Abstract
The present invention proposes a resistor with two barrier layers covered by a protection layer, at both sides of the resistor to resist the moisture and sulphide penetration from both sides. The barrier can enhance the anti-corrosion ability of the resister. For a metallic barrier, a distance to the resistance layer and the internal electrode layer is necessary.
Claims7
A resistor comprising:
- an internal electrode layer disposed on a substrate towards each end of which the internal electrode layer stretches, and a resistance layer disposed on an axial central region of the substrate and partially overlapping the internal elect rode layer;
- a pair of barrier layers separately disposed on two opposite sides of the substrate and respectively located with a certain distance from the resistance layer and the internal electrode layer;
- a protective layer covering the resistance layer, the barrier layer and part of the internal electrode layer;
- and
- an external electrode layer disposed to cover an exposed part of the internal electrode layer and the adjacent protective layer thereof.
