上一篇文章咱们讲了LDO输出电容容值的选型计算，今天咱们聊聊在选LDO输出电容时，输出电容的ESR，也就是等效串联电阻有哪些注意事项。别看它不起眼，这家伙可是LDO稳定性和性能的“幕后英雄”。选不好，LDO电路可能直接“罢工”，选对了，就能让你的设计 ...

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 ...

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 ...

10 kHz. Additional measured parameters include Z, L, C, DCR, D, Q, and B;. The meter features a large, easy-to-read LCD display, autoselection, and a 0.5% basic accuracy.

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. It measures ESR and DSR from 0.1 ...

This charging stand for iPhone, Apple Watch, and AirPods doesn't just support cutting-edge induction charging standard Qi2.2. "This design solves one of the biggest consumer frustrations when using ...
