The CAP-PPI-0201BB-001 from Passive Plus is a substrate scalable Global Model™ for the Passive Plus P/N 0201BB surface mount chip capacitor family. The models have been developed for use with microstrip applications and account for substrate (or printed circuit board) related parasitic effects up to 65 GHz.
Substrate height, dielectric constant, loss tangent, interconnect metal thickness, component tolerance, pad width, pad length and pad gap are model input parameters. Models account for up to two higher-order resonant frequency pairs beyond the fundamental series resonant frequency. Accurate effective series resistance (ESR) is modeled over the frequency range. A Sim mode switch allows pad stack effects to be disabled.
The applications for which these parts are intended require small, surface-mountable (SMT) devices with low insertion losses and reflections across RF frequencies extending from the tens of KHz to the tens of GHz, and temperatures typically ranging from -55 to +125 Degrees C. Applications are primarily found in the “signal integrity” market: Optoelectronics/high- speed data; ROSA/TOSA (Transmit/Receive optical subassemblies); SONET(Synchronous Optical Networks); broadband test equipment; and broadband microwave and millimeter wave amplifiers and oscillators. Customers requiring surface-mountable, 10 nF or 100 nF X7R capacitors that provide resonance-free, low insertion loss, low reflection operation over extremely large RF bandwidths will be well served by Passive Plus’s BB series.
