LLS2D102MELZ

The LLS2D102MELZ from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LLS series designed for general‑purpose power applications. It combines a 200 V rated voltage with 1000 µF capacitance and a radial snap‑in can package for robust chassis or PCB mounting.

Engineered for elevated ripple handling and extended life, this part is targeted at applications that require bulk energy storage and smoothing under continuous operating stress up to 85°C, while meeting RoHS requirements.

Key Features

• Rated Capacitance: 1000 µF nominal with ±20% tolerance at 120 Hz, 20°C for bulk energy storage and decoupling.
• Rated Voltage: 200 V DC rating suitable for higher‑voltage power circuits.
• Snap‑in Radial Can Package: φ22 × 50 mm body (L: 5 × D: 2.2 cm) with snap‑in terminals for secure mechanical mounting in chassis and power assemblies.
• Ripple Current Capability: 3.28 A at 120 Hz (low frequency) and 4.92 A at 50 kHz (high frequency) to support high ripple environments and reduce temperature rise under load.
• Low Loss (tan δ): Maximum tan δ of 0.15 measured at 20°C, 120 Hz, indicating controlled dielectric dissipation for stable performance.
• Leakage Current: Specified leakage current of 1340 µA after rated voltage application, for predictable standby characteristics.
• Operating and Endurance Rating: Rated for operation from −40°C to +85°C and endurance of 3000 hours at 85°C under rated ripple/current conditions.
• Regulatory Compliance: RoHS compliant as part of the Nichicon LLS series.

Typical Applications

• General‑Purpose Power Supplies: Bulk smoothing and ripple reduction in 200 V DC rails where sustained ripple current and long life are required.
• Industrial Power Electronics: Energy storage and filtering in industrial converters and controllers operating within −40°C to +85°C.
• Power Conversion Systems: DC link and intermediate energy buffer applications that demand a combination of high voltage rating and robust ripple handling.

Unique Advantages

• High Voltage and Capacitance in a Compact Package: 200 V rating with 1000 µF capacitance provides substantial energy density for high‑voltage circuits while maintaining a φ22 × 50 mm footprint.
• Strong Ripple Handling: Specified low‑ and high‑frequency ripple currents (3.28 A at 120 Hz, 4.92 A at 50 kHz) help minimize heating and improve reliability under continuous AC superimposed loads.
• Extended Endurance at Elevated Temperature: 3000 hours rated life at 85°C under rated conditions supports long‑term deployment in demanding thermal environments.
• Stable Loss Characteristics: Low tan δ (0.15 at 20°C, 120 Hz) reduces dissipation and contributes to predictable performance in AC‑loaded circuits.
• Robust Mounting: Snap‑in radial can format provides secure mechanical retention for chassis or board assemblies in power systems.
• Compliance‑Ready: RoHS compliance aligns with modern regulatory requirements for electronic assemblies.
