TCP-4112UB-DT

Product Overview

TCP-4112UB-DT from onsemi is a RF tunable capacitor / antenna tuning IC used in RF, microwave or wireless front-end designs. This product detail focuses on practical RF function, operating range, control/interface requirements and sourcing relevance for engineering and procurement teams.

The exact suffix should be matched against the original BOM because RF behavior can depend on package, die or reel option, control logic, bias network and qualified operating conditions.

Key Features

• Manufacturer: onsemi
• Part Number: TCP-4112UB-DT
• Device Type: RF tunable capacitor / antenna tuning IC
• RF Function: Digitally or voltage-controlled RF tunable capacitance for antenna/aperture matching
• Application Band: Mobile RF antenna tuning and impedance matching across cellular or wireless bands
• Capacitance Function: Model-specific tunable capacitance value encoded by TCP series and suffix
• Control Interface: Digital or bias/control interface depends on TCP family and package
• Package / Case: manufacturer package/orderable suffix should be verified against the original BOM
• System Role: Improves antenna match, efficiency and band coverage under changing use conditions
• Design Notes: Confirm capacitance range, voltage rating, control logic and RF ESD layout for the exact TCP model.

Applications

Smartphones, IoT radios, LTE/5G front ends, antenna matching networks and tunable RF filters.

Sourcing support for antenna-tuning designs where capacitance range and package revision must match the RF layout.

Quality & Sourcing

Antrex Electronics can support sourcing for TCP-4112UB-DT through available stock checks, BOM consolidation and alternative-lot review. For RF and microwave parts, package marking, date code, MSL handling and original-label condition should be checked before shipment.

For project builds, repair support or shortage coverage, Antrex Electronics can coordinate visual inspection, package verification and third-party testing when required. This helps buyers manage risk when sourcing discontinued, legacy or hard-to-find RF ICs and modules.
