Terminology & Glossary
Flip Chip Resistor
An unencapsulated resistor chip on which bead-type leads terminate on one face to permit “flip” (face
down) mounting of the resistor chip by contact of the leads with interconnective circuitry.
Hot-Spot Temperature
The maximum temperature measured on the resistor due to both internal heating and the ambient operating
temperature.
Low Profile
Components designed with “lower than standard heights”, to save space and allow clearance when mount-
ed on PCBs.
Maximum Working Voltage
The maximum specified voltage that may be applied across a resistor.
PPM
Parts per million. The terminology used when describing the temperature coefficient.
Screen
The process of printing a network pattern of thick-film ink or paste onto a substrate by means of a squee-
gee applied to a photo-etched wire-mesh “silk screen” or metal mask.
Current Shunt Resistors
Current shunt resistors are low resistance precision resistors used to measure AC or DC electrical currents
by the voltage drop those currents create across the resistance. Sometimes called an ammeter shunt, it is a
type of current sensor.
SMT/SMD
Surface-mount technology/surface-mount device.
Zero Ohm Resistors
Products that look like resistors, but actually have no resistance (very very low resistance) and instead
perform as jumpers.
