Dimensions for Ceramic Leaded Capacitor.
X7R High Voltage Leaded Ceramic Capacitors
X7R dielectrics are considered “temperature stable” and fall into EIA Class II materials. X7R dielectric materials are ferroelectric and offer higher capacitance than Class I materials, however the capacitance change is limited to +/- 15% from -55°C to +125°C.These capacitors are suitable for blocking, bypassing, decoupling, filtering and frequency discriminating circuit applications where Q (low loss) and stability of capacitance characteristics are not critical.
