● 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

Chip Attenuator

0302, 0404

Type:

EXB 14AT, 24AT

● Attenuation / level control / impedance matching of high frequency (communication signalling equipment cellular

phones(GSM, CDMA, PDC, etc.), PHS, PDAs)

(EXB14AT, EXB24AT)
