New Yorker Electronics has announced Cornell Dubilier Electronics’ (CDE) expansion of its signature 380LX and 381LX aluminium electrolytic capacitor series to include voltages up to 600VDC.

According to CDE, the new ratings are designed to serve the company’s industrial electronics customers who continue to push the application boundaries for these components into higher voltages.

The CDE 380LX and 381LX 600VDC Snap-in series boast a published load life of 3,000 hours when tested at rated voltage and ripple current at rated temperature.

The 380LX series is designed for 85 °C operation, while the 381LX series meets the same load life at 105°C.

These components demonstrate exceptional life in real-life applications where conditions are typically lower than the capacitor’s maximum specified ratings.

Newly added capacitance values in the range of 15 µF to 330µF are offered at 550 and 600Vdc in the 380LX series and 140µF to 340µF at 500, 550 and 600Vdc in the 381LX series.

Developed at CDE’s technology centre in Liberty, SC, these new ratings are offered with enhanced ripple current capability, up to 3.7A at full-rated conditions. The company’s latest advances in electrolyte development, materials and processing technology make their higher voltage ratings and excellent performance possible.

The company expects these higher voltage snap-in capacitors to be used in the latest inverter circuits for renewable energy, UPS systems, battery chargers, motor drives, welders and other applications that require the highest performance components to improve system reliability.
