Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

What are the key design considerations when integrating the 1111J2000471GQT into high-frequency RF matching or resonant circuits where low loss is required?
The 1111J2000471GQT from Knowles Syfer features C0G/NP0 dielectric with high Q and low loss characteristics, resulting in minimal energy dissipation and stable performance across frequency in RF applications. Engineers should account for the 1111 (2828 metric) package's parasitic inductance and ensure short, wide traces or vias in the layout to maintain resonance accuracy, while verifying that operating frequencies keep self-heating within limits based on the applied RF voltage and current.
How does the package size and termination of the 1111J2000471GQT affect PCB layout and mechanical stress during assembly or operation?
The 1111J2000471GQT measures 2.79 mm x 2.79 mm with a maximum thickness of 1.78 mm in an MLCC surface-mount configuration. This larger footprint compared to smaller case sizes like 0805 or 0603 provides more electrode area for lower ESR but requires adequate solder pad dimensions and consideration of board flexure; standard nickel/tin terminations are used, and in high-vibration or thermal cycling environments, board-level strain relief techniques may help maintain long-term integrity.
Is the 1111J2000471GQT suitable for replacement in designs originally using smaller case size C0G capacitors such as 0805 or 1206 for 470 pF at 200 V?
When migrating to the 1111J2000471GQT, designers gain benefits from the larger physical size including potentially lower ESR and higher current handling due to more electrode layers or wider current paths, but must adjust pad layouts, recalculate parasitic elements, and verify that the increased footprint fits within the available board space without impacting signal integrity or assembly processes.
What power supply decoupling or bypassing constraints should engineers evaluate when using the 1111J2000471GQT in precision analog or RF circuits?
In precision circuits, the 1111J2000471GQT's ±2% tolerance and C0G/NP0 temperature coefficient support stable bypassing or coupling where voltage coefficients and drift must remain negligible. Its 200 V rating provides headroom for supply transients up to that level, and the high Q behavior helps minimize losses in high-frequency decoupling paths, though proximity to the IC pins and ground plane quality directly influence the effective impedance at the target frequencies.
Under what application conditions might the 1111J2000471GQT not be the optimal choice compared to porcelain or specialized high-power RF capacitors?
For applications involving very high RF power levels or frequencies where even lower ESR or higher voltage standoff is needed beyond the 200 V rating of the 1111J2000471GQT, alternatives with porcelain dielectrics or dedicated high-power series may exhibit different self-heating profiles and Q behavior at elevated power, requiring evaluation of thermal rise and voltage derating curves specific to the operating waveform.
How should engineers approach long-term reliability assessment of the 1111J2000471GQT in industrial equipment operating continuously near the temperature extremes of -55°C to 125°C?
The 1111J2000471GQT operates over -55°C to 125°C with no aging effects typical of Class II dielectrics and maintains stable capacitance due to the C0G/NP0 characteristic. In continuous industrial use, apply standard voltage and temperature derating practices based on the actual applied DC or AC voltage, monitor for any board-level mechanical stress accumulation over thermal cycles, and consider the MSL 1 rating which supports unlimited floor life without special handling for moisture.
What are the practical differences when considering the 1111J2000471GQT versus other 470 pF C0G parts from different manufacturers in terms of Q, ESR, and integration?
The 1111J2000471GQT incorporates Knowles Syfer's high Q, low loss formulation in the 1111 package, which can result in measurably lower dissipation compared to standard commercial C0G MLCCs of similar value in smaller packages. Designers should compare S-parameter data or measured Q at the operating frequency, as well as termination robustness, to determine any adjustments needed in matching networks or filter designs for equivalent performance.
Are there configuration or clocking-related considerations when using the 1111J2000471GQT in oscillator or timing circuits that demand tight capacitance stability?
Due to the inherent stability of the C0G/NP0 dielectric in the 1111J2000471GQT (±2% tolerance), capacitance variation with temperature, voltage, and time remains minimal, supporting consistent frequency control in oscillators. Engineers should still model the full parasitic network including the capacitor's contribution to loop inductance and ensure the 200 V rating accommodates any peak voltages present in the tank circuit.
What factors influence the decision to use the 1111J2000471GQT in high-reliability or long-life industrial systems regarding potential migration from legacy parts?
The RoHS3 compliant and REACH unaffected status of the 1111J2000471GQT, combined with its EAR99 classification, simplifies compliance in industrial designs. When replacing older legacy 470 pF components, verify dimensional compatibility of the 1111 case and assess any differences in thermal mass or soldering profile requirements to avoid unintended shifts in mechanical reliability over extended operational lifetimes.
How does the voltage rating and dielectric behavior of the 1111J2000471GQT affect its use in circuits with potential AC or pulsed signals up to 200 V?
The 200 V DC rating of the 1111J2000471GQT allows operation with AC or pulsed signals provided the peak voltage stays within limits and any resulting RMS heating is evaluated against the low loss properties. The stable C0G/NP0 response ensures capacitance does not shift significantly under bias, enabling predictable filtering or coupling behavior in such mixed-signal or RF power transfer scenarios.
