Features & benefits

  • High capacitance (330 µF) at 500 VDC for demanding DC link and power supply filtering applications.
  • Screw‑terminal construction for secure, low‑impedance connections to busbars or heavy wiring.
  • Relatively low ESR (420 mΩ) and 3.5 A ripple rating enable better thermal and performance margins.
  • ALS30 series reliability with 11,000‑hour rated lifetime and wide operating temperature range.

Handling & installation notes

  • Confirm polarity before installation and apply recommended torque to screw terminals to avoid seal or terminal damage.
  • Ensure adequate cooling and spacing to meet ripple current specification and prolong service life.
  • For volume orders, verify current lead times; Mouser stock and expected replenishment dates are provided above.
