Low Ohm Thick Film Flat Chip Resistors from KOA

Low Ohm Thick Film Flat Chip Resistors from KOA
KOA’s UR73D-series thick film shunts are designed for current detection in power supplies, motor control and industrial automation applications. The special face down construction (mounting of the resistive element on the lower face of the component) yields low T.C.R. ratings for this series. The resistors are designed for operation from -55°C to +125°C.

Power Shunt TLRH from KOA available at Rutronik

Power Shunt TLRH from KOA available at Rutronik
The new TLRH power shunt developed by KOA is now available in the sizes 2512 inch with a power rating of 2W, 2010 inch with 1W power rating and 0805 with 250 mW power rating at distributor Rutronik. Its enhanced power rating is the result of the sandwich construction. The metal plate carrier laminated on top of the resistive layer acts as an efficient heat sink and avoids hot spots.

Ultra Flat Power Inductors from KOA

Ultra Flat Power Inductors from KOA
KOA expands its range of ultra flat power inductors. The PL inductor series with ferrite core features a maximum height of 0.5 mm. The new size 1008 inch (2520 metric) covers the inductor values from 0.33 µH up to 4.7 µH. Due to the very low ohmic DC resistance down to 0.06 Ω, the allowed current goes up to 1100 mA, despite its very small dimensions.

KOA Introduces Wide Terminal Resistor

KOA Introduces Wide Terminal Resistor
The WK73 wide terminal resistor is now available in size 1206 (3216 metric). The 90° rotated design has several advantages compared to standard resistor footprints. The 3 times higher power rating of 750mW is the most visible. It is based on the improved heat dissipation through the solder joint. The much higher terminal strength of the WK73 relates to the bigger solder pad. Additionally the lower distance between the terminals results in less expansion stress on the solder joints.

High performance power shunts for precise measurements of high currents

High performance power shunts for precise measurements of high currents
The new PSI and PSB series power shunts from KOA are particularly suited for the precise measurement of high currents. The rated power of the metal plate design resistors ranges from 3 to 6 watts at 105 °C termination temperature, and some models offer reliability benefits in high temperature and power load cycling environments by a specially designed shape of the landing pads. Typical applications comprise ECUs, inverters, and industrial automation equipment.
