FPA250 Thick Film Power Resistors
Due to a Non-Inductive design these elements are
ideally suited for high frequency and pulse load
applications. the FPA250 is available connected as 2
terminals or 4 terminals, in parallel or series.
• Non Inductive Performance for HF Applications
• Power Applications 100W to 600W
• Very Good Power/Volume Ratio
• RoHS Compliant
