• Long‑Life, High‑Temperature Endurance — Endurance specification of 5000 hours at 105 °C under rated ripple conditions to support extended operation in hot environments.
• Ripple Current Capability — Rated ripple handling of 2.18 A at 120 Hz and 3.27 A at 50 kHz, enabling effective smoothing under both low‑ and high‑frequency ripple loads.
• Operating Temperature Range — Specified for −25 °C to +105 °C to accommodate a wide range of industrial and commercial thermal environments.
• Package & Mounting — Radial, snap‑in can package (22 × 50 mm) for secure PCB mounting in power assemblies and easy insertion during assembly.
• Polarized, ±20% Tolerance — Polarized device with capacitance tolerance of −20% to +20% for predictable design calculations.
• Leakage Current — Typical leakage current of approximately 1.21 mA for the 820 µF, 200 V size (as listed in the LGX series dimension table).
• RoHS Compliance — Manufactured in compliance with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Rectifier Circuits for Inverters — Provides bulk capacitance and ripple smoothing in rectifier sections of general inverter designs.
• Switching Power Supplies — Supports energy storage and output filtering where sustained ripple current and elevated temperature endurance are required.
• General‑Purpose Power Electronics — Suitable for smoothing and decoupling tasks in a variety of commercial and industrial power assemblies.

Unique Advantages

• Extended High‑Temperature Life: 5000 hours at 105 °C under rated ripple ensures long service life in sustained thermal stress conditions.
• Measurable Ripple Performance: Specified ripple currents (2.18 A at 120 Hz, 3.27 A at 50 kHz) allow designers to match capacitor selection to expected ripple profiles.
• High Voltage Capability: 200 V rating supports higher‑voltage DC link and rectifier applications without stepping down system voltage.
• Snap‑In Packaging for Robust Mounting: Radial snap‑in can (22 × 50 mm) provides a secure mechanical and electrical connection for power boards.
• Predictable Specifications: Clear tolerance (±20%), leakage current reference (~1.21 mA), and temperature range simplify design verification and BOM selection.
• RoHS‑Compliant Manufacturing: Meets current RoHS requirements for regulatory conformity in commercial and industrial products.
