6 FAQs about [Capacitor clearance distance]
How much clearance should a connector have?
If the associated clearance is less than 3 mm, the minimum slot width can be reduced to 1/3 of the clearance. The maximum voltage to be applied to the connector depends on the distance between two connections. Clearance = shortest distance between two conductive parts (in air) Creepage distance = distance along surface
What is the minimum clearance distance for an electrical device?
Consider an electrical device with a working voltage of 250 V AC and a pollution degree of 2. To determine the minimum clearance distance, we can refer to Table 1 below, which is adapted from the IEC 60664-1 standard: Based on the table, the minimum required clearance distance for our example is 1.5 mm.
What is a good lead spacing for a 10kV rated capacitor?
When I have been studying the IPC-2221 and IEC 61010 standards the conductor clearance should be in the order of 0.00305 mm/volt, therefore you would think that for a 10kV rated capacitor the lead spacing should be at least 30.5mm. However, when looking at many datasheets they are around 9.5mm +/-2mm.
What determines the clearance and creepage distances between conductive parts?
Voltage The voltage between conductive parts is a primary factor in determining the necessary clearance and creepage distances. Higher voltages require greater distances to prevent electrical breakdown and surface leakage currents. 2. Pollution Degree
Does Murata have a creepage distance over a capacitor?
You still have the creepage distance over the capacitor surface to contend with- it's probably not adequate unless you coat the board or pot the circuit. By the way, that Murata part has a final order date of 'September 2019, meaning it is marked to be permanently discontinued.
What is the difference between clearances and creepage distance?
Clearances refer to the two adjacent conductors or a conductor with the shortest distance along the surface of the motor housing adjacent to air measurements. Creepage distance is the shortest distance between two adjacent conductors or a conductor and an adjacent surface of the motor housing along the surface of the insulation. In PCBs, both clearances and creepage distance are important electrical safety considerations.
