5 ATTENUATION VALUE

The ordering code of an ATV321 attenuator with

2±0.3 dB attenuation, supplied in 7-inch tape reel is:

ATV321CR-072dBL.

1 dB to 20 dB shown in the table of “Attenuation value,

tolerance v.s. 12 NC code”.

(6) RESISTOR TERMINATIONS

NOTE

L = Lead free terminations (pure Tin)

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)
