Passive Plus Inc. (PPI) has developed a series of broadband capacitors available in four different case sizes: 01005BB, 0201BB, 0402BB and 0805BB. Values available are 10 nF (10,000 pF) and 100 nF (100,000 pF).

These capacitors are intended primarily for coupling RF signals or, occasionally, for bypassing them to ground, while blocking DC. The applications for which they are intended require small, surface-mountable devices that provide low RF impedances, i.e., low insertion losses and reflections, across extremely large RF bandwidths and temperatures typically ranging from -55°C to +125°C.

Applications for the Broadband series are primarily found in the "signal integrity" market:

• Optoelectronics/highspeed data
• ROSA/TOSA (Transmit/Receive optical subassemblies)
• SONET (Synchronous Optical Networks)
• Broadband test equipment
• Broadband microwave and millimeter wave amplifiers and oscillators

Customers requiring surface-mountable, 10 or 100 nF capacitors that provide resonance-free, low insertion loss, low reflection operation over extremely large RF bandwidths will be well served by PPI's Broadband series.
