LLS2A182MELZ

The LLS2A182MELZ is an aluminum electrolytic, snap‑in terminal capacitor designed for general‑purpose power applications. It is an 85°C standard snap‑in can that delivers 1.8 mF capacitance at a 100 V rating and is RoHS compliant.

Engineered for sustained ripple duty, this part is specified to withstand 3000 hours of rated ripple current at 85°C, making it suitable for demanding filtering and smoothing roles in industrial and power electronics systems.

Key Features

• Capacitance & Voltage 1.8 mF nominal capacitance with a 100 V rated voltage and a capacitance tolerance of ±20% (120 Hz, 20°C).
• Snap‑in, Radial Can Package Snap‑in terminal, radial can package for robust board mounting; physical size L: 4 × D: 2.2 cm and maximum seated height 1.575 inch.
• Ripple Current Capability Rated ripple current of 2.77 A at 120 Hz and 3.186 A at 50 kHz, enabling reliable AC ripple handling across common power frequencies.
• Endurance at Elevated Temperature Designed to meet specified performance after 3000 hours of DC bias plus rated ripple at 85°C; capacitance change within ±20% post‑test, tan δ remains ≤200% of initial spec, and leakage current remains at or below initial specification.
• Operating Temperature Range −40°C to +85°C, supporting a wide range of ambient conditions for general‑purpose applications.
• Leakage Current Specification Leakage current specified as I ≤ 3√(C·V) μA after 5 minutes at 20°C, providing a clear, measurable leakage limit for design verification.
• Dielectric Loss (tan δ) Maximum tan δ for the 100 V rating is 0.20 (measured at 120 Hz, 20°C), indicating predictable dielectric loss characteristics.
• Low‑Temperature Impedance Stability For rated voltages 16 V to 100 V: Z(−25°C)/Z(+20°C) ≤ 4 and Z(−40°C)/Z(+20°C) ≤ 20, aiding performance estimation in cold environments.
• RoHS Compliant Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies Bulk smoothing and ripple suppression in AC/DC and DC/DC power supplies, leveraging the part's high ripple current rating and 100 V voltage rating.
• Industrial Power Modules Energy filtering and decoupling in motor drives and industrial converters where long endurance at elevated temperature is required.
• Power Conditioning Use in power filtering stages to stabilize DC rails and reduce voltage ripple over long operational periods at up to 85°C.

Unique Advantages

• Proven Ripple Endurance Rated to withstand 3000 hours of rated ripple current at 85°C, providing designers with a clear endurance benchmark for long‑term performance.
• High Ripple Capability Across Frequencies Specified ripple current values at both 120 Hz and 50 kHz support designs that encounter a range of switching and line frequencies.
• Clear, Measurable Leakage Limit Leakage current defined by I ≤ 3√(C·V) μA (after 5 minutes at 20°C) enables straightforward validation during incoming inspection and qualification testing.
• Predictable Loss and Low‑Temp Behavior Published tan δ and impedance ratios for low temperatures allow more accurate modeling of ESR and losses across operating conditions.
• Robust Mounting Snap‑in radial can construction simplifies secure board attachment for higher‑current or vibration‑prone environments.
• Regulatory Compliance RoHS compliance supports environmentally conscious product designs and regulatory requirements.
