• Manufacturer Part Number: SF3-DC5V
• Description: 480ch 8bit Tft Lcd Source Driver With Mini-lvds Interface
• Manufacturer: ETC-unknow

The table below shows the state of the other contacts when the current through the welded form “a” contact is 0 V and the rated volt-
age is applied through the form “b” contact.
2) 3a1b Type
If the form “b” contact (No. 3) welds, the armature becomes non-operational, the contact gaps at the three form “a” contacts are
maintained at greater than 0.5 mm
When the form “a” contacts (nos. 1, 2, and 4) weld, the armature remains in a non-returned state and the contact gap at the single
form “b” contact is maintained at greater than 0.5 mm

Note: Contact gaps are shown at the initial state.
If the contacts change state owing to loading/breaking
it is necessary to check the actual loading.
