04025U1R0BAT2A

The Kyocera AVX 04025U1R0BAT2A is a surface-mount multilayer ceramic capacitor (MLCC) from the U Series, designed for ultra low equivalent series resistance (ESR). It offers a capacitance of 1 pF with a tight tolerance of ±0.1 pF and a rated voltage of 50V. The capacitor uses a C0G (NP0) dielectric, providing a temperature coefficient of 0±30 ppm/°C over the operating range of -55°C to +125°C.

This component is optimized for RF, microwave, and high-frequency applications where low ESR is critical for signal integrity and efficiency. The 0402 (1005 metric) package size enables compact PCB layouts, and the plated Ni and Sn terminations ensure reliable solder joints. Typical applications include filtering, tuning, and coupling circuits in wireless communication systems.

The part meets RoHS3 and lead-free requirements, and is available in 7-inch reel packaging for automated assembly. For design engineers, the insulation resistance is guaranteed at 10^12 Ω minimum at 25°C and 10^11 Ω at 125°C, with a dielectric withstanding voltage of 250% of rated WVDC.
