LGU1H103MELC

The LGU1H103MELC is a Nichicon LGU series aluminum electrolytic capacitor in a snap‑in radial can package. It is a polarized, board‑mountable capacitor specified for general‑purpose applications and designed for extended high‑temperature operation up to 105°C.

Key value propositions include robust ripple current endurance at elevated temperature, verified long‑life performance under rated ripple and bias, and RoHS compliance for regulated applications.

Key Features

• Capacitance and Voltage — 10 mF nominal capacitance with a rated voltage of 50 V and a tolerance of −20% to +20%.
• High‑temperature rating — Rated for operation from −40°C to +105°C, supporting designs that require elevated operating temperatures.
• Snap‑in radial can package — Snap‑in mounting type in a radial can form factor (package case: radial, can - snap‑in) for secure board insertion and mechanical retention.
• Ripple current capability — Rated ripple current of 4.07 A at 120 Hz and 4.681 A at 50 kHz, enabling effective AC ripple handling in power circuits.
• Endurance at elevated temperature — Designed to withstand 3000 hours of rated ripple current application at 105°C; after the test, capacitance change remains within ±20% and leakage current remains at or below the initial specified value.
• Polarized construction — Polarized capacitor suitable for DC bias applications where polarity is observed.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Physical footprint — Compact dimensions: L: 4 × D: 3.5 cm, with a seated height specification provided (1.575 inch maximum) for board‑level planning.

Typical Applications

• General‑purpose power assemblies — Board‑mounted filtering and energy storage where a polarized snap‑in capacitor is required and elevated temperature endurance is needed.
• Industrial electronics — Use in assemblies that demand sustained ripple handling and long‑term stability at up to 105°C.
• Commercial power modules — Suitable for applications needing a compact radial can capacitor with defined ripple current ratings at both low and higher frequencies.

Unique Advantages

• Proven high‑temperature endurance: Withstanding 3000 hours of rated ripple current at 105°C provides predictable aging behavior and capacity retention for long‑life designs.
• Measured ripple performance: Explicit ripple current ratings (4.07 A at 120 Hz; 4.681 A at 50 kHz) allow designers to size the capacitor for specific AC conditions.
• Board retention and mechanical stability: Snap‑in radial can construction offers secure mounting for assemblies that undergo handling or vibration.
• Regulatory compliance: RoHS conformity supports deployment in regions and products requiring restricted‑substance compliance.
• Clear electrical limits: Specified tolerance, polarization, and operating temperature range simplify component selection and reliability planning.

Why Choose LGU1H103MELC?

LGU1H103MELC combines a high nominal capacitance (10 mF) and a 50 V rating in a snap‑in radial can engineered for sustained operation up to 105°C. Its defined ripple current ratings and documented 3000‑hour endurance under rated ripple and bias make it suitable for general‑purpose board‑level power applications that require predictable aging and leakage behavior.

This part is appropriate for designers and procurement teams specifying robust, RoHS‑compliant electrolytic capacitors for commercial and industrial assemblies where polarized, board‑mounted capacitors with clear performance data are required.
