CSR

Current Sensing Resistor (CSR) is placed in a current circuit and is used to monitor the current flow by measuring the voltage drop across it. The current sensor outputs a voltage that is proportional to the current through the measured path. According to Ohm’s Law V=I*R to calculate the current flow. CSR is often associated with IC, MOS and designed in the PCM protection board to become one of the important parts of the Lithium battery module.

ICP CSR Series：

1.Metal Film Resistor: CCS,CCSH,TCS
2.Metal Foil Resistor: MCS,MCSE,MCSH,MCSL
3.Metal TypeShunt Resistor: MCSS

CSR Trend:

Due to power system design trendto more higher power ratingorsmaller size application, the new generationcurrent sensor resistor is requested as follows
a. Low resistance
b. Handling more power
c Higher current capability
d. Smaller size for portable device
e. Tight resistance tolerance
f. Low TCR (Temperature Coefficient of Resistance )
g. Low thermal EMF
h. Green and RoHS product

ICP CSR Advantage:：

1.ICP is the few companies successfully provide the most smallest chip current sensor resistor size 0402(1/8W) for smart phone and pad battery PCM module.

2.ICP is the few companies by using elector beam welding technology to make metal shunt resistor with high power (3W~10W) and low resistance(0.2mΩ~5mΩ) CSR especially suitable for motive battery module in battery tool, e-bike, e-motor, vacuum cleaner, EV, ESS, PV inverter, UPS related fields.

3.ICP can quickly response to make customized device especially in smaller resistor value, smaller size bigger power rating and special shape.

4.ICP provide excellent quality and attractive price to customer.
