IRC RC Series Fixed Resistor Metal Film 0.25W 37400 Ohm
Introducing the IRC RC Series Fixed Resistor, a high-precision metal film resistor designed for demanding electronic applications. Manufactured by IRC/TT ELECTRONICS in Great Britain, this resistor offers exceptional stability, low noise, and tight resistance tolerance, making it ideal for precision circuitry.
The resistor body is constructed by depositing a metal film onto a ceramic former, with nickel-plated steel caps and welded termination wires. The resistor is adjusted via a helical cut in the film and protected with epoxy coating. Terminations are 100% tin-plated over copper wire, meeting IEC standards for solderability and solvent resistance. The resistor body and markings are resistant to typical industrial cleaning solvents.
Additional Information
