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 does the 130°C temperature rating of the 50RX3010MT78X11.5 affect the calculated service life when operating in a standard industrial environment of 85°C?
The 50RX3010MT78X11.5 is rated for 2,000 hours at 130°C. Following the Arrhenius law for electrolytic capacitors, which estimates that life doubles for every 10°C decrease in operating temperature, reducing the ambient temperature from 130°C to 85°C (a 45°C delta) theoretically extends the operational life significantly. For the 50RX3010MT78X11.5, this translates to an estimated life exceeding 40,000 hours at 85°C, making it a robust choice for long-term industrial deployments where maintenance cycles are infrequent.
When using the 50RX3010MT78X11.5 in high-frequency switching power supplies, how does its 600 mOhm impedance impact ripple current management compared to standard low-ESR capacitors?
The 50RX3010MT78X11.5 features an impedance of 600 mOhms and is rated for a high-frequency ripple current of 200 mA at 100 kHz. While it provides high thermal stability, its impedance is higher than some dedicated "Ultra-Low ESR" series. Engineers must verify that the self-heating generated by the ripple current through the 50RX3010MT78X11.5 does not exceed the internal thermal limits of the capacitor, particularly in compact DC-DC converter designs where airflow may be restricted.
Can the 100V rated 100RX3010MTA8X11.5 be used as a drop-in substitute for the 50RX3010MT78X11.5 in an existing automotive PCB layout?
The 100V substitute 100RX3010MTA8X11.5 shares the same 8mm diameter and 11.5mm height as the 50RX3010MT78X11.5, making it mechanically compatible for most layouts. However, designers should evaluate the differences in leakage current and dissipation factor, as the higher voltage oxide layer in the 100V version may alter these parameters. Additionally, ensure the lead spacing of the 100V variant matches the 3.50mm pitch used for the 50RX3010MT78X11.5 to prevent mechanical stress on the solder joints during assembly.
What are the risks of using the 50RX3010MT78X11.5 in high-vibration automotive environments, and does its AEC-Q200: qualification cover mechanical mounting concerns?
While the 50RX3010MT78X11.5 is AEC-Q200: qualified, which ensures it has passed rigorous stress testing for automotive use, its radial through-hole package can still be susceptible to lead fatigue in high-G environments. For under-the-hood or chassis-mounted applications, it is recommended to use additional bonding agents or mechanical support to secure the 8mm diameter body of the 50RX3010MT78X11.5 to the PCB, preventing the mass of the capacitor from stressing the 3.50mm lead interface during peak vibration events.
How does the ESR of the 50RX3010MT78X11.5 behave at the lower operating limit of -40°C, and what are the implications for cold-start performance?
Aluminum electrolytic capacitors like the 50RX3010MT78X11.5 experience a significant increase in ESR at low temperatures due to the decreased mobility of the electrolyte. At -40°C, the impedance of the 50RX3010MT78X11.5 will be several times higher than its room-temperature value. In power supply input filtering applications, this may lead to increased ripple voltage and potential startup issues for PWM controllers if the bulk capacitance cannot provide sufficient energy during the initial power-on sequence in extreme cold.
Is the 50RX3010MT78X11.5 suitable for use in non-automotive LED drivers that require high ambient thermal resilience but operate at low frequencies?
Yes, the 50RX3010MT78X11.5 is highly suitable for LED drivers due to its 130°C rating, which accommodates the high internal temperatures often found in compact lighting enclosures. Since the 50RX3010MT78X11.5 is rated for 110 mA of ripple current at 120 Hz, it can effectively handle the low-frequency rectified AC ripple typical of many LED driver topologies while maintaining long-term reliability in heat-intensive environments.
What considerations should be taken regarding the 0.138" (3.50mm) lead spacing of the 50RX3010MT78X11.5 during automated pick-and-place and wave soldering?
The 50RX3010MT78X11.5 comes in Tape & Box (TB) packaging, intended for automated radial insertion machines. Designers must ensure that the PCB footprint hole diameter accounts for the lead thickness of the 50RX3010MT78X11.5 and provides sufficient clearance for solder wetting during wave soldering. Given the 130°C thermal rating of the 50RX3010MT78X11.5, the capacitor can withstand standard wave soldering profiles, but exposure to temperatures exceeding 260°C for more than 10 seconds should be avoided to prevent damage to the internal seals and electrolyte.
