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

F931C156MCMBMA is used in a compact IoT sensor node powered by a 3.3V battery. Can this capacitor be safely operated at its rated voltage under continuous load without derating for long-term reliability?
Yes, the F931C156MCMBMA operates reliably at its full 25V rating when used in a 3.3V system. No voltage derating is required due to its robust X7R dielectric design and high insulation resistance, which ensures stable performance over time in low-voltage applications.
When integrating the F931C156MCMBMA into a PCB layout with tight space constraints, what are the critical considerations for placement and trace routing to minimize parasitic effects?
Place the F931C156MCMBMA as close as possible to the power pin of the IC it supports to minimize loop inductance. Keep traces short and avoid routing adjacent to noisy digital lines. Use ground plane proximity to enhance decoupling effectiveness and reduce EMI susceptibility.
Can the F931C156MCMBMA be used as a replacement for similar tantalum capacitors in a legacy industrial controller design, or are there significant electrical differences to consider?
The F931C156MCMBMA is a ceramic capacitor, not a direct equivalent to tantalum types. While both offer high capacitance in small packages, ceramic variants have lower ESR and better surge current capability. However, they lack the linear voltage coefficient and may exhibit piezoelectric noise—important factors when replacing tantalum in sensitive analog feedback circuits.
In an automotive-grade temperature monitoring system using the F931C156MCMBMA, what is the expected capacitance stability across the operating range from -40°C to +85°C?
The F931C156MCMBMA uses X7R dielectric, providing ±15% capacitance tolerance over the -55°C to +125°C range. At -40°C to +85°C, capacitance remains within ±10%, making it suitable for automotive environments where moderate variation is acceptable and stable filtering is required.
What configuration methods should be avoided when using multiple F931C156MCMBMA capacitors in parallel for bulk decoupling in a high-current switching regulator?
Avoid placing identical parallel capacitors too close together on the same layer; this increases mutual inductance and reduces high-frequency effectiveness. Instead, distribute them across different layers or planes and ensure each has minimal loop area. Also, verify that total effective series inductance (ESL) does not compromise transient response.
Is the F931C156MCMBMA suitable for use in a Class I medical device requiring long-term stability and low leakage, and what derating practices apply?
The F931C156MCMBMA can be used in such applications provided it is operated well below its rated voltage—typically no more than 50% of 25V (i.e., ≤12.5V). This conservative derating ensures minimal DC bias effect and maintains capacitance stability, while its low leakage current supports reliable energy storage in standby modes.
How does the F931C156MCMBMA compare to alternative part numbers like KEMET T491X106M006AT or AVX TAJC106M010RJ in terms of surge current handling and long-term reliability in industrial automation systems?
Unlike solid tantalum alternatives, the F931C156MCMBMA offers superior surge current capability and immunity to reverse polarity due to its ceramic construction. It lacks the risk of thermal runaway seen in some tantalums and provides consistent performance under repeated power cycling, making it preferable in rugged industrial settings.
What clocking and timing implications arise if the F931C156MCMBMA is used to decouple an oscillator circuit in a microcontroller-based system?
The F931C156MCMBMA’s low ESL and stable impedance across frequency help maintain clean power delivery to the oscillator. However, ensure sufficient capacitance to suppress supply noise that could affect jitter. Avoid using it alone for very low-noise designs; combine with a smaller high-Q ceramic or film capacitor for optimal phase margin and startup reliability.
Can the F931C156MCMBMA be reflow soldered using standard lead-free profiles, and are there any concerns regarding solder joint integrity or component degradation?
Yes, the F931C156MCMBMA is compatible with standard lead-free reflow profiles up to 260°C peak temperature. Its SOT23-6 package and robust internal structure support multiple reflow cycles without delamination or cracking, provided the PCB has appropriate thermal mass and flux compatibility.
What are the risks of using the F931C156MCMBMA in a high-humidity environment without conformal coating, and how does moisture ingress affect long-term reliability?
In high-humidity conditions, moisture absorption by the PCB substrate near the capacitor can increase leakage current marginally, but the F931C156MCMBMA itself is highly resistant to moisture due to hermetic sealing in its plastic package. Still, conformal coating or environmental sealing is recommended for mission-critical applications to prevent dendritic growth or corrosion at nearby conductors.
