LLS2W151MELZ

The LLS2W151MELZ is a snap‑in terminal aluminum electrolytic capacitor providing 150 µF capacitance at a rated voltage of 450 V. It is a radial, can‑style, snap‑in component designed for general‑purpose use where high‑voltage bulk capacitance and durable ripple handling are required.

Engineered for sustained operation up to 85°C, the unit offers a 3000‑hour endurance under rated ripple conditions and is supplied in tray packing for production use. RoHS compliance is specified for environmental regulation alignment.

Key Features

• Capacitance & Voltage — Rated at 150 µF and 450 V, delivering high‑voltage bulk capacitance in a compact φ22 × 40 mm can.
• Tolerance — ±20% tolerance at 20°C and 120 Hz for predictable capacitance in design margins.
• Ripple Current Capability — Low‑frequency ripple current of 1.18 A (120 Hz) and high‑frequency ripple current of 1.687 A (50 kHz) to support sustained AC loading.
• Dielectric Loss (tan δ) — Specified tan δ of 0.2 at 20°C and 120 Hz to characterize dissipation factor at operating conditions.
• Leakage Current — Specified leakage current of 770 µA to help define insulation characteristics under rated voltage.
• Endurance — Withstands 3000 hours of rated ripple current application at 85°C per series specifications, with defined limits on capacitance change, tan δ, and leakage after the endurance test.
• Operating Temperature Range — Rated for −25°C to +85°C operation for applications within this thermal envelope.
• Package & Mounting — Radial, snap‑in can package (snap‑in terminal type) for mechanical retention and board mounting in through‑hole assemblies; supplied in tray packing for mass production.
• Compliance — RoHS‑compliant as specified for the series.

Typical Applications

• General‑Purpose Electronics — Provides 150 µF at 450 V in designs requiring high‑voltage bulk capacitance with snap‑in mounting for through‑hole assemblies.
• High‑Voltage Power Modules — Suitable for modules that require sustained ripple handling and long endurance at elevated temperatures up to 85°C.
• Industrial Power Assemblies — Fits use cases that need robust, long‑life electrolytic capacitance in a radial can form factor and tray packing for production use.

Unique Advantages

• High‑Voltage Bulk Capacitance: 150 µF at 450 V provides substantial energy storage for high‑voltage designs.
• Defined Ripple Performance: Measured low‑ and high‑frequency ripple current ratings (1.18 A @ 120 Hz, 1.687 A @ 50 kHz) let designers size components to actual AC stress.
• Long Endurance at Elevated Temperature: Specified 3000 hours at 85°C under rated ripple current supports predictable life in sustained thermal environments.
• Through‑Hole Snap‑In Reliability: Snap‑in terminal and radial can package provide mechanical retention for assemblies and ease of placement in through‑hole production processes.
• Traceable Performance Parameters: Tangent of loss angle (tan δ), leakage current, and tolerance values are specified for engineering verification and margining.
• Production‑Ready Packaging: Tray packing and mass production status simplify procurement and assembly planning.
