54 ELECTROLYTIC CAP REPLACEMENT

Electrolytic Capacitor Replacement Overview:

ï¶ Select electrolytic capacitors can be replaced with MLCC without sacrificing quality or performance

ï¶ TDK can work with our customers to study the electrolytic capacitors used in their designs

ï¶ The primary focus is on decoupling and smoothing capacitors for noise suppression

ï¶ Other circuit applications such as bulk capacitance are also studied if applicable

ï¶ By measuring initial performance, TDK can recommend alternative MLCCâs

Electrolytic Capacitor Replacement Benefits:

ï¶ Worldwide shortage of Ta caps has generated interest by many companies

ï¶ MLCCâs offer a technological advantage as well as a more robust design

ï¶ In some cases, electrolytic cap replacement can result in reduced component count

ï¶ Use of MLCCâs will reduce space usage on PCB and cost of components & lower cost of assembly

ï¶ Lower inherent ESR & increased reliability

Voltage Code

* MLCCâs do not have voltage de-rating rule so you can use up to the full rated voltage

Determine the circuit's function and replace at the minimum acceptable cap value

*Based on circuit function, MLCC cap value may not need to be a 100% replacement

Step 3 Base on application, identify the suggested MLCC replacement part number by referencing your current TA/ALU capacitance and current working voltage (WV)
