Choosing a heat sink: start with power loss and junction temperature
Calculate the heat sink needed from power loss, ambient temperature, heat path, airflow and mounting.
Choosing an ADC: why more bits do not automatically mean more accuracy
Choose an ADC by signal range, usable measurement resolution, speed, noise and the complete signal chain.
Crystal, resonator or oscillator: which clock source fits?
Choose a crystal, resonator or oscillator that fits the IC, required accuracy and reference design.
Ferrite bead or common-mode choke: what are you filtering?
Choose a ferrite bead or common-mode choke by noise mode, frequency, current and its effect on the wanted signal.
Choosing an oscilloscope: bandwidth, sample rate and probes
Choose an oscilloscope for your signal, capture time and channels, with suitable probes and a safe measurement method.
Choosing a power inductor: understand Isat, Irms and DCR
Choose a power inductor by assessing inductance, peak and RMS current, losses and temperature together.
TVS diode or Zener diode: when should you use each?
Learn when to use a TVS or Zener diode and compare working voltage, clamping voltage and pulse load.
Choosing an op amp: check more than supply voltage and bandwidth
Choose an op amp that fits the supply, signal range and load, with the right bandwidth, offset and noise performance.
Choosing an FFC/FPC cable: check these 5 points
