Typical Applications & Why This Part Fits

• RF front-end modules: The 270 nH inductance and low DCR of 4.94 Ω enable efficient signal filtering with minimal insertion loss in transceiver chains.
• DC-DC converter output filtering: 110 mA current handling and tight inductance tolerance suit post-regulation stages in portable devices.
• Antenna matching networks: The SMD package and stable inductance from 100 MHz to several GHz ensure reliable impedance transformation.

Key Features & Advantages

• Stable inductance over frequency: The monolithic ceramic structure maintains 270 nH ±5% across a wide frequency range, critical for consistent filter performance.
• Compact SMD form factor: Saves PCB real estate compared to wire-wound inductors while offering a 4.94 Ω DCR that balances efficiency and size.
• High self-resonant frequency: Enables operation well into the UHF band, making the LQG15HSR27J02D ideal for 2.4 GHz ISM-band applications.
