C. Color coding:

1.

Parts are marked with 3 color dots. The table at below shows the significance of each color.

2.

Dots 1 and 2 indicate the inductance in nano-Henries.

3.

Dot 3 indicates number of zeroes to be added.

D. General Information:

1.

P/N: 1812CP-xxx_, “1812CP” = Size Type, “xxx” = Inductance, “_” = Tolerance.

2.

Tolerance “_” : K: ± 10%, J: ± 5%, G: ± 2%.

3.

Small and lightweight surface mounting type.

4.

High Q at high frequency & High self-resonance frequency.

5.

For 15ºC Temperature Rise at 25ºC ambient.

6.

Inductance & Q measured with HP4291B Impedance Analyzer.

7.

SRF measured using the HP8720D or HP8753E Network Analyzer.

8.

DCR measured using the 16502 milliohm meter.

9.

Operating temperature: -40

°C to +125ºC.

10. This series has no color code due to the size is small.
