CRD Current regulative diode - 20 mA pre-wired 1 piece

Description

CRD- Current regulative diode pre-wired
Input voltage 10 V - 40 V direct voltage
Constant current 20 mA, tolerance +- 20%.

Type SOD-123 - similar to 0805

Ideal for replacing series resistors in LED circuits. A constant current flows through the diode regardless of the applied voltage. Simply replace the series resistor with the CRD diode in correct polarity. LED brightness is largely independent of the supply voltage.

The CRDs can be connected in parallel, then the currents add up.

e.g.: Current 15 mA = CRD 10 mA connected in parallel with CRD 5 mA

wired with enamelled copper wire 0.15mm, polarity:

Positive pole: pink wire,

Minus pole: black wire

We can also wire with 0.1mm enamelled wire
