The new PSV series from Rubycon combines long life at high temperature with a constant ESR and high ripple currents. The Japanese capacitor specialist Rubycon guarantees a lifetime of 3000 hours for the PSV series at an ambient temperature of 135⁰C. The low ESR is largely stable over the entire temperature range. The ripple currents […]

KOA offers its proven High-Power series BGRV, BWRV and BSRV now also completely with automotive certification. The wirewound (BGRV, BWRV) or metal oxide coated (BSRV) power resistors in ceramic housing are available with different connection styles. The component is suitable for high switching currents and as charging or discharging resistor. Rated powers between 3W and

The KOA industrial standard Thin Film series RN73 becomes RN73R. But not only the designation changes, some technical parameters also improve significantly. For example, derating in the context of Rated Ambient Temperature only starts at 85°C, compared to 70°C before. Furthermore the long-term stability during the Load Life Test (1000h) improves to ±0.1%, compared to

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
