Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

Ceramic capacitors are small, they don’t leak, they’re convenient, but they are downright strange. Certain types of caps will lose their capacitance depending on the voltage they’re operating at. If ...

Vishay’s 299 PHL-4TSI series of snap-in aluminum electrolytic capacitors includes a diverse selection of 350-V, 500-V, 550-V, and 600-V devices. Recent additions significantly broaden the ...

Occasionally a design requires capacitors that are much closer to being identical in value to one another than the usual ...

KEMET has successfully developed several new part types with industry-leading and first-to-market capacitance values that offer both high voltage capability and the stability and performance of C0G ...

In mission-critical applications, the need for stability and durability goes beyond financial considerations or minor inconveniences. When downtime could result in serious security breaches or even ...

Electronic circuits are integral parts of nearly all the technological advances being made in our lives today. Television, radio, phones and computers immediately come to mind, but electronics are ...

Megger’s new CDAX 605 test set measure capacitance and dissipation factor at high voltages. Megger’s new CDAX 605 test set measure capacitance and dissipation factor at high voltages. Faster and ...

Electrochemical capacitors, also called supercapacitors, store energy using either ion adsorption (electrochemical double layer capacitors) or fast surface redox reactions (pseudo-capacitors). They ...
