Chip Current Detecting Resistors (CS)

Thick Film Chip Current Detecting Resistor (CS) Introduction

Token Chip Current Detecting Chip Resistor (CS) save space and weight.

< >
  • Chip Current Detective Resistors - CS Series

Token Electronics has launched the CS series, a family of ultra small low value surface mount curren sensing resistor. These smaller sizes save space on the circuit board, allowing the production of smaller and lighter products.

The new series complements Token's existing LRC Series, offering metal resistive film on ceramic construction but providing increased choice for product designers in the form of more smaller sizes options of 0201, 0402, 0603, 0805, 1206, 2010, 2512, 1225, 3720, 7520, and 0612.

Designed for current detecting in power electronic systems, the fully RoHS compliant CS series is suitable for a range of applications including the monitoring of power usage and battery life; and provision of output protection for power supplies; as well as for a range of consumer and automotive products such as satellite navigation, handheld PDAs and digital set-top boxes.

The series offers ohmic values as low as 1mΩ to minimise power consumption and has an ambient temperature range of -55°C to +155°C.

Exhibiting a resistance range up to 8000mΩ and excellent heat dissipation qualities, the series offers designers enhanced power handling capabilities and protection from the threat of localised heating, resulting in the production of a more energy efficient product.

As demand continues to grow for reduced size, handheld and portable devices operating at low voltages, designers will look to manufacturers to produce smaller and smaller current sense resistors. Token expects that demand for its latest range of small size resistor will be high. Contact us with your specific needs.
