Q: What is the difference between an SMD trigger transformer and a through-hole trigger transformer?

A: An SMD (surface-mount) trigger transformer is designed for automated SMT assembly. It has a smaller footprint and is ideal for high-density PCB designs. Through-hole versions are generally preferred for applications requiring higher mechanical strength or manual assembly.

Q: How does pulse rise time affect circuit performance?

A: A shorter pulse rise time produces a steeper trigger pulse, allowing switching devices such as SCRs and TRIACs to turn on more quickly and reliably. This helps reduce switching losses and improves overall circuit performance.

Q: What information is required for a custom design?

A: To customize a trigger transformer, please provide the required turns ratio, inductance, withstand voltage (isolation voltage), and package dimensions. Our engineering team will recommend the most suitable design for your application.
