LGU1V103MELB

The LGU1V103MELB is an aluminum electrolytic capacitor in Nichicon’s LGU series featuring a snap‑in terminal radial can design. It is a polarized, general‑purpose capacitor specified for operation from −40°C to 105°C and is built to withstand extended ripple current stress at elevated temperature.

Engineered for applications that need 10 mF capacitance at 35 V, this part delivers long endurance with a rated 3000‑hour life under rated ripple current at 105°C and meets RoHS requirements for environmental compliance.

Key Features

• Electrical Characteristics — 10 mF nominal capacitance at 35 V with ±20% tolerance; polarized design suitable for DC circuits.
• High‑temperature Endurance — Specified to withstand 3000 hours of rated ripple current at 105°C, with endurance criteria including capacitance change within ±20% and leakage current remaining within initial specified limits after test.
• Ripple Current Performance — Rated ripple current of 3.05 A at 120 Hz and 3.507 A at 50 kHz, enabling sustained AC stress handling in operating environments up to 105°C.
• Loss and Leakage — Tangent of loss angle (tan δ) is specified (max. 0.35 at 35 V, measured at 120 Hz, 20°C); leakage current follows datasheet limits (I ≤ 3CV (μA) after 5 minutes at 20°C).
• Mechanical & Mounting — Radial, snap‑in can package with snap‑in terminals for secure PCB installation; physical footprint: length 3.5 cm × diameter 3.0 cm.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose — Circuits requiring a 10 mF, 35 V polarized capacitor that can operate across −40°C to 105°C while providing bulk capacitance.
• High‑stress Power Assemblies — Designs that must tolerate sustained ripple current (3.05 A at 120 Hz; 3.507 A at 50 kHz) and require a component rated for 3000 hours at 105°C.
• PCB Installations with Robust Mounting — Applications that benefit from a radial snap‑in can for secure mechanical retention on the board and straightforward assembly.

Unique Advantages

• Long high‑temperature life: 3000 hours at 105°C under rated ripple conditions provides predictable endurance for prolonged elevated‑temperature operation.
• Defined ripple capability: Published ripple current ratings at 120 Hz and 50 kHz allow designers to size capacitors for steady AC loading with quantified margins.
• Clear electrical limits: Specified tan δ and leakage current criteria (I ≤ 3CV) give measurable parameters for loss and standby leakage during design verification.
• Secure mechanical interface: Snap‑in terminal radial can simplifies board mounting and improves retention in assembled systems.
• Regulatory compliance: RoHS compliance supports use in regions requiring restriction of hazardous substances.
