LLS2Z821MELB

The LLS2Z821MELB is an aluminum electrolytic capacitor in a snap-in terminal can, specified for 85°C standard operation and designed for general-purpose applications. It provides high-voltage bulk capacitance (820 µF at 180 V) with rated ripple current capability and long endurance for sustained operation.

Key value propositions include robust ripple-current handling at both low and high frequencies, defined leakage and dissipation characteristics, and a 3000-hour endurance rating at 85°C under rated ripple conditions—making it suitable where sustained bulk energy storage and filtering are required.

Key Features

• Electrolytic Snap-In Construction Snap-in terminal type in a radial can package for secure board mounting and high-current connections.
• Nominal Capacitance & Voltage 820 µF rated capacitance at a 180 V nominal voltage with ±20% tolerance at 120 Hz, 20°C.
• Dissipation Factor (tan δ) Low-loss characteristic with tan δ of 0.15 at 20°C measured at 120 Hz for the 180 V rating.
• Ripple Current Capability 2.69 A at 120 Hz (low frequency) and 4.035 A at 50 kHz (high frequency) to support heavy AC ripple conditions.
• Leakage Current Specified leakage current of 1150 µA after standard charge conditions.
• Endurance and Reliability Rated for 3000 hours at 85°C with requirements for capacitance change within ±20%, tan δ within 200% of initial specification, and leakage current not exceeding initial specified value after the endurance test.
• Operating Temperature Range Specified for −40°C to +85°C operation (for the 180 V rating).
• Compact Size & Packing Physical dimensions φ30 × 25L and supplied in tray packing for production handling; listed as mass production status.
• RoHS Compliant Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering — Bulk smoothing and energy storage for high-voltage DC supplies using 180 V rails.
• DC link and energy reservoirs — Where sustained ripple current and bulk capacitance are required in general-purpose power circuits.
• Industrial electronics — General-purpose industrial control and power subsystems that require defined endurance and temperature range.

Unique Advantages

• High-voltage bulk capacitance: 820 µF at 180 V provides substantial stored energy per component for high-voltage DC circuits.
• Defined ripple performance: Rated ripple currents specified at both 120 Hz and 50 kHz to address a range of AC ripple conditions.
• Long endurance under ripple load: 3000-hour endurance at 85°C with post-test limits for capacitance, tan δ and leakage current to support long-term reliability planning.
• Robust leakage and dissipation specs: Leakage current and tan δ values are specified for predictable loss and standby behaviour.
• Production-ready packaging: Tray packing and mass production availability simplify procurement and assembly for volume designs.
• Regulatory compliance: RoHS conformity for use in restricted-substance environments.
