AKANE:OHM have released High Current Shunt Resistor “APS” Series for high current precise measurement circuits in such as automobiles and industrial equipment’s.

As circuits have higher performance, higher power, and higher safety in recent years, the APS Series is ideal for current control and current detection of overcurrent protection circuit in automobiles and industrial equipment’s.

Since the APS series has low resistance, high power rating, and low TCR, it enables more accurate current detection.

Background

As devices have higher performance, higher power, and higher safety in rent years, shunt resistors are also required to have the following performance:

・Lower resistance:  power saving of circuit

・Higher power rating:  support for higher in-circuit current

・Stabilization:  stable current detection over a wide temperature range

Shunt resistors are used for current control, overcurrent detection, and current monitoring.

<Main applications>

◎Battery charging:  adjustment of charging current (charging current monitoring, overcharging protection)

◎LCD backlight:  backlight current monitoring

◎Brightness adjustment:  brightness control by monitoring current flowing through LED

◎Disconnection and short circuit detection: monitoring of lamp current to prevent disconnection and short circuit of in-car interior lights

◎DC motor:  current detection and overcurrent protection for precise rotation control

◎Inrush current prevention: prevention of inrush current in power supply line

As devices have higher performance, higher power, and higher safety in rent years, shunt resistors are also required to have the following performance.

<Technology Trends>

◎Lower resistance:  power saving of circuit

◎Higher power rating:  support for higher in-circuit current

◎Stabilization:  stable current detection over a wide temperature range

We have released a new series “APS” that meets these needs and has a low resistance and high power rating.

New product overview

High Current Shunt Resistor “APS series” is ideal for the following circuits.
