Bf908r

The phrase BF908R refers to a specific N-channel depletion-type dual-gate MOS field-effect transistor (MOSFET) manufactured by NXP Semiconductors (formerly Philips) DigikeyNxp.

Product Overview & Key Specifications

The BF908R is designed primarily for high-frequency applications in the VHF and UHF bands, such as television tuners and professional communication equipment NxpAlldatasheet.

• Reverse Pinning: The "R" suffix indicates reverse pinning (SOT-143R package), which is a critical layout distinction from the standard BF908 NxpMouser.
• Performance: It features high forward transfer admittance and a low noise figure (0.6 dB at 200 MHz), making it ideal for low-noise amplification Digi-ElectronicsNxp.
• Ratings: Maximum drain-source voltage of 12V and a total power dissipation of 200mW MouserPneda.

Market Status & Trends

• Obsolescence: The BF908R is officially Obsolete and is no longer manufactured by NXP DigikeyNxp. The Last Time Buy (LTB) period ended in December 2016, and final shipments were completed in June 2017 Nxp.
• Availability Insight: Because it is essential for the repair and maintenance of legacy RF hardware, the market has shifted from mainstream distributors to the secondary "gray market" and specialized "New Old Stock" (NOS) brokers IcallinAlibaba.
• Pricing Trends: While the historical budgetary price was approximately $0.12, current secondary market prices range from $0.18 to over $1.00 per unit, reflecting a premium for discontinued inventory NxpAlibaba.
