The LQP03TN was a commercially available 0201-sized inductor at the time, known for its exceptional sales performance and industry-leading high Q characteristics. Currently, Murata has introduced the LQP03TQ and LQP03HQ series within the same product line, offering even higher Q values. If your application requires superior Q characteristics, it's recommended to explore these newer models. The LQP03TG is designed as a cost-effective replacement for multi-layer inductors from other manufacturers, delivering comparable Q performance at a more competitive price point. This makes it an ideal choice for applications where cost efficiency is a key consideration. There are several key differences between the LQP03TN and LQP03TG: First, the reference inductance value differs between the two models. The LQP03TN follows Murata’s long-standing approach, which takes into account the residual inductance measured on a short-circuited chip used for inductor compensation. In contrast, the LQP03TG adopts a method commonly used by other manufacturers, where the residual inductance on the short-circuit chip is considered zero. While both approaches are valid from the perspective of measurement equipment manufacturers, Murata’s method has gradually influenced the broader industry over time. Second, the internal structure design varies significantly. The LQP03TN is optimized for higher Q performance, with each design tailored to meet specific requirements. On the other hand, the LQP03TG simplifies the internal structure while maintaining Q performance that matches other industry-standard multi-layer inductors. This streamlined design allows for cost-effective production without compromising performance. Based on these distinctions, the LQP03TN is best suited for users who prioritize high-performance features, while the LQP03TG is ideal for those looking for a cost-effective alternative to multi-layer inductors.
