Class 2 capacitors can be divided in: those with a moderate temperature dependence (X7R or 2C1) and others that only a fraction of the capacitance remains at the temperature limits (Z5U or 2F4).
Capacitors with Class 1 ceramic are manufactured with temperature coefficients between +100 and –1500 ppm/°C. In tables and diagrams we will confine ourselves to the type that is called NP0 or COG (0 ± 30 ppm/°C)
When doing the layout for a filter in both wired or PCB formats, BE CAREFUL with the I/O feedback, routing the lines correctly minimizing the parasitic feedback.
Usage increasing of higher frequencies for today’s power-conversion applications has designers looking at planar magnetics devices over traditional transformers What’s the difference between both?
The automotive demand is not just for ICs like processors, memories, power, sensors…, passive components such as capacitors are needed to ensure high stability and interference-free designs
With large capacitor banks, an inrush current limiter is a necessary component, a MOSFET as a voltage-controlled current device is perfectly suitable to be part of an inrush-current limiter
Varistors can be used as suppressors to protect devices and circuits from transient abnormal voltages including an ESD (electrostatic discharge) and a lightning surge
