TRANSFORMERS G SERIES

Product catalog summary
Overview: This document provides technical specifications and guidelines for pulse transformers, specifically focusing on catalog items, stock markings, and ordering information. It includes detailed descriptions of various parameters and their significance in transformer performance.
Specifications:
  • Stock Mark: Items with a dot are regularly stocked; others require ordering. Minimum order quantities apply.
  • Catalog Number: Indicates the product number.
  • Turns Ratio: Represents the transformation ratio of each winding.
  • Inductance: Defined as the magnetic flux linkage per unit current. A higher inductance value results in a smaller droop (D).
  • Rise Time (Tr): Represents the rise portion of the pulse waveform. Lower leakage inductance and inter-winding capacitance result in a smaller Tr.
  • Leakage Inductance: Indicates the primary side leakage inductance when the secondary side is shorted.
  • Inter-winding Capacitance: Represents the capacitance between windings.
  • D.C.R. (Direct Current Resistance): Lower values reduce losses during pulse waveform transmission.
  • ET Product: Defines the pulse waveform that can pass through the transformer, calculated as the product of pulse width and voltage.
Pulse Transformer Features:
  • Designed for data transmission.
  • Adaptable to printed circuit boards.
  • Encapsulated design for protection.
  • Maximum average power rating: 500mW (at 40°C rise).
  • Standard dissipation rating: 150mW.
  • Peak pulse voltage: 100V.
  • Dielectric strength: DC500V for 1 minute.
  • Insulation resistance: DC500V, minimum 10000MΩ.
  • Minimum order quantity: 20 pieces.
Installation Note: Pin numbers are not marked; use the white dot (pin #1) for mounting on the printed circuit board.
