55658

Bourns Inc. 55658 is listed under the Current Sense Transformers category and is commonly used when correctness, reliability, and qualification repeatability matter. Designers validate turns ratio, leakage, insulation system, creepage/clearance, and thermal rise at operating frequency. They often define safety margins and EMC behavior in SMPS, PoE, pulse transmission, and sensing solutions. In industrial SMPS, transformer design determines safety margins and efficiency inside sealed enclosures with limited airflow. In measurement systems, current-sense and pulse transformers enable clean transmission under high dv/dt switching conditions. In telecom power modules, isolation supports stable operation and regulatory compliance across multi-board systems. Overall, it strengthens system robustness by aligning electrical, thermal, and mechanical constraints with real deployment conditions.
