LLS2E821MELA

The LLS2E821MELA from Nichicon is an aluminum electrolytic capacitor in a snap-in radial can package engineered for general-purpose electronic applications. It delivers 820 µF capacitance at a 250 V rated voltage with polarized operation and a ±20% tolerance.

Designed to endure continuous ripple stress, the capacitor withstands 3000 hours of rated ripple current at 85°C and is RoHS compliant (2011/65/EU, (EU)2015/863), making it suitable where sustained high-voltage bulk capacitance and reliable PCB-mounted retention are required.

Key Features

• Capacitance & Voltage: 820 µF rated capacitance at 250 V DC with ±20% tolerance, providing substantial high-voltage bulk storage.
• Snap-In Terminal Package: Radial, can-type with snap-in mounting for secure PCB retention and straightforward installation in through-hole assemblies.
• Temperature Range & Endurance: Operates from −40°C to +85°C (applicable for 16 to 250 V items in the series). Endurance validated by withstanding 3000 hours of rated ripple current at 85°C.
• Ripple Current Capability: Rated ripple current of 3.01 A at 120 Hz and 4.515 A at 50 kHz, enabling effective ripple handling in high-stress environments.
• Electrical Loss & Leakage: Series specifications include tan δ max 0.15 at 250 V and leakage current defined as I ≤ 3√CV (µA) after 5 minutes at 20°C, allowing predictable loss and leakage behavior.
• Physical Size: Footprint dimensions L: 4.5 × D: 2.5 cm with a maximum seated height of 1.772 inch, suited to designs requiring compact high-voltage bulk capacitance.
• Compliance: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Electronics: For electronic equipment requiring 820 µF at 250 V where polarized bulk capacitance is needed and snap-in mounting is preferred.
• PCB Snap-In Installations: Fits through-hole PCBs that use snap-in radial can capacitors and require a compact high-voltage capacitor footprint.
• High-Ripple Environments at 85°C: Suitable where continuous rated ripple current is applied at elevated temperature, supported by the 3000-hour endurance at 85°C.

Unique Advantages

• Proven High-Temperature Endurance: 3000 hours of rated ripple current endurance at 85°C provides predictable long-term behavior under sustained thermal and ripple stress.
• High-Voltage Bulk Storage: 820 µF at 250 V offers significant energy storage for circuits that require large capacitance at elevated voltages.
• Robust Mechanical Retention: Snap-in terminals offer reliable through-hole retention and simplified assembly compared with loose-leaded alternatives.
• Measurable Electrical Parameters: Specified tan δ (≤ 0.15 at 250 V) and leakage current formula (I ≤ 3√CV) allow engineers to model loss and leakage precisely.
• Regulatory Compliance: RoHS conformity supports environmentally constrained designs and procurement requirements.
