The ELJFA1R2JF is a fixed inductor manufactured by Panasonic. The '1R2' likely indicates an inductance value of 1.2 μH (microhenries). These inductors are commonly employed in various electronic circuits for purposes such as filtering, impedance matching, and energy storage.

Applications

• RF circuits
• DC-DC converters
• Matching networks
• EMI filtering

Features

• Fixed inductance value
• Small size
• High self-resonant frequency (SRF)
• Excellent Q factor (depending on series)

Benefits

• Stable and reliable inductance value for consistent circuit operation.
• Compact design, saving valuable PCB space.
• Suitable for high-frequency applications due to high SRF.
• Improved signal integrity with high Q factor versions.

Additional Details

The precise specifications of the ELJFA1R2JF, including tolerance, DC resistance (DCR), rated current, and operating temperature range, depend on the specifics of the Panasonic ELJFA series. It is crucial to consult the datasheet for the ELJFA series to acquire detailed technical information. Typically, these inductors are surface mount devices (SMD), facilitating automated assembly. They are often constructed with a ceramic or ferrite core and wound with copper wire. The ELJ series from Panasonic provides a wide selection of inductance values and current ratings to cater to diverse application needs. Proper selection involves considering inductance, current handling, DCR, and SRF for optimal circuit performance.
