The DB60 Series is designed specifically for power supplies using microgap technology to discharge surges.
With a 5mm pitch and a small body size, the part takes up very little space on the board.
■ Characteristics
• The 5mm pitch; radial
taped parts can be mounted using automaticinsertion equipment.
• Superior surge response
characteristcs due to microgap technology.
• High insulation resistance
of over 100MΩ.
