LLS2W820MELZ

The LLS2W820MELZ is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LLS series, designed for general-purpose applications. It combines a 450 V rating with an 82 µF capacitance in a polarized, radial snap-in can for through-hole mounting.

Key value propositions include robust ripple-current endurance at elevated temperature and RoHS compliance, making it suitable for designs that require high-voltage filtering with proven long-term stability under rated conditions.

Key Features

• Rated Capacitance & Voltage — 82 µF capacitance with a 450 V rated voltage for high-voltage circuits.
• Snap-in Mounting — Radial, can-type snap-in terminals for secure through-hole installation.
• Endurance at Elevated Temperature — Specified to withstand 3000 hours application of rated ripple current at 85 °C.
• Ripple Current Performance — Rated ripple current of 860 mA at 120 Hz and 1.23 A at 50 kHz for demanding ripple conditions.
• Operating Temperature Range — –25 °C to 85 °C compatible with the 350–450 V category temperature specification.
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20 °C.
• Polarized Design — Polar capacitor construction for DC applications that require polarity.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint — Physical dimensions: length 2.5 cm × diameter 2.2 cm; seated height specified as 2.5 cm.

Typical Applications

• High-voltage DC filtering — Use in circuits requiring a 450 V rated capacitor with defined ripple-current capability for smoothing and energy storage.
• Power supply smoothing — Appropriate where sustained ripple handling and 3000-hour endurance at 85 °C are required.
• General-purpose industrial electronics — Suited for general-purpose designs that need a through-hole, snap-in aluminum electrolytic capacitor with RoHS compliance.

Unique Advantages

• Long-term ripple endurance — Built to withstand 3000 hours of rated ripple current at 85 °C, supporting reliability in elevated-temperature applications.
• Measured ripple specifications — Explicit ripple-current ratings at 120 Hz (860 mA) and 50 kHz (1.23 A) allow engineers to size components against real operating conditions.
• Secure mechanical mounting — Snap-in terminal can reduces handling and assembly variability for through-hole designs.
• High-voltage capability — 450 V rating enables use in higher-voltage DC circuits where lower-voltage capacitors are not suitable.
• Standards-compliant material set — RoHS compliance aligns the part with regulatory requirements for restricted substances.
• Compact, defined package — Clear physical dimensions simplify board layout and mechanical integration in constrained assemblies.
