements.
• Snap-in retention — Snap-in terminal and radial can packaging ensure secure mounting and good mechanical stability in power assemblies.
• Wide temperature capability — Operation from –40°C to 105°C supports deployment in elevated-temperature environments without derating the core endurance claim.
• Regulatory compliance — RoHS compliance supports use in designs targeting global environmental requirements.
