SV09AC474KAR

The SV09AC474KAR is a high voltage multilayer ceramic capacitor (MLCC) from Kyocera AVX, part of the SV series designed for demanding high voltage applications. It offers a capacitance of 0.47 µF with a tolerance of ±10% and a rated voltage of 1000V (1kV). The X7R temperature coefficient ensures stable performance with a capacitance change of ±15% over the operating temperature range of -55°C to +125°C.

This radial leaded capacitor features a conformal epoxy coating that provides high insulation resistance and high dielectric strength, minimizing the risk of arc flashover. The internal design reduces electric field stresses, leading to lower partial discharge activity and enhanced long-term reliability. The component exhibits low ESR at high frequencies, making it suitable for snubber circuits in high frequency power converters, resonators in switch-mode power supplies (SMPS), and high voltage coupling or DC blocking applications.

The package is a through-hole radial format with straight leads and a lead spacing of 17.10mm (0.673"). The body dimensions are 19.60mm length, 5.08mm width, and 18.30mm height. General specifications for the X7R dielectric include a dissipation factor of 2.5% maximum, insulation resistance of 100K MΩ minimum at 25°C, and a dielectric strength of 120% of rated voltage for 5 seconds.
