LLS2Z821MELA

The LLS2Z821MELA is an aluminum electrolytic, snap-in terminal capacitor designed for 85°C standard operation. It provides 820 µF capacitance at a rated voltage of 180 V with ±20% tolerance and is specified for general purpose applications.

This part delivers robust ripple-current capability (2.75 A at 120 Hz, 4.125 A at 50 kHz), defined leakage current performance, and a 3000 hour endurance at 85°C, packaged in a φ25×35L snap-in can and supplied in tray packing. It is RoHS compliant.

Key Features

• Capacitance & Voltage: 820 µF nominal capacitance at a rated voltage of 180 V with ±20% tolerance for general-purpose DC energy storage needs.
• Ripple Current Performance: Rated ripple current of 2.75 A at 120 Hz (low frequency) and 4.125 A at 50 kHz (high frequency) to support AC ripple handling within specified conditions.
• Endurance and Reliability: Specified for 3000 hours at 85°C under rated conditions; capacitance change within ±20%, tan δ ≤ 200% of initial spec, and leakage current at or below initial specified value after endurance test.
• Loss Characteristics: tan δ (loss tangent) specified at 0.15 max (measured at 20°C, 120 Hz) for the 180 V rating.
• Leakage Current: Specified leakage current of 1150 µA (after 5 minutes' application of rated voltage at 20°C per datasheet conditions).
• Package & Mounting: Snap-in terminal radial can (φ25×35L) intended for snap-in mounting; supplied in tray packing for mass production handling.
• Operating Temperature Range: –40°C to +85°C per category specification for this voltage range.
• RoHS Compliance: Manufactured in conformance with RoHS requirements listed in the product data.

Typical Applications

• General Purpose Electronic Equipment: Intended for use where a high-capacitance, snap-in aluminum electrolytic is required within the –40°C to +85°C operating range.
• Power Supply Circuits: Suitable for general purpose DC circuits that require 820 µF at 180 V and specified ripple-current ratings for filtering and energy storage in standard environments.
• Industrial and Production Environments: Tray-packed format and snap-in mounting support efficient assembly and high-volume production for general-purpose electronic modules.

Unique Advantages

• High Ripple Current Capability: Supports 2.75 A at 120 Hz and 4.125 A at 50 kHz, enabling reliable ripple handling within the specified frequencies.
• Long Endurance at Rated Temperature: 3000 hours endurance at 85°C with defined limits for capacitance change, tan δ, and leakage current provides predictable long-term behavior.
• Compact Snap-in Packaging: φ25×35L radial can with snap-in terminals simplifies board-level mounting and mechanical retention in production assemblies.
• Predictable Electrical Losses: tan δ specified at 0.15 (20°C, 120 Hz) for the 180 V rating, aiding designers in accounting for dissipation and AC performance.
• Controlled Leakage Current: Leakage current specified at 1150 µA under defined test conditions for predictable standby and bias behavior.
• RoHS Compliant: Conforms to RoHS requirements as stated in the product data for environmental compliance considerations.
