Filtered Terminal Block Specifications
1.0 Scope
This specification describes the basic performance require-
ments of TUSONIX Filtered Terminal Blocks.
2.0 Capacitance
2.1 Measurement Conditions: Capacitance measured at
25°± 2°C, 50% max R.H. and Frequency of 1 KHz @
1± 0.2VRMS.
2.2 Capacitance: 2000pF Minimum
3.0 Insertion Loss
3.1 Measurement Conditions: Insertion Loss values listed
are measured in a 50Ω system at 25°C± 2°C under no-
load conditions.
3.2 Insertion Loss: The Insertion Loss values listed are
minimum values under indicated conditions.
3.3 Listed Insertion Loss data is a measurement of filter
performance in a matched 50Ω system. It is highly
recommended that filter perfomance be verified under
actual circuit operation conditions.
4.0 Operating Conditions
Filters are designed to operate continuously at the tem-
perature, voltage and current stated for each TUSONIX
part number.
Withstanding Voltage
5.0 Dielectric Withstanding Voltage
Filters shall withstand a 1500VAC voltage applied between
the screw terminal and ground plane for 1 minute. Surge
current shall be limited to a maximum of 50mA.
6.0 Insulation Resistance
Measured at 25°C± 2°C with 100VDC and charging current
limited to 50mA max. The IR after two minutes maximum
shall be a minimum of 10,000 Megohms.
APPLICATION
APPLICATION
Recognized by UL, the TUSONIX Filtered
Terminal Block is specifically designed to
save time and money for EMI Filtering appli-
cations. By combining a filtering component
with an industry standard terminal block,
TUSONIX has created an effective barrier to
EMI noise. TUSONIX’ Filtered Terminal
Blocks allow the engineer to eliminate EMI
using an existing mechanical design element
combined with the excellent perfomance of
a
π
filter.
TUSONIX’ commitment to excellence and
service allows for customization of the filtered
terminal blocks to meet your specific EMC
qualifications.
Backed by more than 60 years of ce-
ramic component production experience,
TUSONIX Filtered Teminal Blocks meet your
demanding requirements.
