Glossary of Terms Pulse Transformer

Glossary of Terms:

Duty Cycle:
The percentage of time a pulse is on in relation to the switching period: D=t(on)/T(s).

Hipot:
Maximum isolation voltage from winding to winding or winding to core / ground.

Hipot Duration:
Length of time in seconds to test device at the hipot voltage.

Input Voltage:
The pulse voltage applied to the primary winding.

Mounting:
The method used to mount the component to the circuit board.

Number of Secondaries:
The number of secondaries required in the transformer.

Operating Temperature:
The operating temperature is the anticipated maximum temperature the transformer is expected to operate expressed in degrees Celsius.

Output Currents:
Output current flowing through the secondary winding and its load.

Output Voltage(s):
Output voltage across the secondary winding under loaded conditions.

Peak Primary Current:
The peak current flowing in the primary winding.

Power Rating:
Maximum power transformer is expected to process.

Primary Inductance:
Inductance of the primary winding.

Pulse Repetition Rate: Time from start of a pulse to the start of the next pulse.

Pulse Duration:
The amount of time the pulse is on.

SMT Mounting:
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.

Thru Hole:
Component is manufactured with pins that mount the device through holes in the circuit board which are soldered.

Turns Ratio:
The ratio of the number of primary turns to the number of secondary turns expressed as Np:Ns.
