LGG2E821MELA45

The LGG2E821MELA45 is an aluminum electrolytic capacitor in a snap-in terminal, radial can package designed for general-purpose electronic use. It delivers 820 µF capacitance at a 250 V rating with polarization and a compact form factor aimed at equipment downsizing.

Engineered for robust operation up to 105°C and compliant with the RoHS directive, this Nichicon LGG-series part is specified for applications that require high capacitance and voltage handling in a reduced-case footprint.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance with a 250 V rated voltage; capacitance tolerance is ±20% at 120 Hz, 20°C.
• High Temperature Endurance — Specified endurance of 2000 hours at 105°C when DC bias plus rated ripple current is applied; meets defined capacitance, tan δ and leakage current limits after the endurance test.
• Operating Temperature Range — Usable from −40°C to +105°C for the 160–250 V range, supporting elevated-temperature environments.
• Ripple Current Capability — Rated ripple current of 2 A at 120 Hz and 3 A at 100 kHz, providing defined AC current handling across frequency ranges.
• Leakage Current Specification — Leakage current defined as I ≤ 3√CV (µA) after 5 minutes’ application of rated voltage at 20°C, providing a measurable leakage limit for design validation.
• Snap-in Radial Can Package — Snap-in terminal mounting for secure PCB installation; physical size L: 4.5 × D: 2.5 cm with a seated height maximum of 1.772 inch.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Electronics — Bulk smoothing and energy storage in systems requiring a 820 µF / 250 V capacitor in a compact snap-in package.
• Power Supplies — DC bus filtering and ripple suppression where the specified ripple currents (2 A @120 Hz, 3 A @100 kHz) and 105°C endurance are needed.
• Industrial Equipment — Use in equipment designs that benefit from a reduced-case capacitor for space-constrained assemblies while maintaining high-temperature performance.

Unique Advantages

• Compact size for downsizing: One rank smaller case size (LGG series) helps reduce enclosure and board footprint without sacrificing capacitance or voltage.
• Designed for elevated temperatures: 2000 hours endurance at 105°C supports long-term operation in high-heat environments.
• Defined ripple handling across frequencies: Specified ripple currents at both low and high frequencies enable predictable thermal and electrical behavior.
• Clear leakage current limit: Leakage current defined by I ≤ 3√CV (µA) enables straightforward verification during design and test.
• Snap-in mounting: Robust snap-in terminal reduces assembly variability and supports secure PCB retention in radial-can form.
• Regulatory compliance: RoHS conformity for restricted substances in applicable regions.
