1761 / 1761V

Variable Reluctance 150Ω Earphone

The 1761 earphone (NOT hearing aid compatible) is a physical, electrical and acoustical replacement for the Western Electric LA or LB in standard handsets.

This element is available with an optional click-suppressing varistor (P/N 1761V). The purpose of the varistor is to protect the users' hearing by limiting the maximum output of the earphone element, and is a UL requirement for some applications.

Elements are available in a variety of custom impedances that may require minimum purchase quantities and varying lead times - contact our sales department for more information and pricing.
