The Japanese capacitor specialist Rubycon announces an upgrade of several series of SMD polymer hybrid capacitors. The PFV series (Load life: 4000h at 125 °C) has been extended by the operating voltage 80V. The PJV series (Load life: 4000h at 125 °C, High capacity) is now available with 50V and 63V operating voltages. For example, […]

KOA has extended the WK73 series by several sizes. For the WK73R (resistance ≥ 10 Ohm), three sizes are added, namely 0508, 0306 and 0204. The WK73S (resistance <10 Ohm) has been extended by size 0508. For size 0508 the rated power is spezified up to 1 Watt, for 0306 to 0.5 Watt and for […]

KOA’s new RS73-series is designed for high precision and high reliability applications by using thick film technology. With a T.C.R. down to 25ppm and a tolerance as low as 0.1%, the new RS73-series from KOA is ideal for precision designs such as high-accuracy sensing or voltage detection circuits in automotive, industrial and measuring applications, where […]

KOA now offers an advanced version of the proven SG73P-series. The Thickfilm SG73G-series is characterized by low resistance tolerance (0.5% or 0.25%) and a low TK (±50 ppm/K). This is possible because KOA optimized the resistive material and the production process. The SG73G-series has the same one-pulse characteristics as the SG73P-series. Until now three sizes […]

KOA offers now a Power up version of its proven WK73 series. Using the concept of Terminal Part Temperature, Power Ratings of 1.5 Watt (size 0612), 2 Watt (size 1020) and 3 Watt (size 1225) are possible. In every case the derating starts at 95°C. Outstanding features of this component are excellent heat dissipation characteristics […]

KOA’s UR73V-series thick film low ohm resistors are designed for current detection, especially in demanding environments. The special facedown construction makes lower resistance values with a low T.C.R. of ±75 ppm/K possible. The low T.C.R of new UR73V-series and its wide operating temperature range of -55 °C to +155 °C make it ideal for applications […]

With the new series PSJ2 and PSG4 current sensing resistors, KOA is expanding its range of Metal Plate Power Shunts. The four-pole design of the PSG4 in size 2725inch with welded copper connections makes a high current of up to 140 A possible. These low-resistance, non-inductive power resistors are available in the ohm values 0.5 […]

Now it is not necessary anymore to take a resistor in thinfilm technology if a resistor tolerance of 0,25% is used. Compared to KOA´s general purpose RK73-series, the new RK73G-series has an even better T.C.R of 50 ppm/K and its low resistance tolerance of 0,25% is ideal for precision designs. The RK73G-series in the new […]

In expansion of the WK73 series KOA offers now the WU732B. This low ohm resistor with longitudinal terminations provides at a size of 0612 and Tol. 1% a rated power of 1 Watt. The component produced in thick film technology is available in a resistance range of 10 mOhm to 100 mOhm. It is characterized […]

The SL-series from KOA is now with a power rating of 5 Watt available. The size of the SLN5 is 4528, the value range is from 5 to 9,1 mOhm (TCR 110 ppm/K) resp. from 10 to 200 mOhm (TCR 75 ppm/K). The wide temperature range extends up to 180ᵒC, the derating starts only at […]
