MHBA upgraded seriesThe main improvements
New voltage ratings
3 additional voltages: the series is extended toward higher voltage ratings, up to 1100Vdc and 550Vac. This is reached with new material and new design keeping under control the corona effect and the possible detrimental effects related to high ionization levels
Improved robustness under high humidity
Passed ref. tests: AEC Q-200 D, 40°C 93% RH 1000h, at Ur or Urms; IEC60384-17:2019 Grade II, 40°C 93% RH 1344h = 56 days, at Ur or Urms; IEC60384-17:2019 Grade III, high robustness, 60°C 93% RH 1344h = 56 days, Ur (Urms not admitted) / not applicable for lug terminal executions
Extended nominal capacitance range
from 0.22µF to 75µF
Improved pulse withstanding capability
from 25V/µs to 320V/µs
