Surface Mount Capacitors For DC-DC Converter Applications …
Tantalum, polymer, ceramic, film, and aluminum capacitors each offer a different set of operating and performance characteristics. Choosing the proper capacitor when designing DC-DC converters requires a careful understanding of these differences. High voltage front-end connections to the power source typically rely on aluminum capacitors, while
Understanding ESR and ESL in Capacitors
High ESR capacitor dissipates heat in high current application and the capacitor life decrease eventually, which also contributes to the malfunction in electronics circuits. In power supplies, where high current is a concern, the low ESR capacitors are required for filtration purposes. ... A huge improvement can be seen in today''s SMD ...
The Basics of SMD and SMT: A Comprehensive Guide
The electronics manufacturing business is characterized by a high level of professionalism. Individuals who have knowledge in this domain tend to use fundamental abbreviations to express their requirements, including but not limited to PCB (printed circuit board), PCBA (PCB assembly), and Through Hole Technology (THT), among others. In …
Polarised capacitor vs. unpolarised capacitor. Which to use when?
Tiny SMD capacitors (not polarized) have very low ESR so are used to filter out RF noise, and are often less than 1/4 inch from the device that needs them. In DC power supply feeds both polarized and non-polarized are used and safe as long as polarized capacitors are inserted correctly and no capacitor is exposed to a voltage …
Capacitor Terminations and Soldering Recommendations
Above precaution given for SMD types are applicable for the implementation of large bare chips (1515 and above). But in general, large bare chips above 2225 are not recommended to be mounted on epoxy printed board due to the thermal expansion mismatch between ceramic capacitor body and epoxy. This is the reason why leaded components will be ...

Differentiating between SMD Resistors & Capacitors
Hi all, pictured is the bottom side of TI''s PTN78060HAH DC-DC converter. I''m trying to determine the differences between the -WAH and -HAH models, as the latter is available on the market and the other isn''t. I''m …
Differentiating between SMD Resistors & Capacitors
Hi all, pictured is the bottom side of TI''s PTN78060HAH DC-DC converter. I''m trying to determine the differences between the -WAH and -HAH models, as the latter is available on the market and the other isn''t. I''m assuming (based on limited experience) that all 2-lead non-black SMD components are capacitors: all beige, tan, and blue components.
