Most devices will recover within 24 hours time. It should be noted that there is no quality defect nor change in protection levels during the temporary change in DCBD. • Sparkover limits ± 25% and IR >108 Ω after life. • At delivery AQL 0.65 Level II, DIN ISO 2859. • Bourns recommends reflowing surface mount devices per IPC/JEDEC J-STD-020 rev D. (2) Network applied. (3) DC Sparkover may exceed ±20 % after discharge, but will continue to protect without venting.
