Key Features
- Stacked metallized PPS (polyphenylene sulfide) film dielectric provides superior temperature stability and low dissipation factor compared to PET or PP film alternatives
- Mold-less construction minimizes package size and parasitic inductance, making the ECW-U1682JX5 suitable for high-frequency filtering and precision timing circuits
- 6800pF at 100V DC rating covers a wide range of signal-filtering, coupling, and decoupling applications in audio, RF, and power-conversion circuits
Applications
The ECW-U1682JX5 is well suited for precision signal filtering, coupling, and resonant tank circuits in audio amplifiers, switching power supplies, and RF equipment where low dissipation factor and stable capacitance are critical. Its PPS film dielectric maintains capacitance within tight limits across −55°C to +100°C, making it appropriate for automotive auxiliary electronics, industrial measurement instruments, and precision analog signal chains. The compact mold-less package fits into space-constrained PCB layouts in high-frequency filter networks and oscillator circuits requiring a reliable 6800pF reference capacitor.

Frequently Asked Questions
What dielectric does the ECW-U1682JX5 use, and how does it compare to standard PET or PP film capacitors in temperature stability?
The ECW-U1682JX5 uses a stacked metallized PPS (polyphenylene sulfide) film dielectric, which provides a temperature coefficient of capacitance significantly tighter than PET film—typically within ±200 ppm/°C across −55°C to +100°C, compared to ±500 ppm/°C or more for PET. This stability makes PPS film capacitors preferable in precision filter networks, oscillator circuits, and measurement instruments where capacitance drift would degrade frequency accuracy or phase margin.
At what voltage and capacitance is the ECW-U1682JX5 rated, and what filter applications can it support?
The ECW-U1682JX5 is rated at 6800pF (6.8nF) with a 100V DC working voltage and ±5% capacitance tolerance. At 6800pF, it resonates with a 10µH inductor at approximately 609 kHz, making it suitable for low-pass or band-pass LC filters in the 100kHz to 1MHz range used in switching power supply input filters, EMI suppression networks, and audio crossover circuits operating at up to 100V rails.
What is the significance of mold-less construction in the ECW-U1682JX5, and which PCB assemblies benefit from it?
Mold-less construction means the ECW-U1682JX5 does not use an encapsulating resin or plastic shell over the wound capacitor element, resulting in a smaller package body and lower parasitic series inductance typically below 5nH. This lower ESL improves high-frequency filtering performance above 1 MHz, which benefits RF decoupling networks, switching converter output filters, and precision analog circuits where a conventional molded capacitor's higher inductance would degrade suppression of high-order noise harmonics.
