LGG2E182MELC45

The LGG2E182MELC45 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGG series, designed for compact, general‑purpose power applications. It delivers 1.8 mF capacitance at a 250 V rating and is optimized for equipment downsizing through an ultra-smaller-sized snap‑in can construction.

Built for elevated operating temperatures, the device is rated for use from −40 °C to +105 °C and is RoHS compliant, suitable for designs requiring polarized, high‑voltage bulk capacitance with proven endurance data from the LGG series.

Key Features

• Capacitance and Voltage: 1.8 mF (1800 µF) rated at 250 V for high‑voltage bulk energy storage in a compact package.
• Snap‑in Radial Package: Radial, can‑style snap‑in terminals simplify board mounting and mechanical retention for vertical mounting arrangements.
• High Temperature Rating: Operating temperature range −40 °C to +105 °C with endurance specified for 2000 hours at 105 °C.
• Ripple Current Capability: Rated ripple current of 2.5 A at 120 Hz and 3.75 A at 100 kHz to support steady AC superposition on DC bias.
• Polarized with Standard Tolerance: Polarized electrolytic design with capacitance tolerance of −20% to +20%.
• Electrical Stability and Loss: tan δ spec applicable to the rated voltage range (160–420 V) with tan δ (max.) 0.15; low‑temperature impedance stability Z(−25 °C)/Z(+20 °C) ≤ 4 for 160–250 V.
• Leakage Current Specification: Leakage current meets I ≤ 3√(C·V) (µA) after 5 minutes at 20 °C, per the series specification.
• Endurance and Shelf Life: After DC bias plus rated ripple for 2000 hours at 105 °C, capacitance change within ±20%, tan δ ≤ 200% of initial, and leakage current ≤ initial specified value; shelf life defined for 1000 hours at 105 °C followed by voltage treatment.
• RoHS Compliant and Marking: Compliant with RoHS directives and marked with white lettering on a black sleeve for polarity identification.
• Physical Size: Body dimensions approximately L: 4.5 × D: 3.5 cm in the LGG ultra‑smaller series footprint.

Typical Applications

• General‑purpose power electronics: Bulk energy storage and decoupling in equipment that requires compact, snap‑in capacitors with a 250 V rating.
• Industrial and commercial equipment: High‑temperature environments up to 105 °C where long endurance (2000 h at 105 °C) is needed.
• Equipment downsizing projects: Designs targeting reduced case size benefit from the LGG series’ ultra‑smaller‑sized snap‑in format.

Unique Advantages

• Compact footprint: One‑rank smaller case sizing in the LGG series helps reduce PCB area and enclosure volume.
• High‑temperature endurance: Rated for 2000 hours at 105 °C, providing predictable long‑term performance in elevated temperature applications.
• Robust ripple handling: Defined ripple current ratings at both 120 Hz and 100 kHz support mixed‑frequency ripple conditions.
• Clear electrical specifications: Leakage current formula and tan δ limits enable straightforward design margin calculations.
• RoHS compliance: Conforms to RoHS directive requirements for material compliance in commercial products.
• Easy polarity identification: White marking on a black sleeve simplifies assembly inspection and reduces installation errors.
