Key Features

• High Voltage / Capacitance — 400 V rated voltage and 220 µF capacitance provide energy storage suitable for high‑voltage circuits.
• Snap‑in Radial Package — Snap‑in can for secure PCB mounting; package described as radial, can ‑ snap‑in with L: 3 × D: 3 cm size dimensions and a seated height max of 1.181 inch.
• High Ripple Current — Specified ripple current values of 1.79 A at 120 Hz and 2.56 A at 50 kHz support applications with significant ripple stresses.
• 105 °C Endurance — Withstanding 3000 hours at 105 °C when subjected to DC bias plus rated ripple current, per LGW series endurance specification.
• Polarized Electrolytic — Polarized design with capacitance tolerance of −20% to +20% (±20%).
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.
• Leakage Current Specification — Leakage current meets I ≤ 3√(C·V) (µA) after 5 minutes application of rated voltage at 20 °C, as specified for the series.
• Series Identification — Part of Nichicon’s LGW series, marked with white lettering on a black sleeve.

Typical Applications

• Power conversion and filtering — 400 V rating and high ripple current capability make this capacitor suited for smoothing and filtering in general‑purpose power circuits.
• High‑temperature environments — Rated for operation up to 105 °C with 3000‑hour endurance, supporting designs exposed to elevated temperatures.
• Industrial equipment — Snap‑in radial mounting and robust ripple performance address general‑purpose industrial power electronics requiring durable bulk capacitance.

Unique Advantages

• High ripple tolerance: Specified ripple current at both 120 Hz (1.79 A) and 50 kHz (2.56 A) allows designers to select a capacitor matched to the frequency content of their application.
• Long‑term elevated‑temperature endurance: 3000 hours at 105 °C under rated conditions supports reliability in sustained high‑temperature deployments.
• Clear leakage specification: Leakage current limited by I ≤ 3√(C·V) after standard voltage application enables predictable design margins for insulation and standby losses.
• Practical mounting form factor: Snap‑in radial can simplifies board placement and mechanical retention for through‑hole assemblies.
• RoHS compliance: Meets environmental restriction requirements for restricted substances.
