LLS1K182MELZ

The LLS1K182MELZ is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It combines an 80 V rated voltage with 1.8 mF capacitance in a radial can with snap‑in mounting for secure PCB retention and high ripple handling.

Built to withstand continuous ripple stress, this series offers endurance at elevated temperature and is RoHS compliant, making it suitable for industrial and power‑supply environments where long life and reliable decoupling are required.

Key Features

• Capacitance and Voltage — 1.8 mF capacitance at a rated voltage of 80 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• Snap‑In Radial Package — Snap‑in terminal, radial can package for robust PCB mounting and easy assembly.
• Operating Temperature — Rated for –40 °C to 85 °C operation, supporting a wide range of ambient conditions.
• Endurance at Elevated Temperature — Specified to withstand 3000 hours of rated ripple current at 85 °C, with capacitance change within ±20% and leakage within initial specified limits after test.
• Ripple Current Capability — Rated ripple current of 2.11 A at 120 Hz and 2.426 A at 50 kHz, enabling effective smoothing and energy buffering in power circuits.
• Leakage Current Specification — Leakage current defined as I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20 °C, allowing predictable bias performance.
• Loss Tangent (tan δ) — Maximum tan δ of 0.20 at the 80 V rating (measured at 120 Hz, 20 °C), useful for assessing ESR‑related heating and losses.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements.
• Compact Mechanical Size — Physical footprint approximately L: 3 cm × D: 2.2 cm with snap‑in terminals for space‑efficient power designs.

Typical Applications

• Switch‑mode Power Supplies — Bulk filtering and output smoothing where 80 V rating and high ripple endurance improve stability and lifetime.
• Industrial Power Electronics — Energy buffering and decoupling in motor drives, inverters, and control systems operating within –40 °C to 85 °C.
• Instrumentation and Control — Local supply stabilization and transient absorption for reliable sensor and control circuitry operation.

Unique Advantages

• Designed for Extended Ripple Stress — Rated to endure 3000 hours at 85 °C under rated ripple current, providing predictable life under continuous load.
• Clear Electrical Limits — Published ripple current values at 120 Hz and 50 kHz and a defined leakage current formula help engineers size thermal and reliability margins.
• Temperature Performance Data — Specified impedance ratios at low temperatures (e.g., Z(–25 °C)/Z(+20 °C) and Z(–40 °C)/Z(+20 °C) ranges in the datasheet) support designs across cold and warm environments.
• Robust Mounting — Snap‑in terminals provide secure mechanical retention for high‑vibration or high‑current board applications.
• Regulatory Compliance — RoHS compliance simplifies material conformity for commercial and industrial product lines.
