In November of 2016, Munich hosted Electronica 2016. This show is held every two years and is the largest gathering of every aspect of the electronic engineering supply chain. With several of KEMET’s experts in the same place at the same time, James asked some questions of KEMET’s application experts on our booth’s floor.
This episode focuses on what makes our high voltage ceramic capacitor, ArcShield, unique. Mark Laps explains that electrode pattern we print inside of the capacitor is designed to act as a Faraday cage. This technique offers a significant advantage in >500 V applications. ArcShield prevents arc-over failures typically seen with uncoated capacitors while providing more capacitance than traditional high voltage ceramic capacitors.
ArcShield received the Elektra 2016 Award for Passive & Electromechanical Product of Year.
Episode Key Points
- Up to 1,000 V rated ceramics available in 0603
- “Shield” refers to the electrode pattern used
- Ceramic electrode patterns define behavior
- ArcShield does not require special coating (for capacitor or the board)
