Ordering Procedure - Examples

Filter Type (THP)

Cut-Off Frequency

Number of Sections 
(See Graph)

 Impedance (Ohms) B
(for BNC Connectors)
S
(for SMA Connectors)
Examples below
THP500P2050B 500P = 500 MHz 2 050 = 50 Ohms B
THP50P03075S 50P0 = 50.0 MHz 3 075 = 75 Ohms S
THP5P554100B 5P55 = 5.55 MHz 4 100 = 100 Ohms B
Cut-off Frequency can be any 4 characters from .5MHz (00P5) to 1000 MHz (1000)
"P" represents the decimal point and, if used, is valid only in the 2, 3, and 4th position

Examples: 5P55 = 5.55 MHz,  58P7 = 58.7 MHz,  500P = 500MHz,  1000 = 1000 MHz
