1 | To order fixed inductance parts without cores, eliminate the “J08” or “J12”, e.g. 144-01. | |
2 | Inductance and Q readings taken on Boonton 260-A Q meter with 16 AWG tinned copper 1/2" long soldered along leads and bent at 90° 1/4" down from
stand offs. All inductance values greater than 0.1 µH read at recommended Q meter frequency. All inductance values below 0.1 µH calculated from readings taken at 50 MHz. |
|
3 | L min measured with core halfway out top of form. | |
4 | Q min measured at L nom at 40 MHz. | |
5 | DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator. | |
6 | Irms: Current that causes a 40°C temperature rise from 25°C ambient. Details | |
7 | Core material: Carbonyl J Core length: 142 Series - 1/4"; 143, 144 Series - 3/8". | |
8 | Taps available in 144 Series parts at 1/8, 3/8, 5/8 and 7/8 turns. | |
9 | Ambient temperature range: | −40°C to +85°C |
10 | Storage temperature range: | Component: −40°C to +85°C Packaging trays or tubes: −40°C to +80°C |
11 | Electrical specifications at 25°C. | |
Resistance to soldering heat: Wave solder only. Recommended maximum board surface temperature of 168°C (334°F) for no more than three seconds. Pre-heating is recommended to minimize time over the solder nozzle. Refer to Soldering Coilcraft Components before soldering. | ||
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info. | ||
