SRT-Microcéramique products

The high voltage radial capacitor is designed for demanding applications, standing out in severe environments and historical designs. Available in multiple dielectrics such as NPO, N2T, BX, 2X1, and X7R, it offers non-magnetic options and equivalence to most concurrent designs as per cross-reference charts. Operating within a temperature range of -55°C to +125°C, its temperature coefficient varies by model, including ±30ppm for NPO and -2200 ±350 ppm/°C for N2T. The dissipation factor for NPO and N2T models is limited to ≤ 1.10^-3 at 1Vrms and frequencies up to 1MHz or 1KHz depending on capacitance value, while X7R models feature a dissipation factor of ≤ 0.025 at 1kHz for capacitance values ≥ 100pF. Insulation resistance at 25°C/Un is rated at 105MOhm or 1000 Ohm-Farad, whichever is less, with a reduced rating at 125°C/Un. The capacitors undergo a dielectric strength test at 1.2Un for 5 seconds, with a maximum burn-in of 48 hours at 125°C at 2Un if Un <500V or 1.5Un if Un >500V.
