What are the key features of ECW-U2103V16?

  • 10 nF capacitance with 250 V DC rating in a compact 4.8 × 3.3 mm footprint using stacked metallized PEN film for stable high-frequency performance
  • Mold-less construction reduces parasitic inductance and improves high-frequency impedance characteristics essential for xDSL DC blocking and signal coupling
  • PEN (polyethylene naphthalate) film dielectric provides superior thermal stability and self-healing properties compared to standard PET film capacitors at equivalent voltage ratings

What is ECW-U2103V16 used for?

The ECW-U2103V16 is specifically designed for DC blocking and signal coupling in xDSL modem line interfaces, ADSL/VDSL subscriber line cards, and telecom line driver circuits. Its 250 V rating and stable PEN film dielectric also make it effective in industrial signal conditioning, audio coupling stages, and high-voltage measurement circuits requiring low-loss AC signal passing with DC isolation.

Frequently Asked Questions

What capacitance value and voltage rating does the ECW-U2103V16 provide for telecom designs?

The ECW-U2103V16 offers 10 nF (0.01 µF) capacitance with a 250 V DC voltage rating, making it suitable for DC blocking in xDSL line interfaces where high voltage withstand and stable capacitance are required to protect downstream circuitry from DC line potentials up to 250 V.

Why is PEN film chosen over PET for the ECW-U2103V16 dielectric and what are the benefits?

Panasonic uses polyethylene naphthalate (PEN) film instead of standard PET because PEN exhibits higher thermal stability up to 125°C, lower dielectric absorption, and better self-healing characteristics after voltage stress events, resulting in longer capacitor life and more stable 10 nF capacitance in xDSL operating environments.

How does the mold-less construction of ECW-U2103V16 improve high-frequency performance?

The mold-less package eliminates the added mass and parasitic inductance associated with standard molded housings, reducing equivalent series inductance (ESL) and improving impedance characteristics at frequencies above 1 MHz, which is critical for xDSL applications where signal frequencies span 25 kHz to 30 MHz.

Can ECW-U2103V16 be used in audio coupling applications beyond xDSL?

Yes, the ECW-U2103V16's 10 nF capacitance and 250 V rating are suitable for audio signal coupling stages in high-voltage tube amplifiers and professional audio equipment, where the PEN film dielectric provides low distortion, minimal dielectric absorption below 0.1%, and reliable DC blocking up to 250 V.
