Integrated Passives Part Number Explanation

General format is: FFFFPPCCVBBBBT where:

FFFF is the 4 digit Frequency in Megahertz (unless otherwise specified)

PP is the 2 character Product code

AT = Antenna
AM = Antenna Module Assembly
AS = Antenna Switch Module
AD = Dual-Band Antenna
BL = Balun
BD = Balun, Dual-Band
BM = Chipset Specific Impedance-Matched Balun or Balun-Filter
BP = Band Pass Filter
CD = Coupler, Dual Band
CP = Coupler
CF = Coupler Filter
CH = Coupler Hybrid
CR = Ceramic Resonator

DF = Differential Filter
DP = Diplexer
DM = Diplexer Module
FA = Filter Array
FB = Filter-Balun
FM = Front-End Module
HP = High Pass Filter
LD = Low Pass Filter, Dual-Band
LP = Low Pass Filter
NF = Notch Filter (Band-Stop Filter)
PC = Passive Component
PD = Power Divider
TP = Triplexer

CC is the 2-digit Case Size Code (e.g. 07 is EIA 0402, 14 is EIA 0603, 15 is EIA 0805, 18 is EIA 1206)

V is a 1 character Version/Revision code

BBBB is 3 or 4 digit Bandwidth, differential impedance (baluns only), or specific chipset denomination

For components that have a center frequency of more than 9999MHz, an “R” multiplier is placed within the four BBBB digits.
For example, a 10100MHz Balun, is represented in 4 digits using the R in “10R1=10100MHz

T is the character tape code:

Tape materialCode
Paper Tape standard (EIA 0603 and smaller)T
Embossed Tape standard (EIA 0805 and larger)E
Paper Tape rotated (non-std, EIA 0603 and smaller)*A
Embossed Tape rotated (non-std, EIA 0805 and larger)*R

*Only available for selected components, please consult the factor for availability and MOQs that apply
