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

What is creepage distance?

Creepage distance, on the other hand, is the shortest path along the surface of an insulating material between two conductive parts or between a conductive part and the grounded surface of the equipment. This distance is crucial in preventing surface leakage currents, which can occur due to contamination, moisture, or other environmental factors.

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 are clearance and creepage distances?

Two critical factors that contribute to this goal are clearance and creepage distances. These distances play a vital role in preventing electrical breakdowns, short circuits, and other hazardous situations. What is Clearance Distance?

How does a board measure creepage?

However, instead of measuring distance in air, it measures the shortest distance along the surface of the insulation material. Board material and environment also affect creepage requirements. Moisture or particulate accumulation on the board can shorten creepage distance the same way they do for clearance.

Why are creepage distances not replenishable?

At high frequencies or in large clearances, the ions are trapped between the electrodes, since the polarity changes too rapidly for them to be extracted at either end. Unlike clearances, creepage distances and solid insulation are not replenishable because permanent damage, such as carbonized tracking and puncture, are likely.
