Key Features

• Capacitance & Voltage: 220 µF capacitance at a 250 V rated voltage for high‑voltage DC filtering and energy storage.
• Long Life Assurance: Rated for 10,000 hours at 105 °C under rated ripple current, supporting extended service life in elevated temperature environments.
• High Temperature Range: Operating temperature range −40 °C to 105 °C to accommodate a wide range of system thermal conditions.
• Ripple Current Capability: Specified ripple current of 1 A at 120 Hz and 1.5 A at 50 kHz; frequency coefficient reaches 1.00 at 120 Hz and up to 1.50 at 50 kHz or more for the 200·250 V range.
• Mechanical & Mounting: Snap‑in terminal, radial can package with physical size L: 3 × D: 2.2 cm and a maximum seated height of 1.181 inch for robust PCB retention.
• Electrical Quality: Capacitance tolerance ±20% and tangent of loss angle (tan δ) max 0.15 for rated voltages in the 200–400 V range.
• Leakage Current Specification: Leakage current meets I ≤ 3√(C·V) μA after 5 minutes’ application of rated voltage at 20 °C, per series specification.
• RoHS Compliant: Complies with the RoHS directive as stated for the LGR series.

Typical Applications

• General‑purpose power filtering: Use for bulk smoothing and decoupling in power supplies that require 250 V rating and 220 µF capacitance.
• High‑temperature environments: Suitable where sustained operation at elevated temperatures is required, leveraging the 105 °C rating and 10,000‑hour long‑life specification.
• High‑frequency ripple environments: Appropriate when designs must handle ripple across a range of frequencies, with specified ripple currents and frequency coefficients up to 1.50 at 50 kHz or more.

Unique Advantages

• Long‑life reliability: 10,000‑hour endurance at 105 °C reduces service interventions and supports longer maintenance intervals.
• High‑voltage capability: 250 V rating enables use in higher DC rail applications without series stacking.
• Robust ripple handling: Rated ripple currents and documented frequency coefficients provide predictable performance across AC and high‑frequency ripple conditions.
• Secure board mounting: Snap‑in terminal and radial can package provide reliable mechanical retention for power electronics assemblies.
• Clear electrical limits: Defined leakage current formula and tan δ limit (0.15 for 200–400 V range) support predictable electrical behavior and validation in designs.
• Regulatory compliance: RoHS compliance supports use in products targeting restricted substance requirements.
