NOTES:
• Operating temperature -55°C to +125°C
• Current rating is based on a 90°C
ambient; 35°C max temperature rise
• Weight maximum 0.50 grams
• DWV 200 Vrms @ sea level
80 Vrms @ 70,000 feet
• Supplied on Tape & Reel: 2000 parts on
7 inch reel
* Measured at 1 V ac open circuit with no dc
current at 1 KHz
*Sufx K for 10% Tolerance, Sufx M for 20%
** Where there are 2 Mil dash numbers, the
rst is 20% tolerance and the second is
10% tolerance
{1} Add sufx letter “S” to order with tin/lead
solder coat
{2} SRF values above 250MHz are calculated
and are for reference only
{3} These values are also the maximum incre-
mental current for ferrites only. Incremental
current will not change the inductance more
than 5% from the zero DC inductance
measurement
Note:
Gold termination is code “A” nish of
Mil-PRF-83446
Solder termination is code “B” & “F” nish of
Mil-PRF-83446
