3 / 20 page 7 1 Accu-F® / Accu-P® Thin-Film Chip Capacitors ACCU-F ® TECHNOLOGY The use of very low-loss dielectric materials, silicon dioxide and silicon oxynitride, in conjunction with highly conductive electrode metals results in low ESR and high Q. These high-frequency characteristics change at a slower rate with increasing frequency than for ceramic microwave capacitors. Because of the thin-film technology, the above-mentioned frequency characteristics are obtained without significant compromise of properties required for surface mounting. The main Accu-F® properties are: • Internationally agreed sizes with excellent dimensional control. • Small size chip capacitors (0603) are available. • Tight capacitance tolerances. • Low ESR at VHF, UHF and microwave frequencies. • High stability with respect to time, temperature, frequency and voltage variation. • Nickel/solder-coated terminations to provide excellent solderability and leach resistance. ACCU-F ® FEATURES Accu-F® meets the fast-growing demand for low-loss (high-Q) capacitors for use in surface mount technology espe- cially for the mobile communications market, such as cellular radio of 450 and 900 MHz, UHF walkie-talkies, UHF cordless telephones to 2.3 GHz, low noise blocks at 11-12.5 GHz and for other VHF, UHF and microwave applications. Accu-F® is currently unique in its ability to offer very low capacitance values (0.1pF) and very tight capacitance tolerances (±0.05pF). Typically Accu-F® will be used in small signal applications in VCO’s, matching networks, filters, etc. Inspection test and quality control procedures in accordance with ISO 9001, CECC, IECQ and USA MIL Standards yield products of the highest quality. APPLICATIONS Cellular Communications CT2/PCN (Cordless Telephone/Personal Comm. Networks) Satellite TV Cable TV GPS (Global Positioning Systems) Vehicle Location Systems Vehicle Alarm Systems Paging Military Communications Radar Systems Video Switching Test & Measurements Filters VCO’s Matching Networks APPROVALS ISO 9001 ACCU-P ® TECHNOLOGY As in the Accu-F® series the use of very low-loss dielectric materials (silicon dioxide and silicon oxynitride) in conjunction with highly conductive electrode metals results in low ESR and high Q. At high frequency these characteristics change at a slower rate with increasing frequency than conventional ceramic microwave capacitors. Using thin-film technology, the above-mentioned frequency characteristics are obtained with- out significant compromise of properties required for surface mounting. The use of high thermal conductivity materials results in excellent RF power handling capabilities. The main Accu-P® properties are: • Enhanced RF power handling capability. • Improved mechanical characteristics. • Internationally agreed sizes with excellent dimensional control. • Ultra Small size chip capacitors (0201) are available. • Tight capacitance tolerances. • Low ESR at UHF, VHF, and microwave frequencies. • High-stability with respect to time, temperature, frequency and voltage variation. • High temperature nickel/solder-coated terminations as stan- dard to provide excellent solderability and leach resistance. ACCU-P ® FEATURES • Minimal batch to batch variability of parameters at high fre- quency. • The Accu-P® has the same unique features as the Accu-F® capacitor such as low ESR, high Q, availability of very low capacitance values and very tight capacitance tolerances. • The RF power handling capability of the Accu-P® allows for its usage in both small signal and RF power applications. • Inspection, test and quality control procedures in accor- dance with ISO 9001, CECC, IECQ and USA MIL Standards guarantee product of the highest quality. • Hand soldering Accu-P®: Due to their construction utilizing relatively high thermal conductivity materials, Accu-P’s have become the preferred device in R & D labs and production environments where hand soldering is used. Accu-P’s are available in all sizes and are electrically identi- cal to their Accu-F counterparts. APPLICATIONS Cellular Communications CT2/PCN (Cordless Telephone/Personal Comm.
