LLS1E123MELZ

The LLS1E123MELZ is a polarized aluminum electrolytic capacitor in a snap‑in radial can package designed for general‑purpose electronics. It provides 12 mF capacitance at a 25 V rating with a ±20% tolerance (measured at 120 Hz, 20°C).

Engineered for sustained ripple handling, this part is specified to withstand 3000 hours of rated ripple current at 85°C and is RoHS compliant (2011/65/EU, (EU)2015/863), making it suitable for designs requiring measurable endurance and environmental compliance.

Key Features

• Capacitance & Voltage — 12 mF rated capacitance at 25 V with ±20% tolerance (120 Hz, 20°C).
• Snap‑in Radial Can — Snap‑in terminal type in a radial, can-style package for secure mounting and straightforward assembly.
• Endurance at Elevated Temperature — Specified to withstand 3000 hours of rated ripple current at 85°C, supporting long-term operation under sustained ripple stress.
• Ripple Current Ratings — Rated ripple current: 3.77 A at 120 Hz and 4.335 A at 50 kHz, enabling designers to size for both low- and higher-frequency ripple conditions.
• Operating Temperature Range — −40°C to +85°C, suitable for a broad range of ambient conditions.
• Leakage and Dissipation — Leakage current specified as I ≤ 3√CV (μA) after 5 minutes at 20°C; tan δ (loss tangent) max 0.40 at 25 V (120 Hz, 20°C).
• Polarized, General‑Purpose — Polarized aluminum electrolytic intended for general-purpose applications requiring bulk capacitance.
• Physical Size — Compact footprint with dimensions L: 4 × D: 2.2 cm for layout and enclosure planning.
• Environmental Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑Purpose Power Systems — Provides bulk capacitance and rated ripple handling for smoothing and energy storage in power circuits where a 12 mF/25 V polarized capacitor is specified.
• Industrial Electronics — Suitable for designs that require defined ripple endurance and stable performance across −40°C to +85°C.
• Consumer and Commercial Equipment — Fits applications that benefit from a snap‑in radial can for reliable mounting and straightforward assembly.

Unique Advantages

• Quantified Ripple Endurance: 3000 hours at 85°C under rated ripple current gives predictable lifetime planning for sustained-stress applications.
• Dual-Frequency Ripple Specs: Explicit ripple current values at 120 Hz and 50 kHz allow accurate thermal and reliability calculations for both mains-frequency and higher-frequency circuits.
• Wide Ambient Range: −40°C to +85°C rating supports deployment across a broad set of environmental conditions.
• Measurable Electrical Limits: Leakage current and tan δ specifications provide concrete data for performance validation and acceptance testing.
• RoHS Compliance: Enables use in designs that require adherence to contemporary environmental directives.
