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.
0 = Black
1 = Brown
2 = Red
3 = Orange
4 = Yellow
5=Green
6=Blue
7 = Violet
8 = Gray
9 = White
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.
11. Inductance and Current Range: From 82 nH (1500mA) to 1200 nH (480 mA)
12. SRF: From 230 MHz to 860 MHz
13. MSL: Level 1.
E. Applications:
1. Game Consoles
2. Set Top Boxes
3. Cables Modems
4. Computers
5. Mobile Communication Devices (Cell Phones, Radios, etc.)
6. RF Filters
