 General Information

Your Current Options - Token Current Sense

As the world becomes more and more technology-driven, the uses for current sensing components will

continue to increase. The need for even lower resistance value ranges is already becoming evident, as

is the need for these resistors to handle more power. The industry-wide trend is the emergence of

smaller and smaller products.

Token Electronics offers a wide variety of current sensing products from the industry to military

standards, such as current sense in Thin-Film / Thick-Film Technology, Bare Element Resistors, and

Open Air Shunts. This enables Token to present an astounding number of possible solutions for any

circuit design needs.

Applications of Current Detecting Components

Token's TCS and CS Series unique form factor provides automotive designers with several advantages.

Both TCS and CS Series are ideal for applications involving window lift motors, fuel pump systems,

seat belt pretensioners, and pulse width modulator feedback.

The wider resistive element and lower resistance enables higher current to pass through the device.

Token's LRC ultra low Ohmic metal strip chip series provides the inherent ability to flex slightly and

offers stress relief during extreme temperature cycling on typical or metal substrates. This LRC series

is suitable for switch power supply applications (DC-DC Converter, Charger, and Adaptor) and power

management of monitor.

The open air design of bare element resistor LRA and LRB Series provide a far cooler operation by

allowing more air flow under the resistive element to keep excess heat from being transmitted to the

PC board. They are suitable for high power AC/DC detection of power supply circuit.

Token axial moulded BWL series provides power rating up to 10 watts and lower resistance 0.005Ω, is

ideal for all types of current sensing applications including switching and linear power supplies,

instruments and power amplifiers.

Token standard current sensing components can be replacement for Vishay, IRC, Ohmite, KOA, Yageo

devices with fast delivery and more competitive price. Contact us with your specific needs.
