The CS0402-47NK-S is a multilayer chip inductor manufactured by Chilisin. It's designed for high-frequency applications and is characterized by its small 0402 (0.4mm x 0.2mm) form factor, making it ideal for miniaturized electronic devices where space is a constraint. The inductor is used primarily for impedance matching, filtering, and tuning in RF circuits.

Applications:

• RF impedance matching
• RF filtering
• Wireless communication circuits
• Mobile phone circuits
• Bluetooth modules

Features:

• Small 0402 package size
• High self-resonant frequency (SRF)
• Excellent Q-factor
• Tight inductance tolerance
• Multilayer construction

Benefits:

• Enables miniaturization of electronic circuits
• Provides stable performance at high frequencies
• Minimizes signal loss and improves circuit efficiency
• Ensures consistent electrical characteristics
