Chip Resistor
CHIP resistors consist of a deposited resistive paste on ceramic body and two wrapping end of the resistor to wave solding.
FEATURE
- The resistive layer is covered with a protective coating to assure mechanical and environmental integrity.
- Excellent mechanical strength and electrical stability due to special electrode construction.
- Free from troubles at placement due to accurate and uniformed physical dimensions.
- Low TCR available: 100ppm, 50ppm, 25ppm
