Title:
RESISTOR
Document Type and Number:
Japanese Patent JP2022096873
Kind Code:
A
Abstract:
To suppress resistance value fluctuations due to temperature while ensuring good sound quality.SOLUTION: A carbon film 4 as a resistor and a metal film 5 as a resistor are formed on a substrate 3 made of porcelain or glass. These films are provided with a spiral slit 6 for adjusting a resistance value. Metal caps 2 are provided at both ends of the substrate, and lead wires 1 extend outward from the respective caps 2. An exterior coating 7 is applied to the surface of the resistor except the lead wire 1.SELECTED DRAWING: Figure 1
