1. Product Overview:

· The document describes two series of tunable/adjustable inductors: the 150 Series and the 146 Series.
· Both series have versions with and without a shield:
* Unshielded: Indicated by "J08" in the part number (e.g., 150-01J08).
* Shielded: Indicated by "J08SL" in the part number (e.g., 150-01J08SL).

2. Part Numbering & Ordering:

· To order fixed inductance parts *without* the core, you eliminate the “J08” suffix (e.g., order 150-01L instead of 150-01J08).

3. Technical Specifications (General):

· Core Material: Carbonyl J.
· Operating Temperature Range: -40°C to +85°C.
· Electrical Specifications: Based on measurements at 25°C.
· Taps: Available on the 150 series at 1/8, 3/8, 5/8, and 7/8 turns.
· Measurement Method: Inductance and Q readings are taken using a Boonton 260-A Q meter with a specific test setup (16 AWG tinned copper, 1/2" long, bent at 90°).

4. Key Data in Tables (Example Data - Summarizing a few lines):

Part Number	Series	Shielded?	L (µH) Range	Q (Typical)	SRF (MHz)	Irms (A)
150-01J08	150	No	42.5 - 44.5	72	50	11.0
150-01J08SL	150	Yes	42.5 - 44.5	72	50	11.0
146-07J08	146	No	155 - 194	68	430	15.6
146-07J08SL	146	Yes	155 - 194	68	430	15.6

*(Note: The tables contain a lot of data - this is just a sample to show the format.)*

5. Important Notes:

· Lmin is measured with the core halfway out of the form.
· Irms represents the average current required to produce a 40°C rise above 25°C ambient.
· SRF represents Self-Resonant Frequency.
