This comprehensive guide explores every aspect of this remarkable component, from its technical specifications to its diverse applications in modern electronics.

In-Depth Product Analysis

Technical Specifications

The C0805T105K3RAL offers an optimal balance of performance and reliability with these key parameters:

• Capacitance: 1 F (105) 10% tolerance
• Voltage Rating: 25V DC
• Dielectric Material: X7R temperature-stable formulation
• Temperature Range: -55 C to +125 C operational
• Package: 0805 (2.0mm 1.25mm) case size
• Thickness: 1.40mm maximum profile

Why X7R Dielectric Matters

The X7R classification indicates this capacitor maintains its capacitance within 15% across its entire temperature range (-55 C to +125 C). This makes it superior to Y5V or Z5U dielectrics for applications experiencing temperature fluctuations.
