Key Features
- 120 nF stacked metallized PEN film dielectric with mold-less construction for ultra-low parasitic inductance in xDSL DC blocking
- 250 VDC rating with high insulation resistance ensures reliable long-term operation in telecom line interface circuits
- Stable capacitance over temperature range supports consistent xDSL signal coupling and DC blocking performance
Applications
ECW-U2124V16 is designed primarily for DC blocking in xDSL line interface units, ADSL, VDSL, and POTS splitter circuits where the capacitor must pass high-frequency signals while blocking DC line voltage up to 250 VDC. Its stacked metallized PEN film construction provides low equivalent series inductance, making it ideal for DSLAM port cards and CPE modem line interfaces requiring precise 120 nF capacitance values. The mold-less design also suits compact surface-mount telecom board assemblies with tight height constraints.

Frequently Asked Questions
What capacitance value and voltage rating does ECW-U2124V16 provide for xDSL DC blocking?
ECW-U2124V16 provides 120 nF capacitance at a 250 VDC voltage rating, delivering the correct DC blocking impedance and voltage holdoff needed in xDSL and ADSL line interface circuits at subscriber loop voltages up to 48 V DC with transient protection margins.
How does the mold-less PEN film construction of ECW-U2124V16 benefit high-frequency xDSL signal coupling?
The mold-less stacked metallized PEN film construction of ECW-U2124V16 minimizes package-induced series inductance, maintaining stable 120 nF capacitance and low ESR at the 17 MHz to 30 MHz VDSL signal band for accurate DC-blocking without attenuating high-frequency xDSL data signals.
In which telecom board designs is ECW-U2124V16 specified as a DC blocking capacitor?
ECW-U2124V16 is specified in DSLAM port cards, ADSL/VDSL CPE modems, and POTS splitter boards where 120 nF film capacitors at 250 VDC must block subscriber line DC bias while passing xDSL signals at frequencies from 25 kHz up to 30 MHz with minimal insertion loss.
What dielectric material does ECW-U2124V16 use and how does it affect capacitance stability?
ECW-U2124V16 uses a polyethylene naphthalate (PEN) film dielectric, which exhibits lower capacitance drift with temperature compared to polyester (PET) film, ensuring the 120 nF blocking capacitance stays within tight tolerance over the operating temperature range of telecom line cards in central office and outdoor cabinet environments.
