EMI/RFI Surface Mount π & C Filters for SMT Applications  
APPLICATION  
EMI/RFI Filter Specifications  
TUSONIX 4700/4701 Series π Filters & 4702  
Series C Filters are used where cost and space  
savings have priority and improved insertion loss  
is required.  
1.0 Scope  
This specification describes the basic performance  
require-ments of the CTS EMI/RFI surface mount Filters.  
2.0 Capacitance  
2.1 Measurement Conditions: Capacitance measured at  
25° 2°Cꢀ 5ꢁ0 maꢂ R.ꢃ. and Frequencꢄ of 1 ꢅꢃH ꢆ  
1 ꢁ.2ꢇRMꢈ.  
TUSONIXunique design makes the filter suit-  
able for common production soldering processes.  
2.2 Capacitance Tolerance: Listed capacitances are  
minimum value at 25° 2°C unless otherꢉise specified.  
TUSONIXstate-of-the-art manufacturing pro-  
cess results in excellent electrical and mechani-  
cal performance. The square or round body al-  
lows easy handling, positioning and soldering  
onto the PCB. This is another cost effective qual-  
ity product from TUSONIX.  
3.0 Insertion Loss  
3.1 Measurement Conditions: Attenuations listed are  
measured in a 5ꢁsꢄstem at 25°C 2°C under no-load  
conditions (per MIL-ꢈTD-22ꢁ).  
3.2 Insertion Loss Tolerance: The attenuations listed are  
tꢄpical values under indicated conditions.  
3.3 Listed insertion loss data is a measurement of filter  
performance in a matched 5ꢁsꢄstem. It is highlꢄ  
recommended that filter performance be verified under  
actual circuit operation conditions.  
FEATURES  
Excellent Performance  
Easy Placement  
Excellent Solderability  
Reduces PCB Component Count  
4.0 Operating Conditions  
Filters are designed to operate continuouslꢄ at the tem-  
peratureꢀ voltage and current stated for each TUꢈONIX  
part number. Operating temperature ranges are from -55°C  
to either 85°C or 125°C.
