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 is the recommended voltage derating for the CWR26HK336JCFA\HR when used in high-reliability power supply decoupling?
For tantalum capacitors like the CWR26HK336JCFA\HR, standard aerospace and military design guidelines typically mandate a 50% voltage derating. While the part is rated for 15V, it is technically optimized for use on power rails not exceeding 7.5V. Using the CWR26HK336JCFA\HR on a 12V rail significantly increases the risk of dielectric breakdown due to the inherent sensitivity of MnO2 tantalum technology to voltage transients and high inrush currents.
How does the 800mOhm ESR of the CWR26HK336JCFA\HR affect its performance in high-frequency switching regulator output stages?
The 800mOhm Equivalent Series Resistance (ESR) of the CWR26HK336JCFA\HR is relatively high compared to modern polymer or multi-layer ceramic capacitors. In a high-frequency switching environment, this ESR will result in higher ripple voltage (V=I*ESR) and increased internal self-heating due to I²R losses. Designers should verify that the calculated RMS ripple current in their application does not exceed the thermal limits of the 2214 case size to prevent premature degradation of the CWR26HK336JCFA\HR.
Can the conformal coated CWR26HK336JCFA\HR be used as a direct substitute for a molded MIL-PRF-55365/4 (CWR11) capacitor?
While the electrical specifications might align, the CWR26HK336JCFA\HR uses a conformal coating rather than a rigid molded case. This results in a different physical profile and terminal structure. The "F" case size (2214) of the CWR26HK336JCFA\HR provides higher volumetric efficiency but lacks the mechanical protection of a molded body. If the application involves high-pressure encapsulation or severe mechanical handling, the lack of a rigid package on the CWR26HK336JCFA\HR may require a review of the assembly process to prevent chipping of the coating.
What are the design implications of the "C" failure rate associated with the CWR26HK336JCFA\HR in mission-critical systems?
The "C" failure rate indicates a reliability level of 0.01% per 1,000 hours at full rated voltage and temperature. When integrating the CWR26HK336JCFA\HR, this standardized MIL-PRF-55365 metric allows engineers to perform precise Mean Time Between Failure (MTBF) calculations for the entire system. This level of Weibull grading ensures that the CWR26HK336JCFA\HR has undergone rigorous exponential distribution testing, making it suitable for long-term deployments where field maintenance is impossible.
Are there specific soldering profile considerations for the CWR26HK336JCFA\HR to avoid thermal shock?
Tantalum capacitors like the CWR26HK336JCFA\HR are sensitive to rapid thermal transitions which can cause cracks in the Ta2O5 dielectric. It is advisable to use a pre-heating phase in the reflow profile to minimize the temperature gradient. Since the CWR26HK336JCFA\HR features a conformal coating, excessive dwell time at peak reflow temperatures (above 250°C) should be avoided to prevent delamination or changes in the ESR characteristics of the 33 µF element.
Why would an engineer select the CWR26HK336JCFA\HR over a commercial-grade T491 or TPS series capacitor?
The primary driver for selecting the CWR26HK336JCFA\HR over commercial alternatives is the requirement for established reliability and traceability. The CWR26HK336JCFA\HR is qualified to MIL-PRF-55365/13, meaning it undergoes stringent surge current testing (Option A, B, or C) and thermal shock testing that commercial parts do not. For applications in defense or space where vacuum stability and outgassing are concerns, the materials used in the CWR26HK336JCFA\HR provide a verified performance baseline that commercial parts cannot guarantee.
Does the ±5% capacitance tolerance of the CWR26HK336JCFA\HR hold across the entire -55°C to 125°C operating range?
No, the ±5% tolerance for the CWR26HK336JCFA\HR is rated at 25°C and 120Hz. At the lower temperature limit of -55°C, the capacitance will decrease due to the temperature coefficient of the tantalum pentoxide dielectric. Conversely, at 125°C, the capacitance of the CWR26HK336JCFA\HR will generally increase. Engineers designing timing circuits or filters must account for this temperature-induced capacitance drift to ensure the circuit remains within functional bounds across the full industrial/military temperature range.
What is the risk of using the CWR26HK336JCFA\HR in a high-impedance circuit without a series resistor?
Unlike older tantalum designs, the CWR26HK336JCFA\HR is built to withstand surge currents, but high-impedance applications still benefit from the self-healing properties of the MnO2 cathode. If the CWR26HK336JCFA\HR is used in a very low-impedance circuit (less than 0.1 ohm per volt), a high-current spike could cause a localized hot spot. However, because the CWR26HK336JCFA\HR is a "High Reliability" graded part, it has already passed surge current testing during manufacturing to mitigate the risk of catastrophic short-circuit failure in low-impedance environments.
