All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

All analog measurements — voltage, current, temperature, humidity, etc. — include some amount of error. Your job is to minimize those errors enough to give your ...

While ac internal resistance (ACIR) measurements are quite common and somewhat standardized when measuring lithium-ion cells, dc internal resistance (DCIR) measurements are nonstandard and generally ...

In this interview Dr Tim Ashworth, Applications Manager at Zurich Instruments talks to AZoM about the latest innovations in Impedance Analyzers. Tim explains the key challenges in the world of ...

Ceramic capacitors play an oversized role in circuit performance as a major contributor to voltage regulator control loop stability and power delivery network (PDN) impedance. When designing with ...

Specifics on ac resistance and why ACIR has become a standard measurement for Li-ions. The 1-kHz test frequency for ACIR and why it's the benchmark frequency. Comparing ACIR test vs. electrochemical ...
