Description and Introduction

a Phase-Dimmable, Primary-Side Regulated LED Driver # Introduction to the NCP21WF104J03RA Electronic Component  

The **NCP21WF104J03RA** is a high-performance **multilayer ceramic capacitor (MLCC)** designed for a wide range of electronic applications. With a capacitance value of **100nF (0.1µF)** and a voltage rating of **100V**, this component is well-suited for filtering, decoupling, and energy storage in circuits requiring stable performance under varying conditions.  

Featuring a **X7R dielectric**, the NCP21WF104J03RA offers **moderate temperature stability**, maintaining its capacitance within **±15%** over a temperature range of **-55°C to +125°C**. Its **surface-mount (SMD)** design ensures compatibility with modern PCB assembly processes, making it ideal for compact and high-density circuit layouts.  

The component's **0603 package size (1.6mm x 0.8mm)** allows for efficient space utilization without compromising reliability. Additionally, its **lead-free and RoHS-compliant** construction aligns with environmental regulations, making it suitable for use in consumer electronics, automotive systems, industrial controls, and telecommunications equipment.  

Engineers value the NCP21WF104J03RA for its **low equivalent series resistance (ESR)** and high-frequency performance, ensuring minimal signal loss in demanding applications. Whether used in power supply filtering or signal conditioning, this capacitor delivers consistent performance in a compact, durable form factor.
