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

How much voltage derating is recommended when integrating the 199D225X0025A2C1 into a 12V or 15V industrial power rail?
For long-term reliability in solid tantalum capacitors like the 199D225X0025A2C1, a standard derating of 50% is typical. While this capacitor is rated for 25V, operating it at 12V provides a substantial safety margin against voltage transients. In a 15V application, the 199D225X0025A2C1 still operates within a safe 40% derating threshold, which is generally acceptable for most industrial environments, though lower impedance power paths may require closer attention to surge currents.
Can the 199D225X0025A2C1 be used as a primary output filter in high-frequency DC-DC switching regulators?
The 199D225X0025A2C1 belongs to the Tantalex™ general-purpose series and is not specifically characterized for ultra-low ESR (Equivalent Series Resistance). In high-frequency switching applications, the ESR of this 2.2µF radial capacitor may lead to internal self-heating and higher output ripple compared to polymer tantalum or ceramic alternatives. The 199D225X0025A2C1 is better suited for bypass, coupling, or decoupling applications where the frequency demands are moderate and the stability of tantalum over temperature is a primary design requirement.
What are the risks of substituting the 199D225X0025A2C1 with a 10% tolerance part like the 199D225X9025A1V1?
Substituting the 199D225X0025A2C1 (20% tolerance) with the 199D225X9025A1V1 (10% tolerance) is technically feasible from a capacitance standpoint, as the tighter tolerance will always meet the original spec. However, the "A1V1" suffix indicates a different lead spacing or packaging style compared to the 0.100" (2.54mm) lead spacing of the 199D225X0025A2C1. Engineers must verify the PCB hole pitch, as forcing the leads to fit can stress the conformal coating and lead to moisture ingress or dielectric failure.
How does the conformal coating of the 199D225X0025A2C1 impact its performance in high-humidity environments compared to molded tantalum capacitors?
The 199D225X0025A2C1 uses a flame-retardant conformal epoxy coating which provides a smaller physical profile (0.173" diameter) than molded radial tantalums. While this coating offers excellent protection for general-purpose use, conformal-coated parts like the 199D225X0025A2C1 may be more susceptible to moisture absorption over very long periods in non-hermetic, high-humidity environments compared to plastic-molded parts. If the application is intended for high-humidity industrial sensing, additional board-level conformal coating is often applied over the 199D225X0025A2C1.
Is the 199D225X0025A2C1 suitable for applications that experience occasional reverse voltage transients?
Solid tantalum capacitors, including the 199D225X0025A2C1, are polar devices and have very limited tolerance for reverse voltage. Even brief negative excursions can degrade the tantalum pentoxide dielectric. If the 199D225X0025A2C1 is used in a circuit where reverse voltage is possible, such as a motor control feedback loop, a small Schottky diode should be placed in parallel with the capacitor to clamp the reverse voltage to less than 10% of the rated DC voltage.
What mechanical considerations apply to the 199D225X0025A2C1 when designing for high-vibration aerospace or automotive secondary systems?
The through-hole radial design of the 199D225X0025A2C1 provides a more robust mechanical connection to the PCB than surface-mount capacitors of similar value. To maximize the fatigue life of the leads in high-vibration settings, the 199D225X0025A2C1 should be mounted flush to the board or secured with a non-conductive bonding agent to prevent the 0.280" tall body from oscillating, which could eventually lead to work-hardening and fracture of the copper leads.
Does the 1000-hour lifetime rating at 85°C mean the 199D225X0025A2C1 will fail shortly after this period?
The 1000-hour rating for the 199D225X0025A2C1 at 85°C is a standard endurance test specification, not an absolute wear-out point. Solid tantalum capacitors do not have a liquid electrolyte that evaporates, so they do not "dry out" like aluminum electrolytics. When operated within rated voltage and temperature limits, the 199D225X0025A2C1 can achieve a very long service life; however, the failure rate is statistically tied to the application's circuit impedance and voltage stress levels rather than simple time-at-temperature.
How should in-rush current be managed when the 199D225X0025A2C1 is used in a low-impedance battery-powered circuit?
In circuits with extremely low source impedance, the 199D225X0025A2C1 can be exposed to high surge currents during initial power-up. Because tantalums can fail catastrophically if the surge energy exceeds the dielectric's capability, it is advisable to maintain a series resistance of at least 1 ohm per applied volt if possible. If the 199D225X0025A2C1 must be used in a zero-resistance path, the power supply's soft-start ramp should be verified to ensure dV/dt stays within limits that prevent excessive peak charging currents.
