TUSONIX, Inc. is an ISO 9001 Registered Firm UL Recognized Filtered Terminal Block APPLICATION Filtered Terminal Block Specifications Recognized by UL, the TUSONIX Filtered Terminal Block is specifically designed to save time and money for EMI Filtering applications. 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. 1.0 Scope This specification describes the basic performance requirements of TUSONIX Filtered Terminal Blocks. 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 ceramic component production experience, TUSONIX Filtered Teminal Blocks meet your demanding requirements. BENEFITS • • • • Saves Labor and Space Consistent Panel Layout Solves EMI Problems Meets Specific Requirements 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 noload 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 temperature, voltage and current stated for each TUSONIX part number. 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.
