Frequently Asked Questions
What are the key electrical ratings of the HHXA350ARA680MF80G capacitor?
The HHXA350ARA680MF80G offers 68 µF capacitance at 35 V DC with 20% tolerance, an ESR of 35 mΩ (measured at 100 kHz), and a ripple current rating of 1400 mA. It is rated for 4000 hours at 125°C, making it suitable for demanding automotive power supply applications.
Why is low ESR important in the HHXA350ARA680MF80G for automotive DC-DC converters?
Low ESR of 35 mΩ minimizes power dissipation and reduces output voltage ripple in DC-DC switching converters. At 100 kHz switching frequencies typical of automotive regulators, a 35 mΩ ESR value in this 68 µF capacitor ensures stable output voltage and low thermal rise, improving converter efficiency and reliability in engine control and ADAS modules.
How does the hybrid aluminum polymer construction of the HHXA350ARA680MF80G differ from standard electrolytic capacitors?
Aluminum polymer hybrid capacitors combine a solid polymer electrolyte with a small amount of liquid electrolyte, resulting in lower ESR (35 mΩ), higher ripple current capacity (1400 mA), and improved high-temperature lifetime (4000 h at 125°C) compared to standard wet aluminum electrolytic capacitors of similar 68 µF / 35 V ratings.
In which automotive system locations can the HHXA350ARA680MF80G be deployed given its temperature and size rating?
Rated to 125°C and housed in a compact 6.3 x 7.7 mm SMD package, the HHXA350ARA680MF80G can be deployed near under-hood locations such as engine control units, transmission controllers, and electric power steering ECUs. Its 35 V rating and 4000-hour life also suit infotainment power rails and ADAS domain controllers operating in thermally stressed enclosures.
