Abstract
The resistor 5 is a print-formed body including a meandering shaped first region 8 connected to the first front electrode 3 and a second region 9 connected to the first region 8 via a linking portion 10 and connected to the second front electrode 4. The first region 8 is provided with an I-cut shaped first trimming groove 11 and the second region 9 is provided with an L-cut shaped second trimming groove 12, and the side of the second region 9 positioned in the direction toward which a turn portion 12b of the second trimming groove 12 extends is an oblique side 9a that inclines to approach the second front electrode 4 as it approaches the connecting portion 7.
Claims3
A chip resistor comprising:
- a rectangular parallelepiped insulating substrate;
- a first electrode and a second electrode that are oppositely disposed on the insulating substrate with a predetermined interval therebetween;
- and
- a resistor that bridges the first electrode and the second electrode, the resistor having:
- a first region connected to the first electrode and extending in a meandering shape;
- a second region connected to the second electrode;
- a linking portion positioned between the first region and the second region;
- a first trimming groove for rough adjustment, the first trimming groove being disposed in the first region to lengthen an electric current path of the resistor;
- a second trimming groove for fine adjustment, the second trimming groove being an L-cut shaped slit, including a straight portion and a turn portion, disposed in the second region;
- a connecting portion in the second region located at a diagonal position of the linking portion and overlapping the second electrode;
- and
- a substantially triangular space with the connecting portion as an apex disposed between the second region and the second electrode,
- wherein a distance between the first electrode and the second electrode is an X-direction and a direction perpendicular to the X-direction is a Y-direction, the straight portion extends in the Y-direction from, as a start point, a side located on an extension line of the linking portion, and the turn portion extends in the X-direction from a distal end of the straight portion toward the space, and
- a distal end of the straight portion does not go beyond an imaginary line connecting a shortest distance between the linking portion and the connecting portion.
