Product Description
EEL25 High Performance Pulse Transformer Multi-Slot High Voltage Step Up
Product Overview
The EEL25 multi-slot pulse transformer is engineered for high-voltage triggering, pulse signal transmission, and specialized isolation applications. Featuring a multi-section segmented bobbin design, this transformer effectively reduces distributed capacitance, increases creepage distance, and prevents inter-turn high-voltage breakdown. It delivers exceptional insulation, reliable pulse signal integrity, and stable continuous performance under demanding operating conditions.
