LLS2Z821MELZ

The LLS2Z821MELZ is a Nichicon LLS series snap-in aluminum electrolytic capacitor designed for general-purpose power applications. It delivers 820 µF capacitance at a 180 V rating in a compact radial can with snap-in terminals, optimized for bulk energy storage and ripple suppression where a durable, serviceable electrolytic solution is required.

Key value propositions include high ripple-current capability across low and high frequencies, a 3000-hour endurance rating at 85°C, and RoHS compliance—making it suitable for production designs that require reliable performance and regulatory compliance.

Key Features

• Capacitance & Tolerance  820 µF with ±20% tolerance (measured at 120 Hz, 20°C) for predictable bulk storage and filtering.
• Rated Voltage  180 V rated voltage for higher-voltage power systems.
• High Ripple Current  Rated for 2.86 A at 120 Hz (low frequency) and 4.29 A at 50 kHz (high frequency) to support active filtering and dynamic load conditions.
• Endurance & Reliability  Withstanding 3000 hours of rated ripple-current application at 85°C, meeting endurance criteria after recovery to 20°C per the series specification.
• Low Leakage  Specified leakage current of 1150 µA to minimize steady-state loss and maintain performance over time.
• Operating Temperature Range  –40°C to +85°C to cover a wide set of general-purpose operating environments.
• Package & Mounting  Radial, snap-in can (φ22 × 40 mm) with tray packing for secure PCB mounting and production handling.
• Compliance & Availability  RoHS compliant and listed as mass production status, supporting production sourcing and compliance needs.

Typical Applications

• General-purpose power supply filtering  Bulk smoothing and ripple suppression in circuits requiring 180 V-rated capacitors.
• Energy storage for power electronics  Bulk decoupling and transient energy support where high ripple current capability is needed.
• Industrial and commercial electronic equipment  General-purpose use in equipment requiring durable, long-life electrolytic capacitors with snap-in mounting.

Unique Advantages

• High-frequency and low-frequency ripple tolerance  Dual ripple-current specifications (2.86 A at 120 Hz and 4.29 A at 50 kHz) allow designers to address both mains-frequency and switching-frequency disturbances.
• Proven endurance at elevated temperature  Rated for 3000 hours at 85°C under rated ripple current, providing measurable lifecycle expectation in sustained thermal environments.
• Compact snap-in radial can  φ22 × 40 mm package with snap-in terminals enables robust PCB retention and straightforward assembly in rack- and chassis-mounted power designs.
• Controlled leakage for steady performance  Specified leakage current (1150 µA) helps limit parasitic drain and supports predictable system behavior.
• Production-ready supply chain attributes  Tray packing and mass production status simplify procurement and production planning for volume designs.
• Regulatory compliance  RoHS compliance supports regulatory needs for many commercial and industrial products.
