LLS1H682MELZ

The LLS1H682MELZ is an aluminum electrolytic capacitor in a snap‑in terminal, radial can package designed for 85°C standard operation. It delivers 6.8 mF capacitance at a 50 V rated voltage with polarized construction and snap‑in mounting for secure board attachment.

Targeted for general‑purpose electronic designs, this capacitor emphasizes long endurance under ripple load and complies with RoHS. Key performance attributes include rated ripple‑current capability at multiple frequencies and a specified 3000‑hour endurance at 85°C under rated ripple conditions.

Key Features

• Capacitance & Tolerance — 6.8 mF nominal capacitance with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 50 V DC rating suitable for medium‑voltage power circuits.
• Ripple‑current Performance — Specified ripple currents of 3.94 A at 120 Hz and 4.531 A at 50 kHz, with endurance testing supporting 3000 hours at 85°C under rated ripple current.
• Temperature Range & Endurance — Operating temperature range −40°C to +85°C and validated endurance after 3000 hours at 85°C with D.C. bias plus rated ripple current.
• Package & Mounting — Radial, can‑type construction with snap‑in terminals for robust mechanical retention on power boards.
• Leakage Current Specification — Series leakage current defined by I ≤ 3√CV (μA) after 5 minutes at 20°C, providing predictable initial leakage performance.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Physical Size — Dimensions: length 5 cm × diameter 2.2 cm, facilitating layout planning for radial snap‑in can components.

Typical Applications

• General‑Purpose Electronic Equipment — Provides bulk capacitance for board‑level designs that require a 6.8 mF, 50 V polarized capacitor with snap‑in mounting.
• Power Module Assemblies — Used where sustained ripple current and high‑temperature endurance (3000 h at 85°C) are required for reliable power conditioning.
• Industrial and Stationary Systems — Suitable for general‑purpose roles in stationary electronics that operate within −40°C to +85°C and require RoHS compliance.

Unique Advantages

• Proven ripple endurance: Endurance validated for 3000 hours at 85°C under rated ripple current, supporting long service life in ripple‑heavy applications.
• Dual‑frequency ripple ratings: Explicit ripple‑current specifications at 120 Hz and 50 kHz allow clearer design margins across common operating frequencies.
• Secure snap‑in mounting: Radial snap‑in terminals provide strong mechanical retention for board‑level power components.
• Predictable leakage behavior: Leakage current limit expressed as I ≤ 3√CV (μA) after 5 minutes at 20°C gives a measurable basis for initial leakage expectations.
• Regulatory compliance: RoHS conformity supports deployment in markets requiring restricted‑substance compliance.
