Key Features

• Capacitance & Voltage — 330 µF rated capacitance with a 200 V nominal rating and ±20% tolerance (at 120 Hz, 20 °C).
• High‑temperature endurance — Specified to withstand 2000 hours application of rated ripple current at 105 °C, supporting reliable operation in elevated temperature environments.
• Snap‑in radial can package — Snap‑in terminal mounting for secure PCB installation; package dimensions L: 3 × D: 2.5 cm are provided for board layout.
• Ripple current capability — Rated ripple current performance of 1.05 A at 120 Hz and 1.26 A at 10 kHz, suitable for smoothing and power supply applications subject to AC ripple.
• Safety performance — Improved safety features for abnormally excessive voltage and a pressure relief vent designed to operate without dangerous conditions such as flames or case dispersion.
• Leakage and loss characteristics — Leakage current specified per datasheet (I ≤ 3√CV µA after 5 minutes at 20 °C) and tan δ ≤ 0.20 at 120 Hz, 20 °C.
• Regulatory compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Polarized device — Intended for polarized circuit applications; observe polarity during assembly.

Typical Applications

• General‑purpose electronic equipment — Bulk capacitance and ripple handling for power supply smoothing and energy storage in general industrial and electronic circuits.
• Equipment in voltage‑fluctuating areas — Enhanced safety features and extended voltage options make the part suitable for systems exposed to irregular supply conditions.
• High‑temperature applications — Rated for continuous operation and endurance testing at 105 °C, supporting use where elevated ambient or internal temperatures are expected.

Unique Advantages

• Extended voltage family — Part of an LAK series that offers extended voltage ranges (200 V, 400 V, 420 V), enabling consistent selection across different system voltages.
• Proven high‑temperature endurance — 2000 hours at 105 °C with rated ripple current demonstrates robustness for demanding thermal conditions.
• Clear safety design — Pressure relief vent and specified safety testing limit hazardous outcomes during abnormal overvoltage events.
• Measurable ripple performance — Published ripple current values at 120 Hz and 10 kHz allow designers to size capacitors against expected AC stress.
• Regulatory assurance — RoHS compliance supports deployments where restricted‑substance conformance is required.
