Panasonic EXB 14AT Series Manual

Chip Attenuator
EXB type
EXB 14AT, 24AT
Features
● Unbalanced π type attenuator circuit in one chip
EXB14AT (0.8 mm×0.6 mm) , EXB24AT (1.0 mm×1.0 mm)
● Reduced mounting area
EXB14AT：About 60 % smaller than the area of an attenuator circuit consisting of three 0603 chip
resistors, almost equal to the area of three 0402 chip resistors
EXB24AT：About 50 % smaller than the area of an attenuator circuit consisting of three 1005 chip
resistors, almost equal to the area of three 0603 chip resistors
● Mounting cost reduction : (Only 1 chip placed as compared to 3)
● Attenuation : 1 dB to 10 dB
● RoHS compliant
Recommended applications
● Attenuation / level control / impedance matching of high frequency
(communication signalling equipment cellular phones(GSM, CDMA, PDC, etc.), PHS, PDAs)
