12101A182JAT4A

The 12101A182JAT4A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a leading producer of passive electronic components. This component belongs to the 1210 case size family, which refers to its physical dimensions in metric notation (12mm × 10mm). Multilayer ceramic capacitors like this one are fundamental passive components used extensively in modern electronic equipment to store electrical charge, filter signals, and stabilize voltage supplies. Multilayer ceramic capacitors serve critical functions across virtually every industry segment that relies on electronic circuitry. The 1210 package size positions this component in the mid-range of ceramic capacitor offerings, providing a balance between capacitance density and ease of assembly. These capacitors are commonly specified in power supply circuits, audio equipment, telecommunications infrastructure, consumer electronics, automotive systems, and industrial control boards. Engineers select MLCCs in this size class when they need moderate to higher capacitance values while maintaining compatibility with standard surface-mount assembly processes. The "JAT4A" designation in the part number conveys specific electrical and environmental characteristics of this capacitor. The J-code typically indicates the voltage rating class, while the remaining alphanumeric code specifies the dielectric material, capacitance tolerance, and temperature coefficient. This particular part is designed to meet reliability requirements suitable for both commercial and industrial applications where consistent performance across temperature variations is important. One key reason an engineer might specify the 12101A182JAT4A over alternative capacitors includes its established track record within AVX's product ecosystem. AVX capacitors are known for consistent manufacturing quality and reliable performance in demanding environments. The 1210 form factor is widely adopted across the industry, meaning it integrates well into established PCB designs and production workflows. Additionally, this part number likely offers a specific balance of electrical characteristics—such as voltage rating, capacitance value, and temperature stability—that match particular circuit requirements that smaller or larger case sizes cannot adequately fulfill. For designers working on revision cycles or new equipment development, the specificity of this part number ensures that electrical behavior will remain consistent across production batches and time. Engineers appreciate the predictability this brings to circuit performance, particularly in applications where capacitor aging or thermal drift could compromise system operation. Whether you're designing industrial control equipment, consumer products, or specialized instrumentation, the 12101A182JAT4A represents a proven, widely-compatible solution for capacitive energy storage and signal conditioning requirements in mid-range applications.
