Frequently Asked Questions
What voltage and capacitance does the ECW-U4473V17 provide?
The ECW-U4473V17 provides 0.047 µF capacitance at a 400 VDC rating with a 5% tolerance, making it suitable for high-voltage filtering and energy storage in power electronics applications requiring more than 350 V operation.
Which industrial applications benefit most from the ECW-U4473V17 film capacitor?
Motor drive inverters, AC line EMI filters, and power factor correction circuits operating at up to 400 VDC benefit most. The 0.047 µF value and film dielectric provide low ESR and high ripple current capability needed in these 3-phase industrial environments.
How does the 2820 package size of ECW-U4473V17 compare to smaller film capacitors in compact designs?
The 2820 footprint measures approximately 7.2 mm × 5.0 mm, larger than 1210 ceramic alternatives, but the film construction offers superior voltage handling up to 400 VDC and better long-term capacitance stability over 10,000 operating hours.
When should a designer choose ECW-U4473V17 over an electrolytic capacitor of similar value?
When the circuit requires non-polarized AC-coupling, snubber, or resonant tank operation at up to 400 VDC, ECW-U4473V17 is preferred because film capacitors tolerate bidirectional voltage stress and maintain capacitance within 5% over a wide temperature range of -55°C to +105°C.
