Primary Electrical Parameters of 08055U130GAT2A Series Capacitors

The 08055U130GAT2A offers a nominal capacitance of 13 pF with a tight tolerance of ±2%, measured at 1 MHz. The capacitor utilizes the C0G (NP0) dielectric material, delivering a near-zero temperature coefficient of capacitance (TCC) defined as 0 ±30 ppm/°C over a wide operating temperature range from -55°C to +125°C. Capacitance stability across temperature ensures reliable performance in fluctuating thermal environments typical in RF hardware. Insulation resistance (IR) parameters are robust, with minimum values of 10^12 Ω at 25°C and 10^11 Ω at 125°C, then tested at the rated working voltage. Working voltage for the 0805 size capacitors in the “U” Series includes options up to 200 V DC; however, this specific model is rated to 50 V DC. The dielectric withstand voltage (DWV) meets 250% of the rated voltage, reinforcing reliability under transient conditions. ESR values are kept ultra low, verified using specialized instrumentation such as the Boonton 34A meter, contributing to minimal insertion loss in RF circuits. Laser marking adheres to EIA J standards, facilitating efficient identification and traceability during production.

Performance Factors for 08055U130GAT2A in RF and Microwave Applications

The ultra low ESR characteristic intrinsic to the “U” Series capacitors translates directly into enhanced signal fidelity for RF and microwave designs. Low ESR reduces unwanted resistive losses at high frequencies, enabling better Q-factors and improved impedance matching in filters and resonant circuits. Class 1 C0G dielectric stability offers linear capacitance behavior with negligible variation due to temperature, voltage bias, or frequency shifts, essential for phase-sensitive applications such as oscillators and antenna tuning networks. The capacitor’s tight capacitance tolerance and high insulation resistance enhance noise suppression and reduce the likelihood of distortion in sensitive communication front-ends. Designers should consider these factors when selecting decoupling and bypass capacitors in RF front-end modules, where stability and minimal parasitic effects are paramount.
