High-Frequency Telecom Transformer | 100kHz - 10MHz+
Product Overview Precision-engineered Telecom Transformers (Signal/Pulse Transformers) designed for high-frequency signal transmission, impedance matching, and galvanic isolation. Operating efficiently across a wide frequency range (100 kHz to 10 MHz+), these transformers feature low turn counts and an approximate 1:1 primary-to-secondary ratio to ensure signal integrity with minimal distortion. Available in compact core geometries like Toroid, EE/EI, and RM.
