LLS2Z331MELY

The LLS2Z331MELY is a snap-in, radial can aluminum electrolytic capacitor offering 330 µF capacitance at a 180 V rated voltage. Designed for general-purpose applications, it combines a compact φ20 × 30 mm form factor with robust ripple-current capability and long endurance for reliable power-conditioning and energy-storage functions.

With an operating temperature range of −40 °C to 85 °C and endurance specified for 3000 hours at 85 °C under rated ripple current, this part addresses applications requiring sustained performance under continuous load.

Key Features

• Capacitance & Tolerance — 330 µF nominal with tolerance −20% to +20% (measured at 120 Hz, 20 °C), providing defined energy-storage for DC-link and smoothing tasks.
• Rated Voltage — 180 V working voltage for medium-voltage applications that require higher voltage headroom.
• Snap-In Radial Can Package — Snap-in terminal, radial can (φ20 × 30 mm) for secure PCB mounting and mechanical stability in assembled power modules.
• High Ripple-Current Capability — Low-frequency ripple current of 1.77 A at 120 Hz and high-frequency ripple current of 2.655 A at 50 kHz, supporting designs with significant AC ripple components.
• Endurance — Rated for 3000 hours at 85 °C with specified limits on capacitance change, tan δ, and leakage current after endurance testing.
• Low Losses — Tangent of loss angle (tan δ) of 0.15 measured at 20 °C, 120 Hz, for predictable dissipation characteristics.
• Leakage Current — Specified leakage current (730 µA) to aid in system-level current budgeting and standby-loss calculations.
• Wide Temperature Range — Operates from −40 °C to 85 °C to accommodate a broad range of ambient conditions.
• RoHS Compliant — Meets RoHS requirements for restricted substances in electronic components.

Typical Applications

• General-purpose power systems — Suitable for designs requiring 330 µF at 180 V where reliable energy storage and smoothing are needed under continuous ripple stress.
• PCB-mounted power assemblies — Snap-in radial can format enables straightforward insertion and secure mounting in power-supply assemblies and modules.
• High-ripple environments — High specified ripple-current ratings at both low and high frequencies make this capacitor appropriate where AC ripple tolerance is required over long durations.

Unique Advantages

• Proven endurance under continuous load — 3000 hours at 85 °C endurance rating ensures sustained performance when subjected to rated ripple current.
• Dual-frequency ripple support — Explicit ripple-current specifications at 120 Hz and 50 kHz help designers manage thermal and life considerations across switching and line-frequency regimes.
• Compact, serviceable package — φ20 × 30 mm snap-in can provides a small footprint while offering robust mechanical retention on PCBs.
• Predictable electrical characteristics — Specified tan δ and leakage current figures enable accurate loss and standby current estimations for system design.
• Broad operating temperature — −40 °C to 85 °C rating supports deployment in environments with variable ambient conditions.
• RoHS compliance — Facilitates regulatory alignment for assemblies targeting restricted-substance requirements.
