Brooks Instrument GF125 Series Metal-Sealed Mass Flow Controller
About this part
GF125C-105883 is a configured Brooks Instrument GF125/GF100-family metal-sealed thermal mass flow controller for semiconductor, MOCVD, thin-film, and high-purity gas delivery. Official Brooks GF100/GF120/GF125 documentation covers the platform, performance context, materials, communication families, MultiFlo support, and installation guidance, but no verified official one-part specification for GF125C-105883 is currently available Stored Sonisys auction history and listing evidence associate this exact configured identifier with N2 860 SCCM context and separate 5%PH3/He 700 SCCM / AMAT 0190-49894-02 context; verify gas, full-scale range, valve state, fitting package, communication option, and any customer or OEM marking from the physical unit label before reuse
Configurations vary. Verify the exact unit before choosing a replacement.

Applications
Application domain
Semiconductor, MOCVD, thin-film, and high-purity process gas flow control applications requiring an all-metal flow path
Performance
Family accuracy context
Brooks GF100/GF120/GF125 documentation lists +/-1% of set point above 35-100% and +/-0.35% full scale over 2-35% based on factory N2 calibration for applicable analog and DeviceNet configurations
Family repeatability context
Brooks GF100/GF120/GF125 documentation lists repeatability and reproducibility of +/-0.15% of set point from 5-100% and +/-0.015% full scale from 2-5%
Family settling-time context
Brooks GF100/GF120/GF125 documentation lists normally closed valve settling-time bins from 300 ms to less than 700 ms across documented flow bins, depending on configuration
Pressure transient insensitivity
Brooks GF100-family documentation identifies pressure transient insensitivity as a feature for applicable configurations; PTI availability and range limits should be verified by the full configured code
Materials
Wetted path standard
Brooks GF100/GF120/GF125 documentation describes SEMI F20 HP compliant wetted materials
Wetted materials context
Brooks GF100/GF120/GF125 documentation lists wetted material context including 316L VIM/VAR, Hastelloy C-22, 316L stainless steel, 304 stainless steel, KM-45, and PCTFE on optional zero leak-by valve configurations
Leak integrity
External leak integrity
Brooks GF100/GF120/GF125 data-sheet table lists external leak integrity of 1 x 10^-10 atm cc/sec helium
Controls
Communication interfaces
Brooks documentation provides Analog/RS-485, DeviceNet, RS485 L-Protocol, EtherCAT, and EtherNet/IP family context; the actual interface depends on the configured electronics option
Flow
Gas/range programmability
MultiFlo gas and range configurability is documented for supported GF100-family devices
Ratings
Operating temperature context
Brooks GF100/GF120/GF125 documentation lists a 10 C to 50 C operating temperature range for documented family configurations
Configuration
Configured-unit rule
Gas, full-scale flow range, valve or meter configuration, fitting package, electrical connector, communication protocol, display, surface finish, seal package, and customer/OEM options vary by full configured model code
Observed configuration
Stored auction gas/range combinations
Stored exact auction evidence includes N2 860 SCCM context and separate 5%PH3/He 700 SCCM context for GF125C-105883; use these as observed listing context and verify against the physical label
Stored listing observations
Stored exact auction evidence reports GF125CXXC wording and AMAT 0190-49894-02 context for GF125C-105883; use these only as observed identity and configuration context
