Key Features
- Stacked metallized PPS film dielectric delivering ±2% capacitance tolerance and less than ±0.5% capacitance change over -55°C to +150°C operating temperature range
- 3300 pF capacitance at 16 V DC rated voltage with extremely low dissipation factor (DF < 0.001) enabling high-Q resonant filter and timing circuits
- Moldless construction reducing parasitic inductance and improving mechanical reliability compared to conventional molded film capacitors in SMT designs
- RoHS-compliant lead-free construction compatible with reflow soldering up to 260°C for environmentally compliant high-reliability PCB assembly
Applications
The ECH-U1C332GX5 is used in precision analog filters, resonant circuits, and RF impedance matching networks where stable 3300 pF capacitance with low dissipation factor is critical across a wide temperature range. Its PPS film dielectric makes it ideal for oscillator timing circuits, active filter stages in audio equipment, and snubber networks in switching power converters operating up to 150°C. The component also suits medical instrumentation and industrial sensor conditioning circuits requiring capacitance accuracy better than ±2% over the full operating temperature range.

Frequently Asked Questions
What capacitance and voltage rating does the ECH-U1C332GX5 provide, and how do these suit precision filter designs?
The ECH-U1C332GX5 provides 3300 pF capacitance at a 16 V DC rated voltage with ±2% tolerance. In a precision bandpass filter centered at 1 MHz using a 7.7 µH inductor, this 3300 pF value sets the resonant frequency with less than 1% center frequency error, enabling stable channel selectivity without trimming components.
How does the PPS film dielectric in the ECH-U1C332GX5 compare to X7R ceramic capacitors for temperature-stable designs?
PPS film capacitors like the ECH-U1C332GX5 exhibit capacitance variation below ±0.5% from -55°C to +150°C, compared to ±15% for X7R ceramics over the same range. This 30x improvement in temperature coefficient makes the ECH-U1C332GX5 preferable for oscillator timing networks and precision integrators where frequency drift below 500 ppm is required across industrial temperature extremes.
What dissipation factor does the ECH-U1C332GX5 achieve, and why does this matter in RF resonant circuits?
The ECH-U1C332GX5 achieves a dissipation factor (DF) below 0.001 at 1 kHz, compared to 0.01–0.03 for general-purpose polyester film capacitors. In an LC resonant tank at 100 kHz, a DF of 0.001 contributes a Q-factor penalty of only 1000 to the circuit, preserving the loaded Q above 200 for narrow-band filter selectivity in RF and IF signal processing stages.
Up to what temperature can the ECH-U1C332GX5 operate, and which high-temperature applications does this enable?
The ECH-U1C332GX5 is rated for continuous operation up to 150°C, covering Class F automotive electronics and industrial power converter environments. This 150°C rating exceeds the 125°C limit of most ceramic capacitors in the same capacitance range, making it suitable for snubber capacitors in IGBT gate drives and DC-link filters where ambient temperatures routinely exceed 105°C.
