Four-terminal

Open Air Resistors

Token’s Open Air Four-terminal resistors (LRD)

tackle current sensing applications

Preview

Always preferred in current sense applications,

Token’s LRD Series range is available in the

1W, 3W, 5W, 7W and 10W packages,

resistance values down to 0.001 ohm,

with tolerances as tight as 0.50% and

TCRs of 50ppm standard.

The Kelvin (four-terminal) conﬁguration

enables current to be applied through two

opposite terminals and a sensing voltage to

be measured across the other two terminals,

eliminating the resistance and temperature

coefﬁcient of the terminals for a more accurate

current measurement.

With up to 10W power rating and TCRs as low as 50ppm/°C, the LRD Series resistors deliver excellent

performance, making them ideal for a variety of applications. The resistor is constructed using a low-resistance,

low-inductance, high-impulse proprietary metal element that gives the device its extended power and temperature

ratings.

Continually upgrading its resistors to take advantage of modern technologies and manufacturing methods, Token

is now able to offer complete ranges of products which meet the RoHS requirements and in addition to detailing

these, the component selector also provides designers with a comprehensive selection of application notes.

The LRD devices can be manufactured to custom length/width for use as a current shunt. Token will also produce

outside these speciﬁcations to meet customer requirements. Contact us with your speciﬁc needs.
