Broadcast consultant Tom Osenkowsky recently constructed a panel with two vu meters and a DPDT switch. The switch allows him to configure the meters to display conventional Left and Right channels or ...

When choosing a capacitor for any application, there are a few key characteristics that must be understood in order to analyze its suitability for the circuit. In a simple capacitor equivalent circuit ...

Traditionally, RF and high-frequency designs were concerned with parasitics. Today, printed circuit boards (PCBs) and component parasitic elements are becoming an integral part of system designs, even ...

Capacitor discharge circuits are used extensively in fast pulse generation. In such applications, the capacitor's stray inductance (or equivalent series inductance) and series resistance play an ...

A 9-V battery or an optional ac wall adapter can power the Model 881 portable in-circuit equivalent-series resistance (ESR) and dc resistance (DCR) capacitor tester ...

Rutronik has added a lower power Epson 32.768kHz crystal to its line up. Power saving from the FC1610BN comes from its low ESR (effective series resistance) which is typically 45kΩ at +25°C, a maximum ...

I remember debugging a compact PLC power board used in a packaging line. The system worked perfectly on the bench. In the field, it started rebooting every few hours. No obvious faults. No overheating ...
