Chip Resistor - Trimmable
■
INTRODUCTION
Chip resistors are general passive component which is useful for derating voltage, current
controlling in circuit and surface mounting is available. User trimmable chip resistors are
manufactured and the end user can calibrate the resistor value of the part using laser trimmer.
Production is increasing with demand for small size & light weight of set product. We provide
ultra-small, high-reliability, high-stability resistors.
■
FEATURE AND APPLICATION
●
Feature
- Can be trimmed after SMD.
- Protective coating for resistor and YAG laser trimming.
- Both flow and reflow soldering are applicable.
●
Application
- Precision circuit where reliable tolerance in module by trimming.
- Available for User's exact resistance.
