Naming rules and methods of chip resistors

How to read the model of the patch resistor? At the time of purchase, the label on the CD package is a long string of numbers, such as RI0603L 103JT. If you don't know the naming rules of patch resistors, you can only read 0603 and 103. Therefore, we need to know the naming rules in order to better understand and select the patch resistance we need. Let's have a look!

Let's use RI0603L 103JT to explain:

1, RI- indicates the resistance type.

(1) ri-thick film wafer resistance.

(2)RHR- high resistance thick film wafer resistor

(3) RAT-surge-resistant thick film chip resistor

(4) RHA-high precision surge-resistant thick film chip resistor.

(5)RHP- high power thick film wafer resistor

(6)RLH- high power and low resistance thick film chip resistor

(7)RHV- high voltage thick film wafer resistance

(8) RWT wide electrode thick film wafer resistance

(9) RTT adjustable thick film wafer resistance

(10) RIL-Chip Current Detection Resistor

(1 1) RMS alloy chip resistor

(12) RES-Anti-static thick film wafer resistor

(13) RLT-low temperature coefficient thick film wafer resistance

(14) rag-automobile chip resistor

(15) rcq-general quality sulfur-resistant chip

(16) rfl-special resistor for soft light bar

(17) RHT—— High-precision thin film wafer resistor

(18) rhn-high power thin film wafer resistance

(19) RTR-thin film wafer resistance

(20)ra- wafer array resistor-convex electrode

(2 1) RAA—— Resistor-convex electrode of sulfur-resistant thick film wafer array

2.0603-stands for resistance package.

( 1)0 1005

(2)020 1

(3)0402

(4)0603

(5)0805

(6) 1206

(7) 12 10

(8) 18 12

(9)20 10

( 10)25 12

3, L- indicates the temperature coefficient.

4.103-the number representing the resistance value.

103 = 10kω

1003 = 100kω

1 r0 = 1ω

5, j- represents the error of resistance.

( 1) B= 0. 1%

(2) D= 0.5%

(3) F= 1%

(4) J= 5%

6.t stands for packing method.

(1) T=T/R (weaving/winding)

(2)B = the volume in the plastic bag (volume/bag)

(3)C = boxed bulk (bulk/boxed)
