What are the key features of ECH-U1C221GX5?
- Stacked metallized PPS (polyphenylene sulfide) film dielectric delivering ultra-stable capacitance over temperature from -55°C to +150°C
- 220 pF low-capacitance value with mold-less construction enabling compact SMD footprint for high-precision filter and timing applications
- Low ESR and excellent self-healing properties ensuring long-term reliability in high-frequency and high-temperature environments
What is ECH-U1C221GX5 used for?
ECH-U1C221GX5 is suited for precision timing circuits, audio crossover filters, and RF decoupling networks where stable 220 pF capacitance over a wide temperature range is essential. Its PPS film dielectric offers significantly less capacitance drift than ceramic X7R types under DC bias and temperature, making it valuable in oscillator feedback networks and sample-and-hold circuits. The compact SMD form factor allows placement in automotive infotainment modules and industrial sensor signal conditioning boards operating up to 150°C.

Frequently Asked Questions
What dielectric material does ECH-U1C221GX5 use and how does PPS film outperform ceramic capacitors in precision circuits?
ECH-U1C221GX5 uses stacked metallized PPS (polyphenylene sulfide) film as the dielectric, which provides capacitance stability of less than ±1.5% over its operating temperature range from -55°C to +150°C. In contrast, X7R ceramic capacitors can shift by 15% over the same range, making ECH-U1C221GX5 far more accurate for timing, filter, and precision analog circuits requiring stable 220 pF capacitance.
At what voltage rating is ECH-U1C221GX5 specified and in which low-voltage analog circuits is this appropriate?
ECH-U1C221GX5 is rated at 16 V DC working voltage, which is well suited for low-voltage analog signal chains operating from 3.3 V to 12 V supply rails. This 16 V rating gives adequate derating margin in audio preamplifier filter sections, op-amp feedback networks, and sensor interface circuits, where signal voltages rarely exceed 10 V peak and long-term dielectric reliability at 220 pF is more important than high voltage withstand.
How does ECH-U1C221GX5's mold-less PPS construction benefit applications at high operating temperatures?
The mold-less construction of ECH-U1C221GX5 eliminates the polymer overmold packaging that can delaminate or outgas at elevated temperatures, allowing the capacitor to operate reliably up to 150°C. This makes it suitable for under-hood automotive sensor modules, industrial motor drives, and power electronics gate drive circuits where ambient temperatures regularly exceed 85°C and standard plastic-encapsulated capacitors may degrade within their rated lifetimes.
How does ECH-U1C221GX5 compare to 220 pF MLCC C0G capacitors for resonant circuit applications?
Both ECH-U1C221GX5 PPS film and 220 pF C0G MLCCs offer good temperature stability, but PPS film capacitors exhibit lower piezoelectric noise, which reduces microphonics in audio and precision measurement circuits. ECH-U1C221GX5 also provides better self-healing characteristics if dielectric overstress occurs, whereas ceramic capacitors crack without recovery. For resonant circuits at frequencies below 10 MHz, PPS film at 220 pF is a more mechanically robust and quieter option than equivalent C0G ceramics.
