Overview
The Coilcraft 0302CS-9N2XJRW is a surface-mount RF inductor from the 0302CS series, designed for high-frequency applications. It features a nominal inductance of 9.2 nH with a tolerance of ±5%. The component operates at a test frequency of 250 MHz and exhibits a maximum DC resistance of 115 mΩ. It supports a maximum DC current of 690 mA and utilizes SMD/SMT termination technology.
Feature Summary
- Exceptionally high Q factor for its physical size
- Very high self-resonant frequencies suitable for GHz bands
- Compact 0302CS footprint, 20% smaller than 0402CS series
Applications
- RF front-end matching networks
- High-frequency signal processing circuits
- Wireless communication modules
Procurement Notes
Verify the specific suffix JRW against official Coilcraft documentation to confirm exact tolerance and packaging specifications. Ensure compatibility with standard SMD reflow processes. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and compliance certifications such as RoHS before finalizing procurement orders.
Selection Notes
Select this component when space constraints require a footprint smaller than the standard 0402CS series while maintaining high performance. The 9.2 nH value is suitable for impedance matching in high-frequency circuits. Consider the 690 mA current rating and 115 mΩ DCR for power handling requirements in compact RF designs.
Part Context
This part belongs to the 0302CS series of ceramic core chip inductors manufactured by Coilcraft. The series is characterized by high Q factors and high self-resonant frequencies. The 0302CS package offers a reduced form factor compared to larger series, making it ideal for dense PCB layouts in modern electronic devices requiring precise RF characteristics.
Replacement Considerations
Consult official Coilcraft substitution guides for verified alternatives. Generic cross-references may not match the specific Q-factor or self-resonant frequency characteristics required for critical RF applications.
