What are the key features of ECW-U4683V17?
- 0.068 µF capacitance at 400 VDC rating gives wide voltage headroom for AC line filtering, snubber, and high-voltage coupling circuits
- Polyethylene naphthalate (PEN) film dielectric provides excellent self-healing characteristics and stable capacitance over temperature
- Non-polarized chip construction in 2825 package enables surface-mount assembly and bidirectional AC circuit use
- Tight ±5% capacitance tolerance ensures consistent filter corner frequencies and resonance tuning in precision designs
What is ECW-U4683V17 used for?
The ECW-U4683V17 is used in AC-line EMI filtering, motor-drive snubber networks, and power-factor correction circuits where a robust 400 VDC rating and stable dielectric are essential. Its 0.068 µF PEN film construction suits resonant tank circuits in switching power supplies operating at frequencies up to several hundred kilohertz. The compact 2825 SMD package also makes it suitable for high-density inverter PCBs and industrial ballast circuits requiring non-polarized, high-voltage capacitors.

Frequently Asked Questions
What capacitance and voltage rating does the Panasonic ECW-U4683V17 provide for high-voltage circuits?
The ECW-U4683V17 provides 0.068 µF of capacitance at a rated voltage of 400 VDC with ±5% tolerance. This high voltage rating makes it suitable for AC line filtering, snubber circuits in motor drives, and switching power supplies where bus voltages can reach 380 V to 400 V under worst-case conditions.
Why is a PEN film dielectric preferred in motor-drive snubber circuits over a standard polyester film?
Polyethylene naphthalate (PEN) film has a higher thermal stability than standard polyester (PET) film, retaining capacitance values within tighter limits across temperatures ranging from -40°C to +105°C. In motor-drive snubber applications, where voltage spikes and thermal cycling stress the capacitor repeatedly, PEN film's self-healing property and lower dissipation factor reduce the risk of catastrophic failure compared to PET film capacitors.
Can the ECW-U4683V17 be used in AC circuits, and what is the significance of its non-polarized construction?
Yes. Being a non-polarized film capacitor, the ECW-U4683V17 can be connected in any orientation in both AC and DC circuits without risk of polarity reversal damage. This makes it directly applicable to AC line EMI filtering, resonant tank circuits, and power-factor correction stages that require a capacitor to handle bidirectional voltage swings at line frequencies of 50 Hz or 60 Hz.
How does the 2825 chip package of the ECW-U4683V17 affect PCB layout for high-voltage designs?
The 2825 SMD package (7.0 mm x 6.4 mm footprint) provides a stable mechanical base and short lead inductance compared to leaded film capacitors, which reduces parasitic ringing in snubber and filter circuits. The surface-mount format also allows automated placement, improving assembly throughput for inverter and ballast boards that incorporate multiple 400 VDC film capacitors.
