Würth Elektronik Capacitors

Aluminum for high capacitance density

film for high-frequency and reliability. For best performance, ensure proper installation following manufacturer guidelines. Contact BeiLuo FAE team for application-specific recommendations and design support. We provide comprehensive technical documentation, samples for evaluation, and production scheduling for high-volume requirements. Our technical team can assist with schematic review, layout optimization, and troubleshooting to ensure successful implementation in your design.

Use aluminum for bulk; film for high-frequency apps.

ESR affects heating and ripple voltage. Lower is better for switching supplies. For best performance, ensure proper installation following manufacturer guidelines. Contact BeiLuo FAE team for application-specific recommendations and design support. We provide comprehensive technical documentation, samples for evaluation, and production scheduling for high-volume requirements. Our technical team can assist with schematic review, layout optimization, and troubleshooting to ensure successful implementation in your design.

Select low ESR for high-frequency applications.

Lifetime depends on temperature and voltage stress. Rule of thumb: half for every 10°C rise. For best performance, ensure proper installation following manufacturer guidelines. Contact BeiLuo FAE team for application-specific recommendations and design support. We provide comprehensive technical documentation, samples for evaluation, and production scheduling for high-volume requirements. Our technical team can assist with schematic review, layout optimization, and troubleshooting to ensure successful implementation in your design.

Derate voltage and temperature for longer life.

X capacitors across lines

Y capacitors line-to-ground for safety. For best performance, ensure proper installation following manufacturer guidelines. Contact BeiLuo FAE team for application-specific recommendations and design support. We provide comprehensive technical documentation, samples for evaluation, and production scheduling for high-volume requirements. Our technical team can assist with schematic review, layout optimization, and troubleshooting to ensure successful implementation in your design.

Use X for differential; Y for common mode filtering.

X5R and X7R are most common. X7R has better temperature stability. For best performance, ensure proper installation following manufacturer guidelines. Contact BeiLuo FAE team for application-specific recommendations and design support. We provide comprehensive technical documentation, samples for evaluation, and production scheduling for high-volume requirements. Our technical team can assist with schematic review, layout optimization, and troubleshooting to ensure successful implementation in your design.

Use X7R when capacitance stability is critical.
