LLS1H392MELZ

The LLS1H392MELZ is an aluminum electrolytic capacitor in a snap‑in terminal, radial can package designed for general‑purpose power applications. It delivers 3.9 mF capacitance at a 50 V rating in a compact φ22 × 35 mm can with snap‑in mounting for secure board retention.

Engineered to operate across –40 °C to 85 °C with 3000 hours endurance at 85 °C under rated ripple, this part offers high ripple handling, controlled loss (tan δ), and RoHS compliance for reliable long‑life performance in industrial and commercial equipment.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) rated at 50 V with ±20% tolerance for bulk energy storage and decoupling where high capacitance is required.
• Snap‑in, Radial Can Package — Snap‑in terminal type in a radial can (φ22 × 35 mm) enabling secure mechanical retention for through‑hole assemblies.
• Operating Temperature & Endurance — Specified for –40 °C to 85 °C with a rated endurance of 3000 hours at 85 °C when subjected to DC bias plus rated ripple current.
• High Ripple Current Capability — Ripple current ratings of 2.72 A at 120 Hz and 3.128 A at 50 kHz support applications with significant AC stress.
• Electrical Reliability — Loss tangent tan δ of 0.30 (max) at 20 °C and 120 Hz, and a leakage current specified at 1320 µA, providing predictable electrical characteristics.
• Packaging & Compliance — Tray packed for mass production and compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Electronics — Suitable where a 3.9 mF, 50 V snap‑in capacitor is needed for bulk capacitance in power modules and assemblies.
• Industrial Equipment — Designed for extended operation at elevated ambient temperatures (up to 85 °C) and continuous ripple stress.
• Commercial Electronic Systems — Tray packing and snap‑in mounting make it convenient for high‑volume assembly and through‑hole board designs.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 2.72 A (120 Hz) and 3.128 A (50 kHz) allow handling of demanding AC components in power circuits.
• Proven endurance at elevated temperature: 3000 hours life at 85 °C under rated conditions provides long‑term stability for sustained thermal environments.
• Compact, robust mounting: Snap‑in radial can (φ22 × 35 mm) provides reliable mechanical retention for through‑hole assembly workflows.
• Predictable electrical behavior: Specified tan δ (0.30 at 20 °C/120 Hz) and defined leakage current (1320 µA) enable repeatable design margins.
• Production friendly packaging: Tray packing supports mass production handling and automated assembly processes.
• Regulatory compliance: RoHS compliant for use in regulated supply chains.
