CHIP ATTENUATORS
KAMAYA OHM
RAC10 1A, RAC16 1A, 2A
•
Features
1. The RAC10 1A and RAC16 1A, 2A Series are small size chip
attenuators, suitable for high density surface packaging.
2.Suitable for use as DC and up to UHF band frequencies.
3.Similar foot print for chip resistor networks.
4.Standard impedance of 50 ohm and 75 ohm are available up to 600
ohm available on request.
5.Replaces conventional attenuation circuits with one chip in place of
three discrete resistors.
