IRC TT HFR-PAT4556WLF-50R0-3A High frequency surface mount attenuator Datasheet

High Frequency
Surface Mount Attenuators
IRC Advanced Film Division
PAT-W
• RoHS Compliant
• 10GHz operation
• ±50ppm/°C absolute TCR
• Wrap Around 100% Sn Terminations
• 50Ω impedance available in 2 chip sizes available
The PAT-W series high performance chip attenuator provides
excellent high frequency performance at power ratings up to 500mW.
The wrap-around construction provides reliable low cost, surface mount
assembly. Long term operational stability is achieved from the thin film construction. Typical uses include
applications in medical, industrial, and communications.
