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 recommended voltage derating guidelines for the TH3C685M025D1400 when used in automotive 12V or 24V power rails?
For high-reliability applications, the TH3C685M025D1400, which has a 25V rated voltage, should be operated with a minimum 50% voltage derating. This makes the TH3C685M025D1400 ideal for 12V DC buses where transient spikes may occur, but it is technically unsuitable for 24V rails, as the operating voltage would exceed the recommended safety margin for solid tantalum dielectrics, potentially leading to catastrophic failure.
How does the 150°C operating temperature limit of the TH3C685M025D1400 impact the design of under-the-hood engine control units?
Unlike standard tantalum capacitors limited to 125°C, the TH3C685M025D1400 is engineered for continuous operation up to 150°C with appropriate category voltage derating (typically 2/3 of rated voltage above 85°C). In engine control units, the TH3C685M025D1400 provides the necessary thermal headroom to maintain capacitance stability and leakage current performance in ambient environments that exceed the limits of commercial-grade components.
Can the TH3C685M025D1400 effectively replace a 6.8µF 25V MLCC in a precision analog signal chain to eliminate microphonic noise?
Replacing a Class II MLCC with the TH3C685M025D1400 is an effective strategy for eliminating piezoelectric effects and acoustic noise in sensitive signal paths. The TH3C685M025D1400 does not exhibit the DC bias effect common in ceramic capacitors, meaning its 6.8µF capacitance remains stable regardless of the applied voltage, though the 1.4 Ohm ESR of the TH3C685M025D1400 must be factored into the circuit's overall impedance and phase margin.
What are the primary design considerations when substituting the TH3C685M025D1400 with a Kemet T491 or AVX TAJ series C-case capacitor?
When considering alternatives to the TH3C685M025D1400, engineers must evaluate the ESR and temperature ratings; the TH3C685M025D1400 offers 1.4 Ohm ESR and 150°C capability, whereas a standard T491 or TAJ series part may only be rated for 125°C. If the application environment exceeds 125°C or requires AEC-Q200: qualification, a standard industrial part cannot serve as a direct drop-in for the TH3C685M025D1400 without risking premature dielectric degradation.
How does the 1.4 Ohm ESR of the TH3C685M025D1400 influence the output ripple voltage in low-power DC-DC converters?
The 1.4 Ohm ESR of the TH3C685M025D1400 directly determines the magnitude of the ripple voltage (V = I_ripple * ESR). While this ESR value helps in stabilizing certain LDO regulators that require a specific range of output resistance, it may result in higher peak-to-peak ripple compared to ultra-low ESR polymer capacitors; therefore, the TH3C685M025D1400 is best suited for decoupling or filtering where moderate ESR is beneficial for damping oscillations.
Is the TH3C685M025D1400 suitable for high-vibration industrial environments as defined by AEC-Q200: standards?
Yes, the TH3C685M025D1400 is AEC-Q200: qualified, which involves rigorous mechanical shock and vibration testing. The molded 2312 (6032 Metric) package of the TH3C685M025D1400 provides robust mechanical termination to the PCB, making it significantly more resistant to board flex and vibration-induced cracking than large-case ceramic capacitors, which is a critical factor in industrial machinery and automotive safety systems.
What is the impact of reflow soldering profiles on the long-term reliability and leakage current of the TH3C685M025D1400?
The TH3C685M025D1400 is sensitive to moisture absorption and thermal stress during reflow; following the J-STD-020 standard is necessary to prevent "popcorning" or dielectric damage. Proper handling of the TH3C685M025D1400 ensures that the DC leakage current remains within the specified limits post-assembly, as excessive heat can cause mechanical stress at the tantalum-anode interface, increasing the risk of localized heating during power-on.
