SMT Chip Resistor and Capacitor Identification Methods
Identification methods for SMT chip resistors and capacitors
1. Check the color - All chip capacitors have no screen printing, the production process is completed by low-temperature sintering, and it is impossible to print words on the surface. The colors are mostly bluish-gray.
2. Check the markings - The symbol for a chip capacitor in a circuit is "C", and the symbol for a chip resistor is "R".
3. Check the screen printing - Those with screen printing are usually resistors.
Identification methods for SMT chip capacitors and inductors
1. Check the color - Usually, only high-precision chip tantalum capacitors are black, while others are generally not black. Chip inductors are mostly black.
2. Check the model code - Chip inductors start with L, and chip capacitors start with C. Judging from the shape, if it is round, it should be an inductor.
3. Check the internal structure - Find similar components, and possibly disassemble the components to check their internal structure. Those with a coil structure are chip inductors.
Identification methods for SMT chip resistors and inductors
1. According to the shape - Inductors have polygonal shapes, while resistors are mostly rectangular. Especially when round, it is usually identified as an inductor.
2. Measure the resistance value - The resistance value of an inductor is relatively small, and the resistance value of a resistor is relatively large.
