• Conform RoHS

Features

• Higher ripple though use of low-ESR material consequently, the permissible ripple

current is improved by 27% in the windless status or 40% in the ventilated condition

(0.5m/s) as compared with conventional constructions (HU3 series).

• Improvement in air exhaust (flow hole phenomenon) from the terminal insertion hole at

solder fixing though improvement of cap condtruction.

• The operating spase of the safety vent (arranged on the case bottom) is reduced from

5mm (conventional necessary distance) into 1mm through improvement of case

construction. For these new case construction, pattern desigh can be move flexible.

Product Specifications

Product code

Terminal permissible current is limited to 15Arms (

φ41, 46),

20Arms (

φ51).

(Even if calculated the permissible ripple current with the

correction coefficient exceeds 15, 20Arms)

Please consult us when the ripple voltage exceeds 70Vp-p.
