Its low signal loss and high Q factor make it a preferred choice for applications requiring reliable performance under varying environmental conditions.
Structure and Working Principle
The TCC0402COG2R7B500AT consists of multiple layers of ceramic dielectric material sandwiched between conductive electrodes. The COG (NPO) dielectric provides minimal capacitance change over a wide temperature range (-55°C to +125°C), ensuring stable performance. The 0402 package size (1.0mm x 0.5mm) allows for high-density PCB layouts. When a voltage is applied, the capacitor stores energy in its electric field, releasing it as needed to stabilize voltage and filter noise in circuits. The high Q factor of the TCC0402COG2R7B500AT indicates low energy loss, making it efficient for high-frequency applications.

The compact 0402 package size allows for high-density circuit designs without sacrificing performance. Additionally, this capacitor exhibits low signal loss and a high Q factor, which are critical for RF and high-frequency circuits. Its tight capacitance tolerance (±0.05pF) ensures consistent performance across batches, reducing the need for recalibration in sensitive applications.
Application Areas
The TCC0402COG2R7B500AT is widely used in industries requiring high precision and reliability. In telecommunications, it is employed in RF filters, oscillators, and matching networks. Automotive electronics benefit from its stability in harsh environments, such as engine control units and infotainment systems. Industrial equipment, including sensors and measurement devices, also utilize this capacitor for its consistent performance. Its low signal loss and high Q factor make it ideal for applications where signal integrity is paramount, such as medical devices and aerospace systems.
Maintenance and Precautions
To ensure the longevity and performance of the TCC0402COG2R7B500AT, proper handling and installation are essential. Avoid exposing the capacitor to excessive mechanical stress, which can damage the ceramic layers. Use appropriate soldering techniques, such as reflow soldering, to prevent thermal shock. Storage conditions should be controlled to avoid moisture absorption, which can affect performance. When designing circuits, ensure that the operating voltage does not exceed the capacitor's rated voltage to prevent breakdown and failure.
B2B Procurement Guide
When procuring the TCC0402COG2R7B500AT, consider factors such as volume requirements, lead times, and supplier reliability. Bulk purchases typically offer cost savings, but ensure that the supplier can meet quality standards. Verify the dielectric type (COG/NPO) and capacitance tolerance to match your application needs. It is also advisable to request samples for testing before large-scale orders. Compare prices from multiple suppliers, but prioritize quality and consistency over cost savings alone. Ensure that the supplier provides proper documentation, including datasheets and compliance certificates.
