Key questions and answers

What are the effective lifespan and durability of the UJ series at 105 ℃, and what is the difference between the two?

Answer: The effective lifespan is 5000 hours, which refers to the reliable usage time under long-term rated working conditions; The durability is 2000 hours, which refers to the duration of high-temperature pressure accelerated aging testing, all under 105 ℃ conditions.

What is the upper limit of the loss factor tan δ for different voltage ranges of the UJ series, and how is the leakage current calculated?

Answer: Tan δ ≤ 15% for 200~400V range, Tan δ ≤ 20% for 450~550V range; The leakage current formula is ILEAK ≤ 3 ·√ (CR · VR) μ A, measured at 20 ℃ and after applying the rated voltage for 5 minutes.

How does the UJ series distinguish between the regular version and the AEC-Q200 car specification version, and what are the pin configurations?

Answer: The model suffix with X refers to AEC-Q200 version (such as P6X, Z6X); The pins support 2-pin/3-pin/multi pin, with optional lengths of 4mm/6mm. 3-pin is used for polarity protection, and multi pin is used for large sizes with a diameter ≥ 30mm.
