Chip Resistorswww.passivecomponent.comThick Film Low Ohm/Power Low Ohm Chip ResistorsFunction For Low Ohm Chip ResistorsThe low ohmic resistors are used to sense output current in power supply,automotive and engine control management system, and other powersensing application. As shows in figure below, the typical function of lowohmic (power) chip resistor is to be a current sensor (Rsense) to generatethe sensing voltage (Vs) for the purpose of feedback control when outputcurrent (Io) passed on it. The sensing voltage be treated as a signal to triggerthe switches (CMOS) ON/OFF duration so that to monitor and/or adjust theoutput current from inductor.Simplify to say,Vs = I0 x Rsense.In general case, this feedback voltage is setting around 100mV forconsidering both on power saving and noise robustness. To sense a 5ampere average output current, the Rsense resistance value therefore berequired as 100mV / 5A = 20 m, the power dissipation will be :P = I 2 x R = 5A 2 x 20m = 0.5 WattA low ohmic chip resistor with a power rating of 1.0 watt is recommended onthis application in case the power safety margin is taken into account.Series No. WW25X WW20X WW18X WW10X WW12X WW08X WW06X WW04XSize Code 2512 (6432) 2010 (5025) 1218(3248) 1210(3225) 1206 (3216) 0805 (2012) 0603 (1608) 0402 (1005)Resistance Tolerance ±5%, ±1%Resistance Range 0.100 0.976TCR (ppm/ºC)Detailed TCR please refer to specific data sheetsMax. dissipation @ Tamb=70ºC 1 Watt 0.5 Watt 1 Watt 1/3 Watt 1/4 Watt 1/8 Watt 1/10 Watt 1/16 WattMax.

Chip Resistorswww.passivecomponent.comStorage and Handling Conditions:1. Products are recommended to be used up within one year. Check solderability in case shelf life extension is needed.2. To store products with following condition:Temperature : 5 to 40°CHumidity : 20 to 70% relative humidity3. Caution:a. Don’t store products in a corrosive environment such as sulfide, chloride gas, or acid. It may cause oxidization of electrode, which easily beresulted in poor soldering.b. To store products on the shelf and avoid exposure to moisture.c. Don’t expose products to excessive shock, vibration, direct sunlight and so on.Figure.
