What are the key features of ECW-U2473V16?
- Stacked metallized PEN (polyethylene naphthalate) film dielectric for superior frequency stability and low loss
- Mold-less simple construction reduces package size and parasitic inductance for high-frequency xDSL applications
- 47 nF capacitance at 250 V DC rating provides robust DC blocking in telecom line interface circuits
- Self-healing metallized electrode technology for improved reliability and long operational life
What is ECW-U2473V16 used for?
The ECW-U2473V16 is primarily designed for DC blocking in xDSL line interface circuits, where it isolates the AC signal from the DC supply rail across telephone subscriber lines. Its low-inductance stacked film construction makes it well suited for ADSL, VDSL, and HDSL modem designs demanding stable capacitance over a wide frequency range. The component is also applicable in industrial filtering and signal coupling circuits requiring a 250 V rated, 47 nF film capacitor.

Frequently Asked Questions
What are the capacitance and voltage ratings of the Panasonic ECW-U2473V16?
The ECW-U2473V16 has a capacitance of 47 nF and a DC voltage rating of 250 V. These specifications make it suitable for DC blocking duties in xDSL line interface applications, where the capacitor must withstand the telephone line's DC bias while passing high-frequency ADSL or VDSL signals with minimal insertion loss.
Why is PEN film dielectric used in the ECW-U2473V16 for xDSL applications?
Polyethylene naphthalate (PEN) film offers a lower dissipation factor and better thermal stability compared to standard polyester (PET) film, which is critical for xDSL frequencies that can reach up to 30 MHz. The ECW-U2473V16's PEN dielectric maintains stable 47 nF capacitance across temperature and frequency, ensuring consistent DC blocking performance in ADSL and VDSL modem circuits.
How does the mold-less construction of the ECW-U2473V16 benefit circuit board designs?
The mold-less simple construction of the ECW-U2473V16 reduces the overall component height and minimizes parasitic inductance, which is particularly important in high-frequency xDSL circuits operating above 1 MHz. This compact design allows denser PCB layouts, and the self-healing metallized electrodes add reliability without requiring encapsulation, yielding a lighter 47 nF, 250 V capacitor suitable for slim modem equipment.
Can the ECW-U2473V16 be used in applications other than xDSL DC blocking?
Yes, the ECW-U2473V16 is suitable for general-purpose signal coupling and filtering where a 47 nF capacitance at 250 V DC is required. Typical alternative uses include industrial power line filtering, audio coupling stages, and SMPS snubber circuits. Its PEN film dielectric ensures stable performance across a temperature range of -40°C to +85°C, broadening its applicability beyond telecom line interfaces.
