Photoflash Capacitor Charging Transformer SDRS Series

Engineered for rapid energy transfer in compact photoflash systems, the SDRS5630T Series delivers high-efficiency capacitor charging with turns ratios up to 1:25. Its low-profile design and minimized leakage inductance ensure stable performance across industrial temperature ranges (-20°C to +110°C). Optimized for surface mounting (SMD), these transformers feature reinforced insulation (500Vrms withstand voltage) and precision winding for consistent pulse energy delivery in space-constrained applications.

Features

• Ultra-Low Profile: 5.8mm max height for PCB space optimization.

• Minimized Leakage Inductance: Enhances energy transfer efficiency.

• Extended Operating Temp: -20°C to +110°C reliability.

• Surface-Mount (SMD): Automated assembly compatibility.

• High Voltage Isolation: 500Vrms withstand voltage.

• Tape-and-Reel Packaging: Streamlined production (noted as "Rolls Completion" in datasheet).
