1808AC103JAT1A

The AVX 1808AC103JAT1A is a multilayer ceramic capacitor (MLCC) in the compact 1808 surface-mount package. This component is designed for use in applications requiring reliable energy storage, filtering, and decoupling in electronic circuits across industrial, consumer, and telecommunications equipment. Multilayer ceramic capacitors are fundamental passive components used to stabilize power supplies, filter high-frequency noise, and couple or decouple AC signals in virtually all modern electronic systems. The 1808 package format—measuring 1.8mm by 0.8mm—offers a balanced combination of compact size and practical capacitance density, making it suitable for space-constrained PCB layouts while maintaining accessible soldering characteristics for automated assembly. The "AC" designation in this part number indicates this capacitor is rated for alternating current applications or general AC use, distinguishing it from DC-specific variants. AVX manufactures this component using advanced MLCC technology that combines multiple ceramic dielectric layers with internal metal electrodes to achieve stable capacitance values in a minimal footprint. This construction method allows for consistent performance across temperature ranges typical in industrial environments. Engineers frequently specify the 1808 package class for applications where mid-range capacitance values are needed without resorting to larger physical packages. This size sits between smaller 0603 packages and larger formats, offering flexibility in design decisions. The AVX brand represents established reliability in military, aerospace, medical device, and industrial automation sectors, where component consistency and long-term availability are critical considerations. Common application areas for 1808 MLCCs include power supply rail decoupling, high-speed digital circuits, RF filtering, timing circuit stabilization, and sensor signal conditioning. Industrial equipment such as motor drives, power converters, control modules, and diagnostic instruments routinely incorporate capacitors of this package class as part of their core filtering and stability networks. When selecting this specific part, engineers benefit from AVX's quality control standards and established long-term manufacturing continuity. The 1808 form factor represents an optimal choice for designs requiring proven ceramic capacitor performance without the assembly complexity or cost of larger packages, while providing superior electrical characteristics compared to smaller alternatives when higher capacitance is necessary. For applications in harsh industrial environments or equipment subject to thermal cycling, vibration, or electrical stress, the 1808AC series from AVX offers a well-established solution that integrates straightforwardly into standard surface-mount assembly processes.
