To help PCBs and other physically connected components survive vibration, board bending, thermal mismatching, and stress during thermal cycling, Knowles Precision Devices has launched a range of leaded standoff components, Metal Frame J-Lead Terminal MLCCs, that are qualified to AEC-Q200. AEC-Q200 is the global standard for stress resistance in passive electronic components in automotive applications.

Capacitors serve many crucial functions in power electronic circuits. Their ability to store electric charge makes them essential components for regulating and smoothing power flow.
Many of these capacitors are standard fare, but a few play highly specialized, functional roles. To meet application-specific demands, these capacitors must be selected carefully based on function, size, and interoperability.

As a fundamental component of circuit design, equivalent series resistance (ESR) is the measurement of all the non-ideal electrical resistances in series with a capacitor. When current flows through a multilayer ceramic capacitor (MLCC) due to application of alternating voltage, heat is generated in the MLCC due to the losses, specifically ESR. As a result, this self-heating can cause various performance and reliability issues in the circuits of today’s more complex and smaller electronic systems.

The power electronic systems in an electric vehicle (EV) feature a wide variety of capacitors. From DC-link capacitors to safety capacitors and snubber capacitors, these components play a critical role in stabilizing and safeguarding the electronics from factors like voltage spikes and electromagnetic interference (EMI). Here, we’ll focus on the capacitors used in the EV traction inverter.

MRI systems are so robust and require so much infrastructure that they need their own dedicated room—until recently.
A portable magnetic resonance imaging (MRI) system, or point of care (POC) MRI machine, is a compact, traveling device that’s designed for patient imaging outside of the traditional MRI suite (e.g., emergency rooms, ambulances, rural clinics, field hospitals, etc.)
