Low-Pass Filter Array Replaces 12 Discretes

With primary applications in signal filtering, EMI suppression and mobile or cordless systems, the 0612 low-pass filter array provides four equivalent RCR T-Filters with a dual common ground, resulting in the equivalent of eight resistors and four capacitors in a single chip. The array yields a more efficient filter, thereby allowing cell phone manufacturers to produce phones with better signal to noise ratios.The filter array has the ability to filter four circuits with one package, providing distributed capacitance and shielded resistance. The integrated package also has lower parasitic capacitance when compared with discretes, which translates into improved frequency response and broader filter attenuation.Applications include T-Filter designs, low pass filtering, I/O cables, digital circuits, EMI filtering, digital control lines, and IF filters.
