TaNCap® T-Filter
Network
IRC’s TaNCap® T-filter networks are designed for the most demanding low pass filter applications. These TaNSil®
technology thin film networks offer attenuation of high frequency signal components with minimal inductive effects.
EMI/RFI reduction, improved signal quality and reduction of false triggers in digital circuits while minimizing
insertion loss are characteristics of these silicon based filter networks.
The SOIC, QSOP, and TSSOP packages offer a high level of integration in today’s most popular surface mount
configurations. Up to 24 discrete components are replaced by one T-filter network.
The TaNCap® series of resistor-capacitor networks are manufactured using IRC’s military and space proven
tantalum nitride thin film technology. For high reliability combined with superior performance, use IRC TaNCap®
T-Filter Networks for your most demanding, high speed analog and digital designs.
