Glossary of Terms:
Method of attaching unit to panel chassis which does not provide any electrical connections.
Style or type of core structure. Core geometries have been developed for use in different circuit applications.
A core structure that is made of usually silicon steel metal pieces shaped like “E’s” and “I’s”.
Ferrite E Core:
An “E” shape structure made from dense, homogeneous ceramic materials made by mixing iron oxide with oxides or carbonates of one or more metals such as manganese, zinc, or magnesium. An E-core transformer requires two core pieces per transformer.
A doughnut shape structure made from dense, homogeneous ceramic materials made by mixing iron oxide with oxides or carbonates of one or more metals such as manganese, zinc, or magnesium.
Frequency at which transformer will operate
Maximum isolation voltage from winding to winding(s) or winding to core / ground.
Length of time in seconds to test device at the hipot voltage.
The voltage applied to the primary winding
The method used to mount the component to the circuit board.
Number of Primaries:
Number of primary windings. Indicate if center tapped.
Number of Secondaries:
The number of secondaries required in the transformer.
Output current expected to flow through secondary winding(s) under fully loaded conditions.
Output voltage expected from secondary winding(s) under fully loaded conditions.
Powder Core Toroid:
A doughnut shaped structure designed to have distributed air gaps within its shape made from ferrous alloy powder which result in low losses.
Maximum power transformer is expected to process
A signal that varies with time as per the sinusoidal trigonometric function.
Components manufactured with solder feet that are soldered to pads on the circuit board providing the mounting and connection to the circuit. Electrical connection is made through soldering the component to these solder pads.
A signal made by switching between two voltage at a constant frequency.
Thru Hole Mounting:
Component manufactured with pins that mount the device through holes in the circuit board which are soldered making the electrical connection to the circuit.
The number of primary turns to the number of secondary turns expressed as Np:Ns.
Type of signal that is applied to the input terminals of the transformer.
