LLS2E331MELA

The LLS2E331MELA is an aluminum electrolytic, snap-in terminal capacitor rated for 250 V and 330 µF with ±20% tolerance. It is designed for general-purpose applications that require through-hole snap-in mounting and dependable ripple-handling at both low and high frequencies.

Key value comes from its combination of rated voltage, ripple current capability, 3000-hour endurance at 85°C, and a compact φ25 × 25 mm can-style package suitable for tray packing and mass production.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a 250 V rated voltage with ±20% tolerance.
• Snap-in Terminal Package — Radial, can-type snap-in construction for secure through-hole mounting in tray-packed production quantities.
• Ripple Current Handling — 1.61 A at 120 Hz (low frequency) and 2.415 A at 50 kHz (high frequency) to support AC ripple and smoothing tasks.
• Low Dissipation Factor — tan δ of 0.15 (max) measured at 20°C and 120 Hz, indicating low ESR-related losses under specified conditions.
• Leakage Current — 860 µA specified initial leakage current for predictable standby characteristics.
• Endurance — Rated for 3000 hours at 85°C with performance criteria for capacitance change, tan δ, and leakage current as defined by endurance tests.
• Operating Temperature Range — −40°C to +85°C to cover a wide range of ambient conditions for general-purpose use.
• Form Factor — Compact φ25 × 25 mm can (L: 2.5 × D: 2.5 cm) for space-efficient board layouts.
• Compliance & Production — RoHS compliant and available in tray packing; listed as mass production status.

Typical Applications

• General-Purpose Electronics — Suitable where a 250 V, 330 µF electrolytic capacitor with snap-in mounting is required for board-level energy storage or decoupling.
• Power Supply Filtering — Used for smoothing and ripple reduction where the specified ripple current ratings (1.61 A at 120 Hz, 2.415 A at 50 kHz) are applicable.
• Industrial and Production Environments — Tray-packed, snap-in format supports high-volume assembly and repeated handling in mass production scenarios.

Unique Advantages

• High Working Voltage: 250 V rating enables applications that require elevated DC voltage handling compared with lower-voltage electrolytics.
• Robust Ripple Performance: Distinct low- and high-frequency ripple current ratings provide clear guidance for designers addressing AC ripple across frequency ranges.
• Long Endurance at Elevated Temperature: Specified 3000-hour life at 85°C offers measurable reliability for designs exposed to sustained thermal stress.
• Predictable Losses: Specified tan δ of 0.15 at 120 Hz and 20°C helps estimate ESR-related dissipation for thermal and efficiency calculations.
• Compact, Production-Friendly Package: φ25 × 25 mm snap-in can in tray packing supports efficient through-hole assembly and inventory management.
• Regulatory Compliance: RoHS compliance simplifies material-conformance management for regulated regions and customers.
