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

Why should an engineer select the 1206 package size for a capacitance as low as 1.8pF, as seen in the C1206X189D1HACAUTO, instead of a smaller 0402 or 0603 footprint?
Selecting the C1206X189D1HACAUTO in a 1206 package is typically driven by mechanical and reliability requirements rather than electrical density. The larger 1206 footprint, combined with KEMET’s flexible termination technology, provides superior resistance to board-flex stress and thermal cycling compared to smaller packages. In automotive environments where PCB bending or vibration is prevalent, the C1206X189D1HACAUTO reduces the risk of ceramic cracking that could lead to short circuits.
How does the X8R dielectric of the C1206X189D1HACAUTO perform in high-temperature engine compartment applications compared to standard X7R capacitors?
The C1206X189D1HACAUTO utilizes X8R dielectric, which is rated for stable operation up to 150°C, whereas standard X7R capacitors are limited to 125°C. For "under-the-hood" automotive electronics, the C1206X189D1HACAUTO maintains its capacitance value with minimal drift at these elevated temperatures, ensuring that high-frequency noise filtering or timing circuits remain within specification under extreme thermal conditions.
What are the design implications of the ±0.5pF tolerance when integrating the C1206X189D1HACAUTO into a high-frequency RF matching network?
Since the nominal capacitance of the C1206X189D1HACAUTO is 1.8pF, a ±0.5pF tolerance represents a variance of approximately 27%. In precision RF matching or narrow-band filtering, this absolute tolerance can cause significant shifts in center frequency. Engineers using the C1206X189D1HACAUTO should perform Monte Carlo simulations to ensure the circuit remains functional across the full tolerance range or use it in applications where broadband decoupling is the primary objective.
Can the C1206X189D1HACAUTO be used as a direct replacement for a C0G/NP0 capacitor in a high-precision analog timing circuit?
Replacing a C0G part with the C1206X189D1HACAUTO requires careful evaluation of the temperature coefficient. While C0G dielectrics offer near-zero capacitance change over temperature, X8R dielectrics like that in the C1206X189D1HACAUTO exhibit a ±15% capacitance change from -55°C to +150°C. If the application requires high precision over temperature, the C1206X189D1HACAUTO is better suited for bypass or decoupling rather than frequency-determining timing loops.
How does the "Low ESL" feature of the C1206X189D1HACAUTO improve performance in high-speed digital decoupling scenarios?
The internal electrode structure of the C1206X189D1HACAUTO is optimized to minimize Equivalent Series Inductance (ESL). In high-speed automotive data buses, lower ESL allows the 1.8pF capacitor to maintain a lower impedance at Gigahertz frequencies. This ensures that the C1206X189D1HACAUTO effectively suppresses high-frequency electromagnetic interference (EMI) before it can propagate through the system.
What specific advantages does the soft termination of the C1206X189D1HACAUTO provide in high-vibration industrial or automotive environments?
The soft termination in the C1206X189D1HACAUTO incorporates a conductive silver epoxy layer between the base metal and the nickel plating. This layer acts as a buffer that absorbs mechanical energy from PCB flexure or vibration. By utilizing the C1206X189D1HACAUTO, designers mitigate the risk of "flex cracks" which are a primary failure mode in surface-mount ceramic capacitors used in harsh environment electronics.
Is the 100V rating of the C1206X189D1HACAUTO sufficient for 48V automotive electrical systems?
Yes, the 100V rating of the C1206X189D1HACAUTO provides a significant safety margin for 48V automotive rails. This headroom is necessary to withstand transient voltage spikes and load dump conditions common in modern vehicle architectures. Using the C1206X189D1HACAUTO ensures the component operates well within its dielectric breakdown limits, enhancing long-term reliability in power-sensitive modules.
When migrating from a standard MLCC to the C1206X189D1HACAUTO, are there any changes required to the solder reflow profile?
The C1206X189D1HACAUTO is compatible with standard lead-free reflow profiles (RoHS compliant). However, because the C1206X189D1HACAUTO features a flexible termination, engineers should ensure that the peak reflow temperature and cooling rates follow KEMET’s recommendations to avoid compromising the polymer layer. The MSL 1 rating of the C1206X189D1HACAUTO simplifies handling, as it does not require specialized dry-pack storage before assembly.
