ATTENUATION VALUE
1 dB to 20 dB shown in the table of “Attenuation value,
tolerance v.s. 12 NC code”.
(6) RESISTOR TERMINATIONS
L = Lead free terminations (pure Tin)
ORDERING EXAMPLE
The ordering code of an ATV321 attenuator with
2±0.3 dB attenuation, supplied in 7-inch tape reel is:
ATV321CR-072dBL.
NOTE
1. The “L” at the end of the code is only for ordering. On the reel
label, the standard CTC will be mentioned an additional stamp
“LFP”= lead free production.
2. Products with lead in terminations fulfil the same requirements
as mentioned in this datasheet.
3. Products with lead in terminations will be phased out in the
coming months (before July 1st, 2006)
SCOPE
This specification describes ATV321 series chip attenuators with lead-free terminations made by thick film process.
ORDERING INFORMATION
Part number is identified by the series, size, tolerance, packing type, temperature coefficient, taping reel and
resistance value.
